Hi Dan,
We must have similar tastes, I've owned or certainly considered purchasing many components in your system.

Coincident had both single chassis 845 (mine) and mono block version for a short time, both no longer available. Perhaps they'll come back some day.

I do need to upgrade my vinyl, looking seriously at AT art9xa.

Thanks for the positive comments, hope you continue to enjoy your system.



@jaytor I modified Crites AA crossovers, first to A crossovers, which meant getting rid of tweeter protection, mods proceeded from that.

Yep, the Acme 300b just starting to really come along, at 80 hours now, starting to bloom, fill out, relax. I can tell these major upgrade from the Shuguang Black Treasure. Acme's would be real contender for your new 300B amps.


I'm using Jelco TK850L with Denon 103R. I've been concentrating on digital side of system now for a couple years, analog has fallen behind, looking at Lyra Delos, Audio Technica  Art9xa, Soundsmith, some others to bring up analog to higher level.

300B tubes used Shuguang Black Treasure and Psvane Acme, Acme play on much higher plane. Still burning in the Acme, so final analysis waits, so far seem like keepers. I may post mini review on one of the existing 300b threads here.

@jond The amps are that much better with Acme, reaching potential with nice power tubes. 300b amp now ahead of Coincident 845, will need top flight 845 tubes to compete at this point.
