Hi Steve
Yes, you're right, I had a used one back in 2009. I think I paid about £1200.
Here's what I wrote about it a few years ago, slightly updated.
"I had the Chord CPM 2600 integrated amp and kept it for quite a few months - quite a long time for me and a sure sign that I enjoyed its sound.
Very bright to start with (it had been stored for months in a freezing loft, maybe some components needed to warm up and settle in?) it soon settled down to a presentation just slightly on the mellow and easy to live with side of the fence. Quite detailed and transparent.
The volume control played up a bit - at least the remote control aspect, as it often failed to turn properly - very frustrating and I was not pleased at the amount that Chord charged me to fix what they admitted was a design fault as this was quite a common cause of returns.
But nonetheless a fine sounding bit of kit, imo."
