Here are the notable statements from the review:
“With IDA-8, I not only could the ear locate the cymbal hits around the drum kit but there was an appreciable amount of space for cymbal reverb tails giving this low-key instrument a larger presence. As for the adjacent drums? They performed very well indeed…

Any subtle detail made it to the ear intact. There was no smudging or blurring of that information. The sense of clarity was high indeed…

“…The IDA-8 conveyed the music’s richly woven textures as well as its individual parts. Soundstaging was deeper and wider than I expected for an amp in this price category, with precise instrumental placement. Background noise was also shockingly low; the IDA-8 boasts an impressive 95dB signal-to-noise ratio…
…the IDA-8 is a winner, and a force to be reckoned with in its category (and beyond it)…it brought warmth to its clean and clearly resolved presentation of digital sources to…Though a touch dark in character (à la Class D), it delivers substance and warmth with A well-conceived Class A/Class D hybrid that doesn’t want for power or clarity, the IDA-8 ought to find itself on the audition short list of a wide range of hi-fi hobbyists, from newbies to more experienced audiophiles…”

“…When I’d hooked up the Definitive Technology StudioMonitor 45 speakers to the IDA-8 and begun playing music, I realized that the NuPrime was unlike any other entry-level amplifier I’d ever had in my system. Everything immediately sounded more precise and controlled…
… the little IDA-8 sounded so refined and powerful that I soon decided that, to get a true measure of its sound, I needed to move it into my reference system. In that system I had a variety of high-end but still high-value speakers to use with the NuPrime IDA-8: the KEF R900, Definitive Technology Mythos ST-L, and GoldenEar Technology Triton Five. Even with those floorstanders, the IDA-8 was able to tightly control the low frequencies in Lorde’s bass-laden Pure Heroine (24/48 FLAC, Lava Music/Republic). The IDA-8’s midrange was also something special: exceedingly clean but very full, reproducing voices with clarity and presence while also providing their full weight and body. With the IDA-8, I felt I was hearing everything in Susan Wong’s 511 (24/96 FLAC, Evosound) — not something that I think I have ever said before about an integrated amp costing under $1000…The NuPrime’s sublime midrange allowed voices to float effortlessly in mid-air…
…It sounds fantastic, has plenty of power to drive any reasonably efficient loudspeaker to room-filling levels, it’s compact, and, best of all, it costs less than $1000…the NuPrime IDA-8 was so good that it seemed almost a shame to extract it from my reference rig and reinstall it in my second system, where it will remain as my new budget reference amplifier. It’s one of the best deals available in audio today…”
