I use reQuests and a Logos across the front in my music/HT setup, with Meridian electronics for the digital front end. I love these speakers!!!! I find them very dynamic, even in my Meridian's "Direct" mode without the subwoofer engaged. The imaging, midrange, vocals and transparency are incredible for music. FWIW, my wife loves how these speakers sound and practically insisted that I buy them over the others we auditioned, even though they wreak havoc on the decor!
On films, the Logos is outstanding because it reproduces voices (midrange) so well, although it's a w-i-d-e speaker and won't fit all setups. I use Linn sides and rears for size reasons, but if I was able, I'd use small MLs (Scripts or Aerius) as side speakers to get the dipole effect.
I recommend MLs, especially if you have a system that will be doing double-duty for music and HT. I don't feel I'm missing out on anything in HT, but a good sub (or two) is essential. They are certainly worth a good listen at a local dealer for both music and HT.
