I don't remember the specifics now but my recollection is that they sounded like cheap chinese speakers.
This was a blu-ray DTS demo disc which they play at shows. Pretty entertaining.

I swear I am no subjectivist, how ever I do bow at the alter of Ribbon/Planer speakers. Well some them at least, need to hear some Apogee's again(Graz's Refurb models this time), also Audio Analysis and GT Audio's latest. Also Acoustat.
