However, the performance of the Evolution One largely undercuts those preconceptions and redefines what it means to be a top-tier monoblock amp in 2019. . This scenario was much different than that presented by, say, a single-ended triode amp, whose distortion spectrum is rich in even harmonics and as a result dominates a systems voicing. Lets see if the EVO STA can beat the AMG STA dual mono config . So now Im thinking to myself, can a Class D amp really dish out this sort of imaging? We called that Only Distortion Cancellation (ODC) design, continued advancing the state-of-the-art Class-D for the past decade. It seems to me that in this case, NuPrime has made the right choices, opting for reduced distortion and noise. Pulling out theAMG-STAfor a final direct comparison, it becomes clear that this amp is quite different still. According to NuPrime, it was selected on the basis of its natural, tonally dense, and warm sound character. Don't worry, though, as I will also compare the Evolution STA to the very affordable NuPrime AMG-STA and ST-10. NuPrime STA-9 Power Amplifier - 120W x 2 (8 Ohms) & 290W Mono ( Oh My! ) High quality copper PCB trace instead of usual cables are used to connect the power supply to the amplifiers circuitry, maximizing power delivery. The Evolution Two is a mono amplifier (RMS Power 300W@8 Ohm, 600W@4 Ohm) that offers a breakthrough in distortion reduction and it is the most powerful, dynamic, natural and detailed amplifier in all Nuprime series. For instance, the Big Swiss amp remains the King of resolution and refinement. Perfect Condition. They remain very different, each with its respective strong suits. Second, resolution of low-level detail was superb. This amplifier sounds full-bodied and it can certainly sound smooth, warm, or romantic but only if the recording dictates it. Frequency response: 10Hz50kHz (-3dB) With the Evolution STA, NuPrime has delivered an amplifier that manages to strike a beautiful balance between the strong qualities of the ST-10 and the AMG-STA, while raising the overall performance even further. The ST10 is even a little bit more of a party animal but less refined than the EVO STA. While balanced interlinks usually tend to sound wider than single-ended connections, the difference here is larger than what I am used to hearing between the two connections. NUPRIME EVO-STA Reference Class Stereo Amplifier FCC Notice - Declaration of Conformity Information This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. Between the CH and the NuPrime, certain key aspects have certainly noticeably shifted, but on the surface of it, and in an absolute sense, there is not very much to indicate that we just switched from a 31 K amplifier to one costing only 5 K. Honestly, it was more like switching from one high-end amplifier to another, invoking differences catering more to taste than to absolute quality. The AMG-STA sure does not have the concrete authority or the sonorous robustness of the ST-10 and Evolution STA, not their timbral fullness, but it does actually come closer to the CH A1.5 in terms of fluidity and refinement. Then the AMG comparison came a little out of the blue for me, but if this was on purpose then all is good , It harks back to the introduction where I mentioned that the intention was to include elements of the ST-10 and the AMG-STA in the new Evolution STA amplifier:-). Cheers! GaN MOSFETs have become popular in the last few years for Class D switching applications, and while NuPrime has experimented with these devices, it concluded that the familiar silicon MOSFETs allow better control of an amps sonic character. They are directly connected to a DAC Totaldac D1 Core with volume control through KLR cables. As such, they enhance the bass impact, solidity, and dynamics, making the amp even more of a rock star. After owning the AMG STA in dual mono setup I switched to the Evolution STA. For all of its solidity and enthusiasm, the amp is a little on the dry side and it could do with just a little bit more refinement. Is there any sense in comparing the NuPrime to an amp costing over four times as much? They remain very different, each with its respective strong suits. As far as I am concerned, this is merely a matter of perspective and not one of quality. Lets see if the EVO STA can beat the AMG STA dual mono config . Reading your comments the more Im convinced that combining my Audio-Gd HE-1 preamp, the big brother to the Master 1 you have tested, with the NuPrime AMG STA power amp in mono mode will give the best sounding result Im after with my open baffle speakers. Not all listeners are bothered by this though. Good morning Christiaan.I have a question,would the nuprime evolution sta match well with the Totem Tribe Towers.If not which amp would you recommend to me.No i have an Arcam avr 850.Thanks in advance. This amplifier sounds full-bodied and it can sound smooth or warm so long as the recording dictates it. We called that Only Distortion Cancellation (ODC) design, continued advancing the state-of-the-art Class-D for the past decade. Nice review Christiaan! In this respect, it turned out to be a reference tool by providing a truthful sonic snapshot of upstream components. The entire power path is compatible with 40-ampere current flow and features low-resistance terminals. Furutech FP900 RCA input connectors and Eichmann binding post. In addition to this feedback, the STA derives