Infinity Renaissance 90 Piano Black

thank you 

Adcom 555 is just fine.

I own a couple of pairs of vintage Infinitys. Magicmarsky (Dr. Marks) is the man! Also, the Infinity user forum at the AudioKarma site is a GREAT resource. Ask there and you will receive....

Good luck and "Infinitys Forever!"

George i run an ADCOM 555

I agree with sunshdw it has enough wattage at 200w into 8ohm, but they don’t really muscle it into 4ohms only adding another 100w, the 2ohm figure would be a bit worse again and blew it’s fuses when ask to do it.
And the Ren 90’s hits 2ohms EPDR and lower from what I’ve been told by a tester of them.
They’d like a more Krell early amps of 200w or 300watters, which have more low impedance balls than the Adcom

Cheers George

I may know of someone who has a spare or two. I picked up a few parts for mine recently(Ran 80's and 90's). Do you still need one?
