Anyone have Coincident Frankenstein amps?

I'm looking for a nice 300B based amp, and this is at the top of my wish list. Anyone have any input on the performance of these amps? Any other brands you would suggest? Just want to try a 300B based amp to switch back and forth with the 845 based amp I have now. Thanks!
I use the Coincident Statement linestage and this combination is truly superb. I generally prefer a top quality active preamp to the passive approach. Opinions will vary on this issue as expected.
Good Luck,
Nguyen get the coinc. preamp and call it a day.
Coincident statement is very desirable, but pricey. That is why I want to know other alternative preamps that are likely to improve the sound of drum beats (over Lightspeed and Dodd), but does not break $5.5K
Nguyen buy it used or call Israel direct, as he sometimes gives deals.
