This may sound a bit silly but why are so many

I'm having the opposite problem. Looking for a specific (which will remain unspecified) tube amp. Why so few?

Frank,

Here's the link:

Christmas morning is better than Christmas afternoon. AudioGon allows the buy/sell/buy thrill to trickle downward, allowing more to chase a high of high-fidelity. As with other things, the chase and expectation is often the best part. Don't buy a Cadillac and a gun on the same day because the expectation of happiness can turn quickly.

Thanks for the link.That answers my original post.

What I didn't like about the ARC REF40 was that it's sound was just too tuby, it brought back memories of the ARC of old. Other than that it was OK for the price.
