@poketacez I would add Cary SLP98 to your list. The combination of the Cary with some Svlvania 6SN7s and Pass XA25 sounds great. I much prefered it to the Rogue RP-5 with the Pass in my system.
Used SLP98s can be easily found for less than 2k
That said, is there anything specific you are looking to improve in your system's sound?
