I have heard Aeris several times. I really like them- a lot. They have the ability to just let the "music" go and dare any material played to challenge them. They can sound thunderous, delicate, detailed, smooth, throw a huge soundstage, and have unbelievable bass resolution. I could easily live with the Aeris for the rest of my days.
As much as I enjoy Aeris, when I hear Whisper, it's like falling in love again. They have a sonic presence that is just so natural and effortless and right. I believe Bill Duddleston would say they are his favorite if asked. They do have an unusual look though, but after owning a Lampizator BL 7 I've gotten over looks when it comes to natural sound.
I've been a Helix owner in the past (and what a great speaker they were!). But I've been enjoying a loaner pair of Focus SE until the new Legacy V is available. Then I'll have a difficult choice Whisper, Aeris, or the new V.
The V are making thier debut at Rocky Mountain this October.
Can't wait to hear them!
