I recently acquired a Nuprime IDA16 and I am very impressed with it. I am using it with Amphion Argon 1 speakers in my office. It is still improving, but I agree, it is a remarkable amp, and a remarkable bargain. I'm not thrilled with the remote, or the front panel buttons, but in terms of sound quality. it is very, very strong.
And on topic, it is nowhere near metallic, or fatiguing. In fact, it is already a much more .... easy, amp than the Hegel amps I've listened to. I don't understand any of the technical stuff, but my class D amps, the Nuprime and my Devialet 220 Pro, are outstanding. Dandy? Yes.
