So, I recently saw a review of the Rogue Audio RP-1 tube preamp. It is being touted as a great entry point to true high end sound. At <$1,800 it seems like a great deal.
My question is: How would one of Frank's tubed preamps in the same price range compare to the RP-1? Not likely anyone has directly compared them, but thought I'd toss this out there.
Thanks for any insight!
