I liked the CSiB V1 a lot but preferred the KRELL K-300i integrated more (I owned both last year). I sold both and now have the CODA #8 and the KRELL 175XD amps with the CODA 07x preamp. I liked the 2 integrated so much that I wanted to step up a bit higher with the separates.
If you want to try something a little more daring, try a Benchmark LA4 ($2500) with a CODA #8 or with a new KRELL XD amp. I love that combo. If I ever get the CODA #16 amp, I am using it with the LA4 preamp, not the 07x which I also like a lot.
