Concident Frankenstein 300B Stereo

I always wanted to have a 300B SET amp in my system since I borrowed a very expensive one from a friend. I run fairly efficient speakers (Gemme Audio Tanto V2 92db and Klipsch Heresy IV 99db).  But I also didn't want to buy a cheap 300B and have a watered down experience. The issue was now all about price. When I saw that Coincident Speaker Technology just introduced a stereo version of their well reviewed Frankenstein 300B mono's for $2,500 (300B tubes not included) I was very interested - but skeptical given the price which was about a third of the price of the 300B's that I was looking at. I knew that the owner, Israel Blume was well regarded for his amp designs and assumed (hoped) that he wouldn't want to hurt that reputation. I spoke with him a couple of times and then purchased. I am so happy with this amp and believe it's one of the best audio deals in the market. The hard part was getting the actual 300B tubes. I bit the bullet and bought a pair of Western Electric 300B reissues. I really didn't have any other good options because of supply chain issues with the other well regarded brands. No issues at all driving my 92db speakers at only ~40% of my preamp's gain. The whole mid frequency (vocals) was terrific as I had hoped and remembered from my friend's amp.  What did surprise me was the low end frequency -- it's very low and produces all of the textures that you'd expect to hear with those instruments - no muddiness.  I actually disconnected my JL Audio F112 because I didn't need it.   My thanks to Coincident for this amazing (and affordable) 300B.
