I have a pair of 633 LR Towers, but not the super nice center, its just too big. My system is in my siggy file. I REALLY like the Aperions, and some would call me the "Aperion Fanboy" around here, so be it. And I'm just a customer.
Aperion Audio offers the following redeeming features:
1" Hi Density Fiberboard construction, vs. many companies only use 3/4" Medium Density Fiberboard.
30 day audition with shipping BOTH ways if your not happy.
One year Trade in / Trade up deal. Just keep the packing boxes and you can trade, say the 533 LR's up to 633 LR's with full credit on the 533's. Who else does that?
The Piano Black is to behold, simply awesome. I hear the same thing about the Cherry looking more like furniture than speakers.
And the customer support is awesome. Very friendly.
As far as sound goes, at first I thought they were a little bright on the top end, but I cranked them up to reference level for over an hour, and had zero listening fatigue. I'm a bass nut, so I crossed mine over at 80 hz, and set my big Hsu by ear for a "warm" bottom end. During that hour, my remastered Pink Floyd "Wish You Were Here" sounded insanely good.
I also have played Rock, Heavy Metal, smooth R&B, new country, and 80's country off the Satellite Dish (XM) and they sound great. Only thing I have not played is rap. I'm very very satisfied with my system, and everybody that hears it comments on the sound quality.
Bottom line: Buy any Aperion speaker and try them out. You've nothing to loose.
