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 know that @sns is using the Lanlai Elite 101D in his CSL and has had no problems to my knowledge. So I suspect that the current production available via Grant Fidelity are of good quality. I may at some point give them a try but for now I’m very happy with the Psvane W.E. Replica 101D, very happy.

Bill, I also believe that the 101D is a brilliant preamplifier tube but for what ever reason is not even close in popularity compared to for example the 6SN7. I’m very familiar with the 6SN7 and it is no doubt a very fine tube. Of course implementation is a major factor in determining ultimate sound quality. What impresses me about the 101D is its sheer purity and transparency. It seems to have nearly zero editorializing qualities, yet is by no means sterile/lean/analytical, just pure.

If the rest of the audio system is capable then one will hear natural and beautiful tone, timbres, overtones/harmonics and very fine nuanced musical detail. Perhaps it’s a more difficult tube to work with and get right in an audio circuit. I’m glad Israel Blume decided to give it a go and develop the magnificent CSL.  for us hopelessly devoted music lovers’ 🙂


@charles1dad, the 6SN7 benefits from economy of scale.  More designers use the tube because they are cheap and readily available, and demand for the tube motivates more manufacturers to offer the tube, which in turn drives the price of the tube down.

The 101D never benefited from any of this.  It is tempting to draw a parallel between EL34 and 301B.  301B was always and always will be more expensive to manufacture than the EL34. 

Israel Blume stuck his neck way out when he designed the CSL around the 101D.  It wasn't a great preamp when all you could get was the Shuguang.  Kudos to him for taking the risk. 

It is a funny thing about tubes.  You can go for years, trying this tube and that, and they all have their virtues and weaknesses, then all of a sudden, you find that one tube that is sonically perfect.  For me, the Elrog 300B was that tube.  The old Siemens from the 6922 family fell into that category.  Got everything perfect, and nothing else came close to the Siemens.  The WE101D replica is that tube. No where to go but down.  Purity, transparency, detail, harmonics, tonality, it is all just right.  Oh my, have we drifted from the OP.

Oh my, have we drifted from the OP.

Yes, guilty as charged. You raised intriguing points (As usual for you) I felt compelled to comment on. Sorry. 😊


Duh! I had previously thought of asking Israel about good source for WE101, completely forgot about that route!


Sixmoons had an article some time back in regard to Linlai Elite tubes having early run failures. Grant Fidelity also mentions newer runs having greater reliability.


The Elite solid plate beats WE in some ways, just a bit more presence in mids, WE a little more recessed. Very natural timbre, highs slightly less spotlit than WE, bass comprable. For me, WE and Elite solid plate both equally brilliant, just slightly different flavors.

Great to see happy owners of the Coincident Line Stage (not to derail this thread).

I was actually considering it strongly last year. I totally get the minimalist design but I needed a remote with my preamp. That was the only thing which stopped me. My listening room is upstairs and often I would have to adjust the volume so that I don’t disturb anyone else in the house, specially when I am doing late night listening. I dont want to gettting up many times, specially in the dark. I turn off the lights when I listen in the night.

I agree, Israel does make great products. I am so happy with my SVIIIs. I do get he’s a one man show and cannot let people audition at his place, specially with COVID. BUT. it would have been nice, since I have bought 2 pairs of speakers from him :)

I did audition my first pair of Coincident speaker at his place (Dynamite - now discontinued). Within, months, I upgraded to SVIIIs.

His room and full system is quite something. One of the best system I have heard yet. As you may be aware, he has a double stacked pair of PREs. He bi-amps I believe...Franks on the mids/highs and Dragons on the bass. Killer Kuzma turntable too :)
