Jeff Rowland 2 or Classe 25 for Avalon Eclipse

Aspac, there are *many* amplifiers available in your price range that would drive your speakers quite well. If I was making the purchase, I would err on the side of having plenty of power, 150 watts/ch. or more should do nicely.

I have a 5.1 surround sound system and was very happy with the Butler TDB-5150 that I used to drive my Gallo Reference Series speakers. It had 5 channels with 150 watts.channel. Additionally, it is a "hybrid" amp - it uses both tubes and MOSFETS.

Butler also has a 2-channel model called the TDB-2250 with 250 watts/channel. All of the Butler amps are *very* well-made and sound very good. A brand new one will cost you about $2995. Here is a link for it:

Another very fine amp is a new offering from Emotiva.com, an internet-direct company. Their power amps are very well-built (with a 5-year warranty!), use very good parts, and sound very, very good for what they cost.

Their newest amp is called the XPA-1L. It is a mono-block design, it is a single-channel amp, you need 2 for stereo. It has 250 watts into 8 ohms and 500 watts into 4 ohms - very powerful. In addition, it is a combined Class-A and Class-AB amp and runs fully-balanced. This means that for the 1st 35 watts of output, it runs in pure Class-A mode. Many folks here will tell you that Class-A is the best-sounding solid state type of amp. Let your ears be the judge.

Anyway, these are very good amps and cost only $699 each with free shipping. And all Emotiva products have a 30-day in-home trial period and come with a 5-year parts/labor warranty. 2 of these would cost you $1400 - it would be almost impossible to find a better value on the market today...

Good Luck!

Thank you all for support, All I need is the amp match well with my speakers, so pls tell me which one will you choose?

I would choose the JRDG Model 2, it would work fine with the Avalon's in my room with my tastes. However, I do not know how big your room is or how loud you listen.

I have a Classe 15 in my secondary system. I also heard the Classe 25 many times over the last 15 years. The Classe house sound is a little dark sounding. If you don't like bright, this is an amp to consider. I am running my Classe 15 amp with a tube preamp and Vandersteen 2CE speakers. It is mostly used for background music while I am on my computer, but it is a very musical sound.

Keep in mind the Classe 25 amp is at least 16-17 years old and if it were I, I would probably think about replacing the caps if they are leaking. The Classe is 250w a channel at 8 ohms, 500w at 4 ohms and 1000 watts per channel at 2 ohms. It is perfectly stable down to 2 ohms. My Classe 15 amp has been 100% trouble free. The power supply in the 25 is very overbuilt as is the heat sinking.

I know nothing about the Rowland amp.

Both amps sound warm and musical. But a sharp individual focus they both do not have. Avalon ( which I sold for over 6 years) can give a deep and wide stage. But misses the sharp individual focus of instruments and voices. These amps have the same properties as the speakers. At the end you miss.......yess the individual focus. For me it is that simple! Like 1 and 1 is 2.
