Maby just any speaker you have tried.

I did not say NIGC drives any speaker.
I indeed said it didn't have problem to drive any speaker I tried. I had only one or two comments from customers who were not happy with the amp driving their speakers.
I tried Zobel again yesterday, on Altecs, and it messes the sound tremenously. I used regular parts for that network (Dale and Wima). Maybe better parts would sound different.
It's been originally suggested that it's better to have lower supply voltage for 4 ohm speakers. It is indeed case if you want to push the amp for the max power, but for regular listening levels (90db speakers) I observed that the amp sounds better with higher voltages. I wouldn't go lower than 34V on rails with ANY impedance speaker.
