As good as the reviews say, maybe better. Dead silent background, great dynamics, neutral timbre, fantastic DAC section.

Many stellar reviews online, such as:
The Absolute Sound (Product Of The Year)
"...when you consider the NuPrime IDA-16 has an advanced DAC built in, which will play virtually any digital recording available today, it’ s an even better value. Of course, if it didn’ t sound good, it wouldn’ t be a good value, no matter how low the price was, but it sounds excellent...The NuPrime IDA-16 DAC/amplifier along with the KEF LS50 speakers made a system that, if you’ll pardon a tired reviewer cliché, punched far above its weight. So to return to the question left open in the first paragraph: Yes, the NuPrime IDA-16 DAC/amplifier can indeed be called a bargain. Highly recommended...", - Vade Forrester, editor

Against the NuPrime’ s jet-black backgrounds, all of the dynamics of my recordings were present at all volume levels, making the IDA-16 one of the few amps I have enjoyed for late-night listening... IDA-16 is an exemplary integrated amp-DAC with rock-solid imaging, transparent sound, and tight control of bass...", - Vince Hanada, editor
