New Coincident Frankenstein 300B Stereo Version

Good input by brownsfan. His personal experience is very valuable to the OP’s concerns. Regarding my Atma-Sphere amps, they are an older, non-upgraded version, so it should be no surprise that brownsfan has had a much more positive experience with them than me. I am at a crossroads with the M-60’s as it would cost a few thousand to upgrade it to get sound which might or might not end up being comparable to the Frankensteins in my system with my 99db speakers. Don’t mean to derail the thread, sorry.

I have happily owned the Frankenstein MKII version for 6 years and had a brief experience with them hooked up to Victory II speakers. If I recall correctly, the VII’s were 97db and 10 ohms. I did not perceive any issues with this particular pairing.

Recent Coincident speakers are all around 92-94db and 8 ohms. Some owners of these speakers who also have Frankensteins have ended up bi-amping for better bass performance, or have gone with higher powered amplifiers.

If it is low level listening you prefer, the Frankensteins with very good tubes and cabling will be superb. With loud rock, or large scale symphonic music, then maybe it would not be a good choice.

Between the two, I have a strong preference for the Frankensteins. I use the Franks 99.9% of the time, but it is fun to switch in another amp every once in awhile.
