Okay, Classe CA 2200 or and Ayre V -5xe amps

TPpreaves....I did and I have. I had a Model 5 for about 14 years or so ...then I went to 501's and was not impressed with those at all....then a Model 112 - great amp, but not enough juice to move the Avalon's at 6 ohms and 86 efficiency. The bigger Rowlands are just that too big and out of my price range

Well, besides Ayre that you originally mentioned, and Rowland that was suggested, I would also recommend Pass Labs. They make solid state amps that are built like a tank and sound very good. They make a variety of models, in a range of power outputs, including both stereo as well as monoblock designs. They come in a variety of full Class "A" and Class A/B designs. They tend to run pretty warm to very hot. (So a large and/or well ventilated room is a requirement.)

Now, if you are willing to go with a hybrid design, (i.e. with solid state input and output stages, but with a tube driver stage, that has only one 6922 tube per amp), I highly recommend the Lamm series of hybrid designs.

They make two types of hybrid designs:

The first is a 100 or 110 wpc full class "A" design, (the M1.1 or its predecessor, the M1.2 Reference). These will drive most any speaker, and sound incredible. But they do run hot as they run all out, all of the time, so they will heat up a room several degrees.

The second is a 200 or 220 wpc Class A/B design, which is heavily biased into class "A", (the M2.1 or its predecessor, the M2.2). These will drive virtually any speaker design, and sound very nearly as incredible as the full class "A" version. (The full class "A" version is just a touch sweeter sounding.) These run very warm, and will warm up a room a few degrees, but they will not burn your hand if touched.

(Note: the M1.1 and the M2.1 are very slightly dark sounding in comparison to their predecessors, the M1.2 and M2.2. The later two amps are among the finest amplifiers I have ever heard. They are powerful, with outstanding bass control, a well extended and sweet treble response, and a touch of that old tube magic in the mid-range. The only high powered amplifier I have heard that rivals them is the VAC Phi 300, albeit it has different strengths and weaknesses.)

FYI, I own the Lamm M2.1, (and hope someday to upgrade to the M2.2), and have found that using the Nordost Valhalla speaker cables has mitigated the aforementioned slight dark sound for the most part. Used, the M1.1 and M2.1 run around $6-7K, while the current designs, the M1.2 and M2.2, tend to run around $8-10K used, and $22K new.

I am not sure of your budget, so it might help to let us know what that is.

My two cents worth anyway.
Good Luck in your search!

Tried the Classe 2200 with Avalon Diamond & OPus Cerimique. The pass x350.5 is better in most ways. Did not try the ayre. Lamm is good too

I tried the V-5xe in my system a few years back agains my then McIntosh MC352 and ended up getting a MC402. I found the Ayre to be very musical but seemed to come out a little aggressive in the highs. I have never tried the Classe' but have heard them in the store against McIntosh and think that the Classe' offers a great sound. I really didn't find it to excel in performance over the Mc so have stayed with Mc. But as far as model of Classe' I appologize that I can't remember. It was in the same price range as the 402 is all I can share. I will add that Ayre does provide excellant service, by experience I have had with my C5xe CDP.

About Ayre, I also find their sound to be a bit aggressive for my prefs. I heard them 4 years in a row at RMAF and AYRE electronics, including flagships MX-R and KX-R remains not of my liking.

As mentioned in a private msg to Gary, the JRDG 501 all by themselves can sound a little matter of fact. . . a pair of external JRDG PC-1 rectifier/conditioners will make them sing, but they will add significantly to the cost.

Within Gary's budget and within the classic JRDG line, one device to look at is, to all reports, the Model 8 stereo, frequently seen on Audiogon for under $5K. Several people I spoke to believe Model 8 may have been at the pinnacle of Rowland's classic lineup.

During the last RMAF I was very taken by the sound of a system which used a Belles stereo amplifier--more than likely the 350A. Did not A/B it to my own JRDG 312, but it gave me the same sense of musical ease, revealing low level detail, and grip on speakers. . . I suspect it is definitely an amp to look into. . . I just seen there is a unit on Audiogon for just under $5K offered by Hollywood Sound.

Last but not least, Gamut is also a fabulous brand of amps. The reference level monoblocks featured at RMAF were spectacular. have unfortunately not heard their stereo version, nor have I compared them directly with my JRDG 312.
