I know about ARC, but its a problem - its software based, and I don’t think the EQ algorithms are as good as Weiss. But, whats important is I need a hardware unit which can run on the signal regardless of the source.
I should add, although I mentioned audiophile grade, its for a pro audio studio in a treated room. But the problem is the pro audio crowd room equalization (i think) is not extremely great sounding.. I thought hi-fi might have some really high end products.
