I own 33s and 3100s, and feed both pairs with MS200s. I really can't say that I 've listened critically to the two side-by-side. I'll give it a go (one short flight of stairs) and report back. What sort of music do you prefer?

However the differential between used prices for 33s and 3100s now seems to be a lot closer than when VK was looking, possibly no more than �100 if you look in the right place. Frankly I'd pay the difference just for the additional ease of setting the DSP3100s up, although the 33s are a little more subtle without the glass display.

I'm going to PM you with a suggestion, since it involves "They Who Must Not Be Named"...
