Hello. I auditioned both the 140's and 220 Mk II's in my home a couple years back. Sonics are very similar. The 220 Mk II's sounded a little fuller in my room but the room I had then was far from ideal, The 140's image really well and are easy to place in the room. I think if you get some really solid 24" stands, you will do very well with the 140's.
But since you mentioned other speakers to consider, I would look at the Silverline offerings. You should be able to pick a used SR17 cheaper than the 140, and it's easier to drive and IMO, a much more "musical" loudspeaker. Don't get me wrong - Dynaudio is great co. and makes great products, but I think Silverline has better execution, in terms of value and every day listening. Silverline finishes are drop dead gorgeous as well. I had a pair of SR12's and they were allot of fun to listen to - very musical, articulate, and excellent tone and tube friendly if you ever decide to go there, do to the linear 8 ohm impedance and higher sensitivity (between 87-90), where as Dynaudio is also linear but at 4ohm, 85-86 sens. Blessings to you and have fun!
