NuPrime IDA-8 – 1250 Euro
NuPrime puts a very compact, but very nicely built amplifier in the market with the IDA-8. The IDA-8 places particular focus on digital inputs: there is one analog input and four digital ones: usb A, usb B, optical and coaxial. As a bonus, in addition to the speaker outputs, we see a set for a subwoofer.
The class D amplifier was developed in-house and delivers 100 watts in both 8 and 4 Ohms. Our measurements are pretty close to that: 82 watts into 8 Ohms (0.5% THD), but then again 110 watts into 4 Ohms (0.7% THD). We also saw 115 in one measurement… Let’s say we can average that to 100 watts… shall we?
We received the NuPrime brand new. So, we put the amplifier through its paces for two days straight before sitting down to listen to it properly. The first day was the biggest difference: it went from quite rough to a lot less sharp. Also the bass end improved considerably. So keep that in mind.
The reproduction of the NuPrime is energetic, generous across the spectrum and well in focus. What we like is that the mid bass also has body. That gives a pleasant glow. Something the Roksan possesses less. That one comes across as a bit colder.
What we did not expect is how relaxed this amplifier can play. Class D is always associated with tight, cold and restless. But like the Cyrus, this NuPrime is not that at all. Across the board we hear control and a pleasant balance.
What is striking about this NuPrime is that the intonation of vocals is very accurate. We can almost hear what exactly is meant emotionally. In doing so, the whole thing feels rhythmic and smooth without being too attention-grabbing…. yes… this is also a fine little amplifier.
The imaging is similar to the Atoll in a way. We hear the voice well framed, just above the Focals. The NuPrime doesn’t put down excessive space. Like the Atoll, it presents a stage. Here and there we hear effects to the left and right of us, but this is not an immediate “space monster”. Do not confuse it with a image that sticks to the speakers! Because that is definately not the case!
NuPrime is not something we’ve had in house before. It was honestly the second experience with an amplifier from this brand for your author. The measurements look good in terms of power and stability of delivery (almost spot on according to spec). The noise floor is slightly higher from some other amplifiers (-100dB compared to -120dB). However, it does stay pretty quiet across the spectrum; which is pretty even.
THD at 1 watt is 0.11% maximum. At 10 watts it does go up rapidly towards 0.71%. Both at 5500 Hz. The frequency response is somewhat similar to that of the Leak and Rega Brio, however, the NuPrime is much straighter towards 30 kHz.
