@lalitk I forgot - the Mullard’s are marked 12AX7 not any of the variants suggested.
@lewm Brent Jesse has various Amperex/BB available, yes they are expensive but I trust him in terms of authenticity.
I disagree on the value proposition though - while I do agree the Sovtek 12AX7LPS is very good, the NOS Mullard’s and Tele’s are more pleasing to my ears.
@noromance I bought a used Model 4 on Lalit’s recommendation. I think it is ridiculously good for the money. I knew my Goldnote PH-10+PSU-10 ($3k new) was a bottleneck after buying a Clearaudio Innovation and an MSL Signature Platinum, but was holding off a next-level PS for a while. The Model 4 is way better than the GN. Maybe not end-game, but will definitely keep me happy for a while.
The Aric MC is 4.5 times the price of the model 4. Have you heard both?
