Mcintosh c48 vs classe cp800

I plan to buy one of these 2 dac preamp. I wonder if anyone has had the chance to compare. Which one you prefer and why?

Also for those who are only listening one of the two models i would like to have your impression.

Thank you
I owned a C48 awhile back, and absolutely loved it. I loved the simplicity of the preamp and it sounded great to me. Unfortunately, an un-expected financial problem arose and I had to part with it. BUT, it's on my "buy again" list sometime in the future. BTW, I've owned many Mac preamps, and this one was the best!!