an error signal after the output stage and filter that is part of a proprietary distortion-canceling circuit that reportedly reduces noise. After having favorably reviewed the ST-10 and the AMG-STA and having concluded that they have mutually exclusive strong areas, Jason Lim of NuPrime later mentioned that they were working on a new amplifier that would combine the strong points of both amplifiers. }. Great to hear Phil! Expensive. Little more dark but also more authority in general. but I feel that the AMG-STA also sounds airier and more refined and certainly more fluid. All comments are welcome but I regret that I no longer have the time to respond to all questions. The latter are dipoles speakers that you have used extensively in the past. To me, this manufacturer is known to be different from the rest and, just like NuPrime, to deliver products with a very good cost to performance ratio. For instance, the Big Swiss amp remains the King of resolution and refinement. Dont worry, though, as I will also compare the Evolution STA to the very affordable NuPrime AMG-STA and ST-10. They are directly connected to a DAC Totaldac D1 Core with volume control through KLR cables. And it is not particularly lush or liquid. --> Amp Comparison & Sonic Characteristic--> Amp Design & NuPrime's Advantages, #text-3439104615 { Right out of the box it was clear that this $4995 stereo amplifier meant business. color: rgb(0,0,0); What could be your favorite option between the two with Martin Logan EL 11 ? EVO STA WATT / THD / S/N (typical) : @5W (0.0025% ,95db) , @50W (0.007% , 105db) , @100W (0.01% , 110db), Standby Power : 1.5W @ 115V outlet, 1.7W @ 230V outlet, Idle Power : 24W @ 115V outlet, 26W @ 230V outlet, Worldwide AC voltage: (115VAC / 230VAC) with Voltage Select Switch. Its a 4-ohm nominal load, though it dips to around 3 ohms and demands a lot of current. As cliche as it sounds, across the frequency spectrum, I was hearing things that I swear I had not heard before with the AMG STAs. With the Evolution STA, NuPrime has delivered an amplifier that manages to strike a beautiful balance between the strong qualities of the ST-10 and the AMG-STA, while raising the overall performance even further. This involvement could still be enjoyed at lower volumes than with other amps. The NuPrime Evolution STA offers a breakthrough in distortion reduction. A separate review will be forthcoming and meanwhile, Ill have something to think about. The NuPrime Evolution STA offers a breakthrough in distortion reduction. Its level of micro dynamic finesse, purity of tone, resolution of individual voices in a complex mix, and rhythmic drive kept me listening late into the night. By the same token, the Evolution STA most definitely does not have the kind of bass that youd expect from a Class-D amplifier, far from it actually. The balanced vs imbalanced switch has a lot of impact on the restitution, much better with balanced position. No sex appeal here. A new input stage with a 1M input impedance. It has been suggested to me that a fair comparison would be to use two AMG-STA amplifiers in mono mode and I guess the same is true for the ST-10 versus theST-10 M. I have followed up on this and a second AMG-STA is actually on its way, but already knowing what the pair brings in addition to a single AMG-STA, I dont feel that this would alter my conclusion. And bass lines were punchy and tightly defined. EUR 3,995.00 And perhaps due to its squarer and less refined delivery, the ST-10 also has a slightly more urgent bounce in its step. Natural and pure due to ultra-low distortion, Cleaner background that provides greater detail and nuances, Power Output (RMS): 230W @ 8 Ohms , 310W @ 4 Ohms, Power Output (peak): 270W @ 8 Ohms , 360W @ 4 Ohms. Simultaneously in for review are new speaker cables byMad Scientist. Audio-GD HE-1 Mk2 The only area where it is competitive is in its dynamic delivery of power. I still thinking of purchasing them again fir my second setup. Mated with a compatible speaker load, it is deserving of an enthusiastic endorsement. I have good hopes for the Grimm Audio MU1, HoloAudio Spring 3 DAC, EVO STA combination (Jorma digital and Driade analog interlinks) together with my Magico A1s. The amp is also very linear and quite detailed but not revealing to the point of being analytical, let alone clinical. Im not sure if the manufacturer has intended to position it above the Evolution One, but if you ask me, the Evolution STA is a more satisfying amplifier. While 2 AMG STAs sound better than a single unit, they still excel in fluidity, refinement, nimbleness, and air while the EVO STA excels in robustness, body, impact, and tonal saturation. Reference Sound. No probs, Vincent, I appreciate the diligence and its always good to get feedback, especially since I am certainly not fool-proof! NuPrime STA-9, MCH-K38, IDA-6, IDA-16, STA-9X, AMG STA, The following models speaker outputs can not be connected directly to sub woofer input: The Evolution STA (NZ$8500 incuding GST & delivery) is an enigmatic and interesting beast to say the least. A lot of times I surprise myself how good the sound is, so close to really. NuPrime IDA-8 Integrated Amplifier -100W x 2 (8-Ohm) . Press Esc to cancel. Notify me when new comments are added (check your spam folder), This site is protected by reCAPTCHA. Both cables complement the Evolution STA in its strong areas but what these very neutral