Bryston or Pass Labs

Ok, why are you looking only at those two amps?

You have a great set of speakers which certainly do not match your current Adcom amp. The new cube series Bryston is very good. Owned a 14sst myself at one time but I don't know if it is at the level of the Pass gear. If you have a chance to listen with your speakers that would be best. Also strongly agree with previous comments on upgrade to better speaker and power cords. Best wishes.

you own very nice gear, especially, the CJ GAT. There are many audiophiles
who pair a Pass Labs amp w/ the GAT as they are sonic matches. The Bryston could possibly mate well w/ the GAT? At this level of price and performance it is best to audition both products. Keep me posted, I am a big CJ fan. Happy Listening!

I have a CJ ET-3 SE hooked up to a Bryston 2.5 SST2 and it makes an excellent combo. Plenty of detail and no harshness.

linnlingo- the CJ ET-3SE is a very fine pre-amp, especially, at its price-point in the used/demo marketplace.
Happy Listening!
