NuPrime Evolution STA Allow us to introduce you to latest iteration in NuPrime's innovative amplifier range. NuPrime Evolution STA stereo power amplifier Review by HFA My bad. The amps do not rose-tint of otherwise beautify the sound in any way which does make their performance highly dependent on the recording quality. All too many amplifiers, even Class-AB designs, can make a grand piano sound more like a wall model or even a bit like a synthesizer, but not the Evolution STA. In this respect, it turned out to be a reference tool by providing a truthful sonic snapshot of upstream components. While this will probably not be ideal for the amplifier, it does provide the ideal setup to compare the two amplifiers. The balanced vs imbalanced switch has a lot of impact on the restitution, much better with balanced position. Again, there was nothing of significance to criticize. The high input impedance allows the pre-amplifier to see a much easier load and hence introduces less harmonic distortion and phase delay to the system. On balance, the sound remains quite solid but is now slightly leaner. The only area where it is competitive is in its dynamic delivery of power. One little remark: on page 2 somewhere in the middle you mention AMG-STA which should be Evolution STA I assume. FOR SALE: NuPrime Audio Evolution STA Power Amplifier 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. Do let us know how you get on with the D10! And now that I am making a direct comparison between the Evolution STA and the ST-10, it is very clear that the amplifiers are rightfully positioned in different price categories, the higher-end model indeed being considerably more transparent and more nuanced. As you would expect from an electrostatic midrange and treble, transients were supremely well controlled, while the bass range was reproduced with control and full extension. Minor and subtle, yet highly important. The NuPrime AMG series is, first and foremost, about uncompromised sound quality. Thanks for your answer. NuPrime most powerful, dynamic, natural and detailed mono amplifier that offers a breakthrough in distortion reduction. On my short list are: Such details are presented in a truthful manner without artificial enhancements. text-align: left; #text-3439104615 > * { My gut feeling is that they are nice and lively and direct and the combination with the EVO STA would likely result in a more solid, direct, and robust sound than the Arcam. 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. Latest NuPrime 700KHz high-speed switching Class-D module allows greater resolution to be achieved. NuPrime Evolution DAC 2 - SUMMITHIFI-USA Holo is on the list to review (no timetable yet). Right out of the box it was clear that this $4995 stereo amplifier meant business. Free shipping for many products! The main difference here is that the A1.5 tends to project more to the rear while the Evolution STA projects more to the front, more in your face, if you will. Solo instruments in these works stand out more clearly in character from the mlange of sound around them and dynamic swings are surprisingly instantaneous. The amplifier strikes a visual resemblance to the ST-10, and while especially the amplifiers bass and overall solidity are strongly reminiscent of the ST-10, at the same time, I hear a new level of linearity, refinement, and low-level detail. summithifiusa.com, Associated Equipment If you are asking for an ideal affordable preamp for the EVO-STA then I would say the AGD Master 1. I have not heard the TB200 but the Kora TB140 has also surprised me. Holo Audio Serene KTE, Short update: I got the chance from Schelto to try the Kora TB200 and got blown away. And also a thank you for following up on my suggestion to put two AMG-STAs in dual mode to the test. If desired, you can always add a second unit. With this interlink, the Evolution STAs treble gains more fluidity and becomes a little bit airier while the cables slightly leaner yet highly articulate bass works well with the amps inherent solidity and fullness. EVO STA to arrive soon. No sex appeal here.

While this will probably not be ideal for the amplifier, it does provide the ideal setup to compare the two amplifiers. providing a truthful sonic snapshot of upstream components. Then I heard the NuPrime ST-10 using proprietary class-D circuitry and it changed everything. But thats not exactly how it went down. Rather than adding any kind of sweet sauce, the Evolution STA simply relays the music as unedited as it can. The Evolution STAs bass really is sublime and reminiscent of that of theAnalog Domain M75, AVM Ovation A8.3, andAnthem STR. The Tip section is +12V, the bottom Sleeve section is GND, and the middle Ring section is not used. 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. Very few manufacturers could design a 1M input impedance without adversely affecting noise and stability, and those amplifiers are priced many times higher. Thats always been what the high end is about. What preamp are you using? 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. Is that your opinion as well ? 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.

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. This load has proven to be problematic for some Class D amplifiers due to its capacitive impedance and 2-ohm minimum through the upper octaves. Pulling out theAMG-STAfor a final direct comparison, it becomes clear that this amp is quite different still. Transients were naturalistic (more on this later), and theres was no indication of etch or grain in the upper octaves 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. I double-checked but I dont see an error. While it is less expressive and more polite, the AMG-STA does have very nice flow and the PRaT also remains pretty good. In this context the NuPrime was able to generate a panoramic soundstage and believable depth perspective. 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. Wherever they were used, they were like chameleons, always refrained from editorializing the sound.

Accessories: Sound Application CF-X & TT-7 power line conditioners, Tags: 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. In fact, the soundstage was exceptionally transparent, wide, and deep, with believable image focus. As a consequence, it simply reflected the character of upstream components. Moreover, while a nice dose of rich juiciness can be utterly seductive for a couple of songs, when an amplifier injects all the music with the same flavor I tend to get bored with it after a while. Prior to starting my serious listening sessions, I made sure to leave the amp powered on for several days, and even before this, the importer also used it at home for two weeks meaning that the unit should be properly run in. 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.
