best integrated amp.

i have seen a mf nuvista 800 lately for $7500 a serious amp for the cash .12k new stereophile raved over it .

Agree with the Hegel H300, have had mine for 2 years and it steps up to new levels depending on the speakers. I just demoed with Sopra No.2 and its the best the Hegel ever sounded. I like an Integrated that has the next gear when required. I suppose the Hegel didn't perform any better the Sopra's simply let you hear what the Hegel can actually deliver. That to me is a good investment piece.

I'd think you want to listen to the Primaluna Dialogue HP.  I have the amp, not the integrated, and it sounds amazing.  I think the integrated is in the low $4K range.

Impossible question to accurately answer. Synergy will make or break any individual component.
