Hi JB - Sorry, I just can't seem to remember to check Audiogon more often for messages.
I can't say I was disatified with the Cambridge, but had the feeling it just wasn't up to the quality of the rest of my system. I talk more about this in a "review" I posted in the Audio Aslyum.
Here's a link to the review:

I'm not an expert at doing reviews or describing what I hear, but have loads of opinions! So if you have any questions about any if it, please use email to [email protected]
I'll probably sell the 640C soon - it has one "prob" and that is when first turned on the display is supposed to say "no disc" and it says "no dis8."
Once warmed up a few minutes the "8" turns to a "c" and I'd not send it back to get something like that fixed as much as stuff like that bugs me.
There must be some kind of glitch "electrical signal" getting to the display when first turned on.
I don't think it affects the sound at all and I'm not trying to sell it to you, but a couple of people asked if there's anything wrong with the one I have.
