Anyone have Coincident Frankenstein amps?

Afc,
These amps are very good straight out of the box and will in time make the transition to superb reproducers of music. Remain patient my friend, you`re going to be quite pleased.

I totally agree.Be patient any enjoy the fun in breaking these special amps that are in my opinion, one of the finest amplifiers available.
As amazing as they are, their performance can be enhanced by the addition of the Coincident Statement Line Stage I had in my system for two weeks a few month ago. The linestage is totally transparent so it does not diminish those qualities of the Franks, but it adds a sense of impact and authority that makes them seem like they are now 50 watts instead of 8. The combination of those 2 units brings about an incredible enhancement in the musical experience.

Are yours a bit grainy on warm up? For the first 15 minutes of listening or so, they seem a bit dirty- but once warm, they're crystal clear. It's an interesting transition from the Franks to the MastersounD. The former is exquisitely detailed- you can hear picks moving over strings, and everything seems right there. The MastersounD has WAY more grunt- it can overpower the solid state Rowland without breaking a sweat. I was a bit surprised at how much more headroom seems available with the 845 amp than there is with the Franks. Yet, the MastersounD retains a lot of the clarity of the Franks. Each have their strengths.

Tony,
The Mastersound 845 is an exceptionally good amp and of course in your case fully broken in. The 300b won`t match the power of a 845 tube. You need hours of break in for the amp and 300b treasure tubes before they reveal their wonderful capabilities. If you think the Frankenstein is detailed and transparent now, you`ve heard nothing yet!

Very true. Also very true about comparing a 300B tube to the output one gets from an 845 tube. But I have been just a bit surprised by the relative headroom the amps seem to have....the MastersounD seems to have a LOT more- more than I had expected. I think a lot of it has to do with the music you listen to as well. Jazz, classical (some of it), seems like the Franks win with their accuracy and detail. You want to crank it up with some rock and roll, or even the 1812 Overture, the MastersounD becomes boss. The 300B's have that delicacy in the mids that is really, really nice....but the 845 tube isn't that inferior to it. I'm fortunate. Have the option of going back and forth between top notch SET amps based on different output tubes. It's a fun trial and error routine. Also need to nab some better IC's to run with the Franks- the old MIT's I'm using don't hold a candle to the Audio Metallurgy GA-0's I have with the MastersounD. Hoping that changes when I add in the Discovery Plus 4 IC's to the Frankenstein circuit. Waiting on some XLR-RCA adapters right now.

Wonder why the Franks are only rated at 8 wpc, while some other SET 300B's are capable of 15-20 wpc? Not complaining, just curious.
