Audio Research Corporation ARC Reference 600

what are you after? if it is sound quality, using huge high powered amplifiers from ANY company will be a step BACK in sound quality. If you were using huge and inefficient speakers that would take advantage of all of that extra power, that would be a different story. But with your speakers, high powered amps would sound less good than one with less tubes and circuitry in the signal path. A ref 75 would sound MUCH better than even a ref 150, or any of their higher powered monoblocks.

You guys are awesome. I am gathering that a ref stereo 75 is better than monos? Or are you referring to two stereo 75's as mono blocks?

Rich,

Don't think the Ref 75 can be used as a mono blocks.

Given the high sensitivity of your speakers, the Ref 75 should have more than enough muscle. I only mention the Ref 150 if you think you may change out your speakers for less efficient jobs. Otherwise, the Ref 75 is at the top of the audiophile food chain.

Good luck and let us know what you decide upon.

Cheers,

Bruce

I am leaning heavily towards a REF 75. How could you go wrong? I just though separates were considered better than a one box deal. But throughout this thread, the REF 75 seems to be so loved. It's always nice buying something that you know you'd have no problem selling if and when I am ever done with it.

You should audition a REF75 in your system if you have an ARC dealer nearby. Then you will be able to make an informed purchase decision.
Based on sonic merits alone, the REF75 is at the top of the ARC amp line (now and past).
Just my 2 cents.
