I had a lot of fun using a Prologue 1 Integrated and a Raysonic 128 with the Linbrook Signature Systems (1 Piece). Not SOTA, but pretty good. The Prologue 2 might be better for you as it is a 'faster' amp and might fit rock better. Under 3000 new, lot less used, and it will leave some money left over to play with tube rolling, especially with the PL to get the best match.
New preamp & amp?
I have Tyler Acoustics Linbrook System 2 speakers, an Arcam Alpha 9 CD player, Adcom GFP-750 preamp, Adcom GFA-535 amp and also a Rotel RA-985 integrated amp. I listen to a wide variety of music but mostly to rock. The listening room is roughly 14' x 12 '. I want to move up from the Adcom/Rotel stuff and am looking to spend $2K - $3K. Any suggestions?
