sponge bob,
There is a comparison between the YSM1s and the Tannoy SBMs in the July 1996 issue of Electronic Musician (which is conveniently posted ont the Yorkville website).
I don't know how the SBMs compare to the Reveals. And the YSM1s are the only near-fields I've ever heard. I wish I could help you more.
Since my last post, I haven't had a chance to listen critically to the YSM1s. I did listen to one cut - "Count On Me", by Lucky Peterson - just because it has an extremely low, burpy-sounding bass track and I wanted to really enjoy the YSM1's bass response. Having never heard any other near-fields I have nothing to compare to, but I am completely astonished at the YSM1s full, flat, extremely deep and solid bass.
Can anyone recommend some cuts to test the highs and mids?
