This is a high-resolution system with emphasis on analog playback and high-quality digital upsampled playback. It is possible to approach superb analog qualities with a DSD system; there is a 2:1 price to performance ratio needed, assuming that the analog equipment is near the top of the ladder.

Listener position determined by near-field optimal acoustics. The goal for holographic sound presentation has been achieved.
I have recently upgraded my phono stage, tonearms and cartridges, preamp, and primary speakers. Now I have the option of surround sound for film, concert video, and sports while maintaining outstanding 2-channel playback at any time. The Lexicon works through the Pass XP-20 unity gain pass through input. Made the wise decision to mount plasma on the wall which greatly increased imaging space.
I just got the Summits in this weekend. You are absolutely right, they are spectacular and a definite cut above the Ascents. Even without woofer break-in, I am hearing things that were "muffled" in the Ascents which I thought were a pretty revealing speaker. The imaging is fantastic. They also look pretty great.
In my opinion get the Summits as soon as possible. I have owned a pair of Summits for six months and they are much better than the Ascent Is. Just one man's opinion...
