Surprised nobody has suggested the Modwright LS100. I have owned and run McIntosh C2300, C500T and the Aesthetix Calypso Sig and I prefer the LS100. I run NOS Melz 1578(6SN7) tubes and NOS Mullard GZ37 Fat Bottle and the sound is magical. Currently paired with Odyssey Monoblocks and couldn't be happier. New pricing still under your budget and used way under your budget with plenty left over for tube rolling:)
