Solid State amp with wide soundstage

Although mentioned above by brand name, I'll be specific: add the Bryston 3B-ST to your list. A fine amp that can bought used for $1000-1200, provided that roughly 140-150 wpc (actual output, not rated output) is sufficient for your needs.

I'll second the McCormack DNA-0.5 or DNA-1. Very open, quiet, transparent, and smooth but with great detail and wide/deep soundstage. In fact, lots of tube lovers have praised McCormack amps. Another plus is you can save your pennies and have them upgraded by Steve McCormack(SMcaudio) into what many call some of the best amps available at any price. I've been using a DNA-0.5 Rev. A for a couple years and haven't come close to even thinking about upgrading. Steve is also great to deal with--very honest and straightforward. Best of luck.

You may be able to find An Aloia amp used for close to a grand. A great amp regardless of price. Sold my Wolcott amps which sold for $9000 and got better sound.
