New MOFI speaker (Andrew Jones)

Which (less than $3,500) amps do people recommend running with their SourcePoint 10s? I recently acquired a pair and am driving them with an old Rotel RA-970BX. The sound is great so far, but the bass could be tighter and mids a touch more pronounced. It also seems like my right channel is slightly quieter, even after adjusting the DC bias, so the clock is ticking on this amp. From what I've read/watched so far, people seem to be using:

• "Warmer" Class D amps like the Rose RA 180 (Andrew Jones @ audio shows), Rose RS 520 (per a local dealer), and, @everest_audio's rec above, the Bel Canto C6i.
• Other warm sounding SS amps like pass labs and occasionally tubes

More neutral amps may not be the best match given the chance of too much treble extension (Luxman 595 ASE + PS10 = too much of a good thing). What do people think will mesh well for a slightly warmer sound?

One route i've been considering is a tube pre (Rogue RH-5) and then a more basic Class AB amp like an Odyssey Khartago or Van Alstine SET 120. 

I really enjoyed the SP 10’s sound, but the size was a bit too much for my living space to where i had to unload them. I would be willing to revisit them at the smaller size in exchange for less bass depth and slam.

• SP 10: 14.5” x 22.5” x 16.6” (WxHxD), 46.2 lbs each

• SP 8: 11.4” x 18” x 13.2” (WxHxD), 27.9 lbs each

Audiophile Junkie just posted an interview with Andrew Jones on the SP 8: https://youtu.be/b-OI6FwRAiE

It's the exact same driver as in the SP 10 but trimmed to size.
