@jbhiller I don't know about ASR or the rest, you may have mixed me up with another poster.
I owned the Coda while I was on a speaker binge last year. I wanted to try a few speakers _CW4, Spendor D7 and Gershman. I found the Coda to be neutral, textured without being bright, had great musical flow (PRAT) and large scale sound while still being subtle. Great transparency. Warmish or neutral without loss of detail, fast without the shiver. In my opinion it was better than an el34 and el84 amps I tried or heard.
I'm not crazy about the front panel of the CSIB, mainly the fact that all the lights stay on when you power the amp down, but it's an amp that I would own again and I would even say I regret selling at times. I shipped in from New England to California (where it seems most gear goes) and the volume display and the bottom plate were damaged in transit. It's heavy and packaged well but shipping is horrible these days. Coda fixed the issued for around $275 (very reasonable).
I've never heard the Pass Labs. I wish they had a presence in the northeastern part of the US.
