Input Requested on Possible Amp Change


I would appreciate some input on whether it's a good idea to change amps. I have some Cerious Technologies React 2 speakers, which I really like. They are rated at 88db/1m/1m, 3.2ohms at 122Mhz...FWIW.

After I acquired the React 2's, I then acquired a Cary Audio SLP 98p tube preamp which to me was an audible upgrade from my McCormack RLD SS preamp, although it may be just the gain characteristics. Whatever I like it a lot.

After I acquired the 98, although I was thinking tubes...the 88db and a very good deal pushed me to acquire a pair of Cary Audio monster SS mono amps, CAD 500's. I've never turned them above 4, and that was LOUD! These replaced a McCormack DNA125 which also could get loud.

Because I like the tube preamp so much, I've been thinking tubes again for amplification and I'm trying to stay under $4K. I live in a place where most folks think Best Buy is the bomb so auditions with my speakers are out.

I guess my question is...will 75/80 watts each from some tube mono amps do the job with my React 2's or am I nuts not to stick with the Cary SS amps?

I sit about 3 meters from my speakers, turn it up sometimes for blues rock, and listen to mostly jazz and female vocalists at normal levels the rest of the time. This could move to 5 meters someday but probably not.

I am looking at some used Quad ii-80's (80w RMS each) and some used Atma-sphere MC-60's (75w with autoformers).

PS I tried the amp forum and although I know ohm's law, that stuff still makes my eyes glaze over. Thanks in advance for your time.

Never heard your speakers but the Atma M-60s and the VAC 30/30 and 70/70 are all special amps. Talk to Ralph at Atmasphere- he's probably heard his amps w your speakers or knows someone who has and he is a very straight shooter. Both are excellent products w great support and should come in right in your price range. If your speakers were designed to be used w tubes, my prediction is that once you hear them w a good tube amp, you'll never go back.
Even though a watt is a watt is a watt, you will definitely find that you will need less power with tubes IF (big if) your speakers were "voiced"/designed to be tube-friendly. For example, on paper Wilson and Soundlab speakers don't have the efficiency/sensitivity that you would think would work well w tubes, but many people are very happy using tubes,including the Atmasphere OTLs.
