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.



Just my opinion, but I think the 101D based CSL  is Israel Blume's finest piece when used with the superb Psvane WE replica 101D tubes.

Has been my assessment for a long time. Simply a stunningly good Line stage and no concerns with regard to power output needs as arises with the superb sibling Frankenstein SET.

Bill, excellent comments in total.  I hope that @sim_audio_nerd reaches out to you.


@charles1dad Thanks for your kind words, my friend.  The CSL can be a superb foundation for anyone not needing a full function preamp.  Stunningly good is the right descriptor.  I'm still toying with getting the latest update.

I actually live in the same city as Israel. I wanted to audition but he told me it's not possible.

He obviously doesn't want to earn your business.  Walk away, there are many other manufactures/dealers would love to earn your business.


The CSL is indeed a special piece, made that much better with MK II upgrades. I also got the Amtrans switch upgrade, much more precision piece than the standard upgrade switch.


I've given up on using Psvane WE101D with no longer having trustworthy distributor/seller here in NA. In last six month purchased two singles,one DOA, another failed at around 50 hours. Perhaps Woo Audio could be enticed to sell 101D, doubtful since none of their headphone amps use that tube. I did purchase my 300B Acme from them, no issues in well over 200 hours now. Chinese stock of Chinese tubes cannot be trusted IMO. Until then, I'm completely satisfied with Linlai  Elite 300B solid plates purchased through Grant Fidelity, wonderful tube. Mesh plate not so much.


I would agree that the tube purchasing “source” is a key factor. I bought my original pair of Psvane W.E. Replica 101D from Grant Fidelity. They lasted a good 7-8 years with fairly heavy usage. I bought my current W.E. Replica pair directly from Israel Blume last year and they have been faultless thus far.

He told me he had several failures with the Linlai 101D and no longer recommends them. Perhaps this was an early run/production issue and current models could be just fine now. Agree with @brownsfan Psvane W.E. Replica 101D is a fabulous sounding tube paired with the CSL. Choose your source carefully.
