I listen to all of them ,depending on the CD source material poor recordings don't sound good on the infinity they show all shortcoming of a recording but the IRS Beta are incredible with great recordings. The Klipsch set up is nice but limited in performance but still a nice blend of musicality and detail. the Legacy speakers are the Illusion similar to the Whispers driven by a Jadis DA50, they have a nice mid-range.The low end I am not that happy with but I believe can be better. I need to put some work into the amplification set up with Bi amps.
The base of the infinity is near impossible to beat (had to move the them further from the wall). The Klipsch-horn have my hart for the 400Hz range.
