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.



As you know, you will get a significantly different sonic presentation with the amp you are considering over the amp you are now using. My experience with SET was mixed, BUT the mid range was glorious. Tones sounded lifelike and spatial qualities  were most satisfying. I don’t think you will lose bass but you should get a much different sound. I am not familiar with the amp you are considering and perhaps an audiophile near you might be able to let you listen to his 300B rig.

@sim_audio_nerd - suggest private messaging member charles1dad , though he may see this thread and respond directly. He has coincident speakers, preamp  and Frankenstein; and I find him to be objective in providing his thoughts

I have Coincident Statement II pre and 845 Turbo, both are not of golden tube sound, more about accuracy, transparency. I also have custom built 300B monoblocks, none have bass bloat or high freq. rolloff. I'd expect the Coincident 300B would be voiced similarly as my 300B and Coincident equipment. I'd expect more harmonic development with the SET vs Pass.


Yes, Charles1dad would be able to more accurately describe Coincident 300B. Also important to use one of the upper crust 300B tubes with any 300B amp.


In regard to a successful pairing of the Frankenstein and your Super Victory III (SV III) it depends on your goal/objective/listening habits.

I have used the Coincident Franks MK II mono blocks, Statement Line stage and their Total Eclipse II (TE II) n combination for 13 extremely happy years. This set up has exceeded my lofty expectations when acquired.

A key factor is although the SV III is relatively an easy load and moderately high sensitivity (92 db and 8-10 ohm load), my TE II (94 db and 14 ohm load) are even more so. Thus an even better match with lower power SET in general.

How large is your listening space, how loud do you typically listen and what genres of music to you listen to most often? These factors will determine the degree of success you may experience. If your preference is large scale classical music at higher volume you may want more than the 8 watt SET provides.

For my listening needs (Vast majority acoustic jazz combos, smaller scale classical  and some blues) the Franks are remarkably good, actually sublime. They are actually very good with large scale classical  at very reasonable listening levels. But if this were my main fare of music I’d have a higher power SET (845, 805,211,GM 70 etc.) or higher power OTL amplifier.

So it really just depends on what you are seeking to achieve. My previous amplifier was a very good push pull 100 watt (UL mode) 60 watt (Triode mode). This amp has more ultimate high volume potential (If that matters, non factor for me) more bass weight and punch (Franks are actually very good here but 8 watts is not 100 watts). Bass texture, tactility and nuance with acoustic bass/piano is better with the Franks.

In all other sonic parameters I find the Franks superior. More emotion conveyed, inner/micro detail and nuance, tone, timbre and overtones/harmonics a level above. Just a more engaged and compelling listening experience . Unmatched midrange truthfulness of instruments and human vocals in my opinion.
