LSA 1's are in the home theatre. It is FANTASTIC. I suppose it's the voicing, plus the fact that they are not quite as revealing as the LSA Statements or Silverline 17.5, but they are a match made in heaven with my Marantz AV receiver. Not as detailed as my Cary Silverline rig but very beautiful at reproducing music. I'm using LSA standard center, which is of course an excellent match (their better center speaker I think). However the center speaker is very large, so it's a bit awkward and took me time to find a suitable piece of furniture to hold my AV system including the center.
BTW I recently started using the new $99 Apple TV to stream audio from iTunes on my Mac to the HT and use the built-in Marantz DAC. Again, it sounds very lovely, likely due to the slight forgiving quality of the LSA Standard (either that or just the speaker voicing.).
