Help me choose an amp

My Aragon 8008 died. Now I must replace (OK with me,
I was burned out on the "solid state" vibe anyway).
Want to find a warm, musical, non-fatiguing power amp
(not integrated) for a large bedroom (26 x 24 x 8).

Must integrate well with:

McCormack SST-1 drive
Meridian 563 DA conv.
Audio Research L7S pre
Thiel CS2 2 spkrs

Listen to rock, pop, acoustic music, some jazz. Prefer used tube or warm SS-type like Bryston. Prefer to
keep the price tag under $1200. Ideas?
