Consonance makes some nice-sounding inexpensive integrateds. Pretty good value there. Cheers,
See if you can find a Synthesis integrated amp. There was one for sale here for about $1000. Synthesis is an Italian company and their tube amps are gorgeous and melodious. I have heard the Synthesis Nimis with ProAc monitors and the sound was just amazing. The amp was only 10 watts or so but plenty of power for jazz and vocals in a small room. The other choice for ProAc is Audio Research. ARC and ProAc just sound beautiful together.
