Amplifiers?

Amplifiers! I know Chords Of Orion uses a complex studio rig (Avid Eleven Rack, Focusrite Saffire Pro 40, etc.), and with it, produces superior, studio quality recordings. Downside in my opinion: not cheap, high learning curve, not extremely portable. I'm thinking about a live performance and simpler setup than that. I'd like to just sit down with my guitar, pedal-board, amp(s), looper, and make music. No "post-processing." I know it's a tall order.
So: I have my guitars, pedals, and loopers, but what about amps? What are the characteristics of the amp needed for this music? Clean, I guess, but most guitar amps are all about overdrive and distortion. And I've come to the conclusion that I need to go "stereo". There's just so much need for "depth" in the music, not to mention the ping-pong effects, that a mono amp setup seems limiting. So: Stereo = Price x 2 !
Assuming most of the playing is "living room" levels (not gigging), what are some amps to look at? As I said, I don't see any amps in Chords Of Orion's setup. Andy Othling seems to use Matchless (around $2k a pop!). The Monk doesn't specify amps or whatever. Monochrome Seasons mic's a Suhr amp, (also really pricey!) For mere mortals, can I get a great sound at a more reasonable price, (like under $1k per amp?) Anyone have ideas on this?

Current rig: Guitars: Fender American Deluxe Stratocaster; PRS SE 277 Baritone; Taylor 814ce. Amps: Fishman Loudbox Artist (an acoustic guitar amp), and Blackstar ID:15TVP (bedroom-size modeling amp).
