Is there a very nice SS amp around 1K?

Don't forget Forte 4A. Does not meet your 100 wpc spec, but it does pump out 100 wpc @ 4ohm and runs in pure class A. Very sweet sounding, I like it better than McCormack and most think McCormack DNA is better than Odyssey.

BAT VK200 is balanced in only.

B&K might be the answer for even less $$$.

I'm glad you are enjoying the RSA Haley Jim, it does not surprise me that you chose it. It's quite a bargain, IMHO.

As for the amp, I recommended the Odyssey Stratos because of ALL of the criteria you originally listed. SS, around $1K, XLR & RCA inputs, 100 wpc, balanced presentation AND not real old.

I agree with Semi, that my first choice under $1K would be the Forte 4A. Great amp! Can be had for much less than $1K, and will outperform many much more expensive amps. However, it only puts out 50 wpc into 8 ohms, and it IS relatively old. McCormack and BAT are both very good SS amps too, but again, not very new for a kilobuck.

Enter the Odyssey Stratos, this amp competes with many MUCH more expensive amps, and those that tend to 'snub' it do so because it does not cost enough. Search the archives, here and at Audio Asylum. You'll find that this amp will best fit ALL of your original criteria. Should your criteria change, your options may too. However, the Stratos DOES show that there is very good SS for around $1K, IMHO.

Cheers,
John

Blindjim- Here's a little more info on the Hafler 9505:(http://www.barryrudolph.com/newtoys/toys/hafler.html)(http://www.audioreview.com/cat/amplification/amplifiers/hafler/PRD_115814_1583crx.aspx)(http://www.hafler.com/products/hafler_products_details.asp?productID=3276&viewId=3)

You can pick up a very nice second hand Musical Fidelity amp on Agon or ebay in this price range.

I picked up a smooth and refined sounding, reasonably powerful MF A3CR on ebay for about $600. On agon, these come up regularly for just a bit more. I have an affinity for tube-like smoothness in reproduction, but like the simplicity and extra oomph factor SS adds and have been 100% pleased with the MF amp addition.