and very honest cables do not do is enhance the refinement or fluidity. Not all listeners are bothered by this though. Price with Selection: $4,995.00 - + Add to Cart Details The NuPrime Evolution STA offers a breakthrough in distortion reduction. I like the sound of Pass Labs, Constellation, and VAC amps, yet not even considering the price, size, and heat difference, feel like I like the Evos better. Now that the Evolution Two has arrived.. time for a review of the new kid on the block? Taipei City, Taiwan Its superbly natural timbre, combined with its exemplary solidity makes the best of piano and other percussive acoustic instruments. I listen to a lot of classical music and the refinement and fluidity you say these amps are capable of will suit this genre of music even more than the Evolution STA. The amp sounds very much of one piece and its midrange follows the superbly well-balanced foundation in all parameters. A lot of times I surprise myself how good the sound is, so close to really. Finally, it was time for the Analysis Audio Omega. Item #649994878 Info: NuPrime Audio Evolution STA Power Amplifier Cheers! Hello my friend. The power supply has been enhanced to deliver cleaner and more stable power with lower noise floor. The Evolution One presents the most untainted and transparent sound with a completely flawless background. While the Black Magic cables are not cheap, they do still deliver great value for money. This scenario was much different than that presented by, say, a single-ended triode amp, whose distortion spectrum is rich in even harmonics and as a result dominates a systems voicing. But to offset this, the NuPrime actually overshadows the CH in a couple of areas. Yes I refer to the NuPrime EVO STA. A typical feedback error correction design inverts the output signal for summation with the original input signal to derive the negative error signal, which adds to the next cycle of the input signal to form a more accurate output signal. Coined the Only Distortion Cancellation (ODC) design, NuPrime has continued advancing the state-of-the-art Class-D for the past decade. On balance, while I still enjoy the ultra-bouncy kind of loud-mouth ST-10 and I respect the heck out of the AMG-STA each at their friendly price points, the Evolution STA is most definitely superior to both. It totally depends on what you are personally after. Thanks for your answer. It has been suggested to me that a fair comparison would be to use two AMG-STA amplifiers in mono mode and I guess the same is true for the ST-10 versus the ST-10 M. I have followed up on this and a second AMG-STA is actually on its way, but already knowing what the pair brings in addition to a single AMG-STA, I dont feel that this would alter my conclusion. Orchestral crescendos were unfurled with tremendous power and control. While that may not make them the ideal cables for everyone, I must admit that they have blown me away with the immensely energetic, toe-tapping, dynamic, and joyful presentation that they elicit from both the NuPrime and the CH A1.5. First and foremost, it paints the complete musical picture while sounding nothing like your typical Class-D amplifier. This breakthrough improvement in Class-D design resulted in a natural and pure sound characteristic. With the Evolution STA, NuPrime has delivered an amplifier that manages to strike a beautiful balance between the strong qualities of the ST-10 and the AMG-STA, while raising the overall performance even further. The Pass is not quite as fluid, airy, or refined as I would like and given the EVO STAs character, I dont think that would result in an ideal match. High Quality copper strips instead of usual cables are used to connect the power supply to the amplifiers circuitry, maximizing power delivery. The linear power supply benefits from a 550W, ultra-thin, toroidal power transformer and a total of 52,000uF filter capacitance. This allows silicon-device switching at a frequency of 650700kHz, approaching GaN device territory. That fundamental circuitrealized with many refinementsforms the heart of the M225. Simple concept. As it turns out, these speaker cables have very similar strengths as the NuPrime amplifier. Thinking of theEvolution One, when I reviewed it, I found that it sounded a little too controlled, its presentation verging in the direction of cerebral rather than particularly gushing or singing. Its deeply saturated and full-bodied yet fast, articulate, and nimble. The 550W high-power ultra-thin toroidal transformer power supply has been enhanced to deliver cleaner and more stable power with lower noise floor. Both RCA and XLR inputs are provided on the rear panel. All these pushes the performance of the Evolution One to yet a higher level! Regular price $1,229 View. Almost the polar opposite in sonic presentation from the NuPrime AMG STA but a great amp indeed. And if I had to choose between these two options, I for one would opt for the one that provides the most fun and engagement, which is the Evolution STA. Hi Ben, did you already experience the Evo STA combined with the Audio-GD HE1 and if so: was it the tube or transistor version? The AMG is never lacking control, not even with Magico Q5s which are really hard to drive. A mono trigger cable shorts pin 2 and pin 3, it can be used to connect the Nuprime device to another devices trigger that only uses a mono cable. The custom select iron core linear