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.



The absolute sound concept has value, but it has limitations. As real world so beautifully pointed out, the absolute sound is not a singular experience in the real world. It is a range of experiences all of which are possible within the same venue.  Some like their coffee unsweetened, some like one spoon of sugar, some like two.

The most important component in any system is the ear-brain, the second is the speaker-room, and everything else follows. 

I suspect that @hilde45 could add much to this discussion if he has time.  

Very pertinent comments from you and @sutts as well. I am in no way suggesting that excellent (which to me means natural bass) performance is not possible with non SET amplification. I was really connecting to what @realworldaudio was explaining as it fit my listenings experiences so closely.

I wanted to make the point that a high quality SET amplifier with appropriate speakers can produce very convincing and natural bass in one's audio system. Bill I do not doubt for a momment you are not enjoying superb bas with your Atma-Sphere M-60s. It's simply the better match for your speakers/room and desires.

In that context same for me with the Frankenstein MK II with my Total Eclipse II. The correct buttons are being pushed.☺. It's all good.


@charles1dad you have never, ever, taken an overly dogmatic position on any of  your posts that I can recall.  I did not misunderstand your comments. I hope no one has misunderstood mine.  

 In actual fact, I agree that SET is quite capable of delivering a very natural and very pleasing bass.  That did not drive me in the OTL direction.  It was the very high THD resulting from trying to reproduce orchestral music with 92.5 dB efficient speakers that prompted the move.  Had I stuck with my 94dB efficient Triumph Extreme II monitors, I would have certainly stuck with the Franks in my main system.

I've grown to love my OTLs as much as my CSL.  But it took a lot of tube rolling to get there, and it also took a lot of work on my room to get where I am now.   I'd go further and emphasize that were it not for my CSL and its SET magic, I would not be nearly as enthusiastic about the OTL as I am.  Going back to my coffee analogy, the OTL/CSL combo is one spoon of sugar.  That is just right for me.

I think Ralph would tell you that his amps are more popular with the vinyl crowd.  I suspect there are not many  of us Digital only OTL guys. 

In the end, there is a reason why my Franks have been sitting idle for nearly 5 years.  I haven't sold them because I still love them, and they are worth more to me than they would likely bring.  I just know that at some point, I'm going to want to go down the Frankenstein road again.  But, it won't be with the Super Victory speakers.  I noticed that Israel has resurrected the Pure Reference as a MK II.  It looks like the Total Victory with PRE drivers.  MTM configuration with side firing dual woofers. Very interesting.  30K.  I hope we will see a review on these.  I think the PRs would work in my room, whereas I think it is probably a bit smallish for PREs.



A friend is a longtime Atma-Sphere owner and I am  familiar with his MA-1 mono blocks. So I feel that I can extrapolate the sound of your M-60 mono blocks. We paired his MP-1 preamplifier with my Frankensteins and result was pure and gorgeous.

I can easily imagine your CSL and M-60 pairing being every bit as accomplished. Ralph has described his OTLs as 3rd order harmonics signature and SET as 2nd order harmonic signature. He is spot on with this distinction. He pointed out that naturally a listener may prefer one over the other’s presentation. Bottom line is either is quite capable of exquisite sound quality with proper set up.

Bill your former Coincident Triumphs were very easy to drive just like my Total Eclipse. In fact I believe that the old Eclipse series of Coincident speakers were probably the most compatible with SET amplifiers. 14 ohm load impedance will do that.😊




Thank you for your kind words, indeed, big part of my audio journey was working on myself, on how I listen to music and what I hear.

Of course, we don't need to learn to enjoy music, anyone with a pair of ears can bask in sound and voice. Yet, there is a massive difference between what an unsuspecting victim used exclusively to instant gratification absorbs from the music and how Mozart perceived it. I know, Mozart is a tall yardstick, as tall as it ever gets, but he does set the bar and stands as a warning sign that there's much more to music and music appreciation than just desensitized and sanitized instant gratification and empty shows.

For me getting to learn the nuances of what I hear, getting familiar with the fabric of music made it possible to fine-tune my system to allow further and deeper exploration.

It has been a wonderful journey so far. I'm glad I'm not alone on the road.

 I completely understand this perspective and relate to it 100%.
