I would also opt for SS. I had the Linbrook Sig floorstanders (before upgrading to the D1) and tried tubes on them: unless the tubes had a lot of juice (75 watts+), the sound was pretty flat. Not sure about your speakers, but mine had impedance that dropped pretty low. You may be unlikely to get that sort of power at the price you are considering. The Decade line does much better with tubes, due to the steady 8ohm impedance, FWIW. I ended up setting with moderately powerful SS amp with my Linbrooks (McCormack DNA-125 revision Gold) and also tried amps with more juice (a very high-end Karan integrated, the Simaudio I-7, Herron monoblocks, bigger ARC hybrid amp) and found that the juice that the McCormack provided to be plenty at normal listening levels; the higher current of the others wasn't really noticeable. All of these amps sounded really good on my speakers; I probably liked the Karan and the McCormack the best (at least once the McCormack was mated to an ALD-1 preamp with platinum upgrade).
From my experience, I would go with a moderately powerful SS amp, and perhaps a tube preamp, would be a good combo. I ended up with both a SS amp and preamp, and the pre sounds more "full" and tubey than most of the tube preamp I tried. YMMV.
