Coincident Statement linestage is perfect match for the Frankenstein's, certainly not tubey sounding, far more about transparency, resolution. But then it delivers on the things tubes, especially DHT does best, harmonic development, immediacy, micro dynamics, all the things that make it seem as if performers in room.
I have modified MkII version, I can only think of one pre I'd consider as contender or replacement, the Vinnie Rossi L2 Signature DHT.
The Coincident line seems so under appreciated IMO what with it's direct sales model. This pre would sell for far more with different business model, the power supply of Statement is simply massive for a pre and the build quality is beyond reproach.
