Right now Emotiva is having a sale. You could get the XPA-2 Gen 2, a 300 wpc 77-lb. power amp, for $799 shipped.
Their USP-1 preamp with phono stage is on sale for a mere $369. Their upscale balanced XSP-1 is on sale for $799.
I sold DQ-10s in 1975 when they first came out, and we found that two BGW amps in bridged mode (making about 500 wpc) really opened them up compared to the 100-150 wpc amps we typically used, so I'd say 300/500 wpc into 8/4 ohms would be a step in the right direction.
