Mine is just the run of the mill, garden variety, plain vanilla version that was bought in '06, serial number 015. It has been used off and on for the last 10 years, never causing any issues. Used with all kinds of amps, solid state and tube. Currently, it's in duty driving a pair of stereo ss amps(different makes, different power), that in turn are driving a pair of AR 3's, and a pair of AR 3a's, that are stacked. The sound is nothing short of outstanding. Truth in advertising fits here. This preamp can truly drive anything without any issues and sounds great doing it.

I've seen a lot of gear come and go over the last 10 years, but luckily I've resisted any urge to sell the CSP2. I suspect that will be the case for at least the next 10 years.

What a small world, I’m currently the new and 3rd owner of your CSP2 serial#015. It’s still running strong and a true delight inmy current system. I love the versatility and never before had this much control of my amplifiers. What is old is new again, at least to me! Cheers.
