New Coincident Frankenstein 300B Stereo Version


Coincident has a new stereo version of the Frankenstein. I currently use Coincident Super Victory IIIs speakers driven by Pass Labs XA30.8. My preamp is EAR Yoshino 868PL.

Logic tells me the Frankenstein Stereo would be a steller match with my speakers. I have never had SET amps in my setup before.

Just wondering if I will be going the SET route, would I lose bass?

Love the Pass XA30.8 but curious about what people call "SET magic".

Any thoughts would be appreciated.

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.

Where are you with respect to room size, listening levels and music genres?

Do you alternate your Frankenstein and Atma-Sphere M-60s on your Von Schweikert speakers?

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.

I own Coincident SVII speakers and still own the Frankenstein monos.  However, I found that the Franks just didn't really have the guts to do justice to the SV's.  My room is about 14' x 20' x 8' and I do listen to a fair amount of orchestral music.  In contrast to the experience of others above, I found the Atma-sphere M-60's to be a much better match for this speaker than the Frankensteins in my room with my music.   My M-60's have the V-Cap upgrade, the M-1 power supply, and have enjoyed the benefit of careful 6SN7 tube selection.  Also relevant is my use of the Coincident CSL with Psvane WE replica 101Ds.  The later coupled with the Atma-sphere amp provides a very nice measure of SET magic in my system without the downside associated with driving low efficiency (yes, 92 dB for an SET amp is low efficiency) speakers. 

As I said, I still own the Franks and on very rare occasions rotate them into the system for a day or two, but they don't stay longer than that.  If I were using speakers having an efficiency in the mid to high 90's, it might be a tougher choice.  The Franks really are wonderful amps when equipped with top notch tubes.

I have no experience with Pass amps and won't speculate on how they might compare with the Franks in your set up.  But I will say that if you are buying a new amp for your speakers, I just don't think that the Franks will be the best choice.  

I have found my SVII's to be wonderful speakers, but their performance is perhaps more system dependent than some other speakers.   The SVIII's appear to be a very similar design using better or newer crossover and drivers.
