Taking the dip, but only for <$500.

Thoughts on these?

1) Antique Sound Labs (ASL) Wave 20 monoblocks. I can get a pair for $175 new, w/ warranty.

2) ASL MG SPM25DT (monoblocks) for ~$475 but the tubes have about 1K hours.

3) Baby Sophia for $425 new w/ warranty.

I'm throwing caution to the wind, considering I
(a) No space to put them
(b) Have to find cages to protect my kid's fingers...
(c) Have to figure out a switch configuration or resort to moving cables manually...
