Infinity Renaissance 90


After owning these for years they continue to amaze me. A dear friend let me try a pair of Primaluna Prologe 6 mono Amps to try out and possibly purchase. With these on the top end and a Krell Fpb-400cx on the bottom end it’s a truly amazing sound. I am currently evaluating the Amps rotating between El-34 tubes and Kt-120 tubes. I must say I love the Primalunas. Very well built and a bargain price. Folks if you ever have a chance to obtain a pair of the 90’s you will not be disappointed.

Definitely one of Infinity’s better speakers that are still manageable in size.

Enjoy,

I have to 2nd your observation.  Bought mine around 2000 and then a spare pair of EMIT's from Infinity just in case, then a spare pair of 90's just in case.  Only thing I have done is replace the foam in the rear port and wax them a few times. 
Powered with a Krell 300cx & KCT pre, I am in bliss.  They are an amazing asset to my system. 
Good luck with your power change.  Should be fun indeed.

I love the Ren 90's, the best I heard them was bi-amped with two big solid state Krells. 

The Ren 90’s have a load presented to the amp very much like the Kappa 9’s (I was told by Trevor who measured this graph linked below).

Saying that to get the very best out of them, your Krell on the bottom is the right amp to drive that low impedance, but I think the upper mids around 5khz which is the same kind of nasty load as the low bass, and maybe an amp more like the Krell (a current pusher), only smaller (as you wouldn’t need 400w) would do better up there also for the mids and highs.