power supply has a dual routing for dual outputs, with dual wire per output, to function as two power supplies for dual-mono implementation. This is a truly end game type amplifier for me., First up was the Fleetwood Sound De Ville loudspeaker, a fairly benign 8-ohm bass-reflex load. We called that Only Distortion Cancellation (ODC) design, continued advancing the state-of-the-art Class-D for the past decade. And while the Jormas inherent refinement and fluidity add a gentle amount of forgiving friendliness, the Black Magic cables simply tell it like it is, warts and all. I listen to a lot of classical music and the refinement and fluidity you say these amps are capable of will suit this genre of music even more than the Evolution STA. It has dual windings for dual outputsto allow the left and right channels to be configured as mono amps. When considering Class-D amplifiers,timbreor tonality is an important aspect. There seems to be a big gap between affordable preamps and the high-end with precious little in between. Hi Vincent, to which setup are you referring? If going second-hand, I think I would prefer a Jeff Rowland preamp such as the Synergy 2i. All too often, amplifiers of this sort sound deprived of harmonics and saturation, but here too, the Evolution STA shines. If you find that you are, and you find this aspect more important than some others, then the ST-10 and EVO STA are probably the better options for you. The more expensive 4-Core variant, however, sounds tonally considerably richer, is wider in soundstaging and makes the NuPrime sound extremely well-balanced, in addition to incredibly engaging. It is full-size, unrestrained, rock-solid, full-bodied, and weighty, but not in a thick, enriched, or loosely gripped manner as it can be with many powerhouse amplifiers, such as I feel is the case with certain Bryston amplifiers such as the 4B cubed. Rather, my first impression was one of amazement. The more affordable 2-Core version adds a remarkable tightness and coherence and makes the amp sound even more exciting but it is also a little lean and forward and it narrows the width of the soundstage compared to the Jorma and the Driade cables. If desired, you can always add a second unit. } The DAC is subtil, revealing plenty of details, and adding huge depth. NuPrime Evolution One Mono Power Amplifiers, NuPrime Evolution One Review in AudioCircle, NuPrime Evolution One Monoblock Amplifier, http://www.audiocircle.com/index.php?topic=134697.0. A stereo amplifier with dual mono implementation. All voices, especially female vocalists were more natural and captivating. Minor and subtle, yet highly important. In fact, I have been listening to much more symphonic music with these amps, where before there was something unsatisfying about the reproduction of such massive and detailed soundscapes. NuPrime Evolution STA Amplifier [Expired] no longer for sale Average Research Pricing The Evolution STA offers a breakthrough in distortion reduction (Only Distortion Cancellation) and rivals the Evolution One in sound quality. The amp is also very linear and quite detailed but not revealing to the point of being analytical, let alone clinical. NuPrime Evolution STA stereo power amplifier - CHRISTIAAN PUNTER, hifi-advice.com With the Evolution STA, NuPrime presents an amplifier that delivers a breakthrough in distortion reduction. Hi Vincent, A 326S second-hand might be quite nice although I never had much success with my 320S. As a consequence, it simply reflected the character of upstream components. For such application, usually the receiving devices should have DC offset blocking capability because some amplifier by design has floating ground (DC offset) on the speaker outputs. For all of its solidity and enthusiasm, the amp is a little on the dry side and it could do with just a little bit more refinement. After the initial approval, successive comments will appear right away. Re: Two new mono amps: NuPrime Evolution Two and AMG One. Hi Ben, indeed for classical, I would prefer the AMG-STA, either a single amp or the bi-wired pair. Of course, these test bench measurements typically use a resistor as a load and do not reflect the impact of real-world speaker loads. Mated with a compatible speaker load, it is deserving of an enthusiastic endorsement. NuPrime Evolution STA [Expired] no longer for sale. But as I have often found (and as evidenced within the NuPrime range), extra refinement often comes at the cost of some dynamic impact and expression. My OBs use 4x 10 woofers per side so thats why Im thinking the mono d version of the AMG have the power to control the speakers well. And bass lines were punchy and tightly defined. This amplifier sounds full-bodied and it can certainly sound smooth, warm, or romantic but only if the recording dictates it. But I think I know just what to do about that. After re-reading it, it is clear what you intend to say. Thanks Vincent! It also became clear that the GT-21 Ultra offered better image focus, and as a result, more incisive spatial resolution. Indeed, there was the same control, but with a more detailed bass than the AMG STAs. The Evolution STA sounds marvelously energetic, expressive, and utterly coherent with immense neutrality but without tipping over into leanness or coolness. On the Omega, the GT-21 Ultra was just crushing it with stupendous bass slam and macrodynamics that reached Olympian heights.
