Audio Analogue Puccini SE. Remote, 50wpc, EXTREMELY musical, and can be had for ~$1200 NEW.
I compared the non-remote SE version a while back to several integrateds: YBA Integere Alpha DT, Bryston B-60, Aranov LS960i. Although I think the Aranov was actually the best overall in terms of everything hifi, the AA won me over musicaslly.
It has a slight lushness to the mid's that is very smooth and appealing. Yes, a coloration, but OH so musical IMO. Not quite as lush as old tube sound, but a little warmer than neutral (while still not losing detail).
The SE version has two transformers, should provide good power for the Spendors. The regular Puccini may even be OK, but the dynamics, power, and bass are better with the SE.
Whatever you choose, lots of luck!
