"My room is 13 feet wide-is that wide enough for a studio 2 or 1? 30 ft length, open to hallway and 8 foot ceiling. also considering sophia 2 or watt pupp 7"
Plenty wide for all three speakers you mention, as well as Revel Salon 1s or 2s.
"If you want a little body I would stay way from dry sounding amps like Krell and Bryston."
Good rec. The very revealing beryllium tweeters in the Salon and Studio 2s don't need any further reinforcement from your electronics, but the woofer area is large and begs for amplification that goes deep with authority.
