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.

Zd542...Thanks again for your input. I will check out the VAC amps. What do you think of Carver's recent tube amps? They look great, certainly have watts to spare, and the review's are pretty positive. People tend to love him or hate him but uh, who cares? Is his latest iron worthy or not? I'm leaning toward moving my budget north anyway because I really do want to buy and be done, but of course that brings more choices into the mix. It's a fun hobby and all but I've got bigger fish to fry and I'm not getting any younger. My rig is already uh, adequate, as Aston Martin likes to say about their cars' horsepower.

And yeah, I know Bob G. A mutual friend who had some CT React 1 speakers that sound spectacular put me in touch with him several years ago when my 30 year old Sansui finally bought the farm. I bought an SS amp and some prototype speakers from him that he built somewhere in the transition form UA to CT which look a bit like UA Cerious 7's. A few years later I'm surfing Agon and I see he's selling some CT React 2's at a price I could actually afford so I call him and boom, there mine. He actually delivered and set them up in my house since he was taking a class of some kind about 60 miles away. I haven't talked to him about my current tube amp obsession but I will before I pull the trigger. From talking to him in the past, I get the impression he's not the world's biggest tube fan, but I may be wrong. And yeah, I have speakers out the wazoo!

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.

Swampwalker...thanks for the reply. As I've mentioned my only issue is that the amps in my system produce enough volume with my somewhat less efficient than average, but great sounding speakers; so I can hear all the detail. My ears may be a little worn out but for me, it takes a certain amount of volume to make the music really sing. I am looking at all the amps you mentioned and a few more. The worse thing that can happen is I will end up with a great sounding amp.

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.

There have been good tube amplifier recommendations offered here. I have to say that if a good condition VAC REN 30/30 or 70/70 become available give these amplifiers considerable thought. 300b tubes in a push pull circuit,stout power supply and excellent output transformers. These amplifiers make music and are special.
Good Luck,
