I have been using my new CODA CSi Integrated for about 2 months, and I believe that it represents a true "High End" marriage between amp & preamp with all the modern remote control features. This new CSi is the next generation of the Unison Ultra, but with upgrades to numerous components. At 220 WPC, it drives my Tyler Woodmere 2's with ease and grace. Specifically new in this latest version is the new Burr-Brown controller (less distortion than the previous version) and a MOSFET voltage gain stage, which has reportedly given it slightly smoother (more tube-like) sonics. Also Black Gate caps, etc.
We haven't heard much from CODA lately, as their main production focus has been on the European market, who seem to keep them busy buying all that CODA can produce. But they are still hard at work in development and production, and they will fabricate American orders whenever requested.
I am planning to listen for another couple of months, and then submit some type of review based upon my experiences.
