What preamp will you be using? Those are all great amps so I’d look for synergy with your pre. Earlier gen Raidho’s pair exceptionally well with Aavik amplification as both were designed by Michael Borresen. Your TD’s were designed by Benno Meldgaard after Borresen left Raidho but I suspect the pairing is still a good one.
Coda’s roots go back to Threshold which was a Nelson Pass company so the Coda and Pass amps may sound more alike than different. I’ve heard Pass equipment but not Coda, so don’t take that as gospel though.
If you go with Constellation, please post your impressions as that’s something I’ve considered to match with my Raidho’s but haven’t listened too yet. I’m using Devialet amplification and really enjoy the match up.
