The Coda 11 is indeed a discontinued model. I had one back in the late 90s, so you can see how old it is. It’s a great sounding amp, but I’d steer clear of one unless you want to do at least a recap on it.
Amplifier recommendation
I have acquire a Acurus A150 amplifier a few month ago that powered a few speakers. They are my DIY Dayton speakers( was my first speakers for a while), Paradigm Mini Monitor v3 and now the new acquire Triangle BR03. The Triangle sound amazing with the A150 but I want to try another amp with similar specs. The two I was interested is the Bryston 3B SST or the Coda Model 11. The preamp is a Rotel RC995 which has balanced output to as well as RCA.
