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.



What speakers are you using and room size?

I have a finished space in my basement  that's roughly  14 x 27 with an  8 foot  ceiling. No problems at all.


@charles1dad your description is spot on.  That is precisely the way I feel about the Frankensteins. My system is in a ground floor room with 10' ceilings.  The room is approximately 16' x 10'.  I use Zu Soul Supremes and I doubt that I am even using 1W.

YEP! And very often well under 1 watt of power. My typical listening levels are C-weighted SPL of 65-75 db with occasional peaks to mid 80s. In reality (Seated 10 feet from my 94 db sensitivity speakers) using small fractions of a single watt. Even with the rare listening at higher levels (Peaks 90-94 db) no sense of strain. However I want to preserve my hearing as best I can.🙂


@charles1dad  Preservation of my hearing was a significant motivating factor for choosing the Frankensteins.  I can listen at much lower levels and hear much, much more detail.

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.
