Coda CSiB is a really good integrated. I had the V1 version which is 150/300/600w per channel into 8/4/2. The CSiB drove my Wilson Sabrina no issues.
I am using Boulder 866 now. I would say both amps are excellent and it comes down to personal preference and what works best with your setup.
Coda is more forward but in a good way without being harsh, it has really nice crystal clear mids and sweet highs with fast bass. Boulder is slightly bigger and warmer sounding and sets everything a bit further back into the soundstage.
