I don't know what chips it uses, but the Arion Audio S500 amp fits what you want in every regard. I have had it for 5 years now, and I couldn't be happier.
what's a good Gan / Class D option under 3k? Nilai or Ncorex500?
I was on the VTV amplifier page and a bit overwhelmed by all the options
I like a fast energetic amp with lots of power
I want something that I can use as a tool to test a variety of different speakers in 2 channel application
The NcoreX500 modules appear to be just about right but then I noticed both VTV and Deercreek audio carry the Nilai modules which are apparently even better?
any suggestions/advice?
