stereo5 I have not had the pleasure of hearing the 2550, but did hear the 2300 and then its successor, the 2500. What I loved about the 2500 was it had the "beautiful, golden" cj sound of the 2300 but they had significantly improved the bass punch and depth. I would have bought that amp right then and there if I didn’t already have a fine power amp for my system.
There is a special something about cj solid state amps. They manage that tube-like lushness but with authoritative bass. I had looked at cj’s website recently and I think I would go your route rather than the SE version if the cj house sound is what you are after. I have also heard the Goldenear 1s on an occasion and found them very clean clear transducers. The references must really be something. Congrats!
Please let us know how everything works together. Audio Nirvana?
