Audio Research Corporation ARC Reference 600

Does anyone have any opinion about manley amps? The neo-classic 250's or 500's? Do they measure up to ARC, or VTL?

I just looked up the specs on the Klipsch KLF 30 speakers. Sensitivity is a very high 102 db. Unless you have a huge room and listen at ear-splitting levels, I think you would be hard pressed to stress a good 75 wpc amplifier such as the REf 75. Most of the time you will be listening at less than 1 watt.

Agree with Mabonn. If you think you may change speakers at any time in the near future, you may want to step up to the Ref 150 now, the Ref 75's bigger brother. Anything more than the Ref 150 at this time is like swatting a fly with a 1000 ton press. Btw, I've seen some preowned Ref 150s listed for a decent price.

Aside from power overkill, I would challenge point how the Ref 600 sounds compared to ARC's current Ref offerings. There's been a lot of water under the bridge since the Ref 600 was at the top of the ARC food chain.

Cheers,

I have owned many ARC and the Reference 300 is their best! The problem with ARC is that once aged, the circuit board will short circuit and BANG!*"|@# ... total up needed!

Let me also add that since you have speakers that have a 102dB sensitivity @ 1W 1 meter, noise becomes more of an issue. The Ref75 should be quiet enough, but what kind of preamp are you using? The s/n ratio of some tube preamps would be low enough to cause a definite backround hiss through your speakers which you may find objectionable. This noise can interfere with imaging, front to back depth, and low level detail. Just thought I would throw that in.
