I was doing a search on Treo's as I have finally put them up for sale (now will have the money to get Quatro's). I reread the whole thread and it is very interesting.
The OP wanted to know what the Treo's sound like. I've now lived with them for well over a year and I LOVE them. If they don't sell, I'll be ok with that. I often have to listen at low levels on Sat and Sun mornings. I am in shock at how great they sound at any level. Even at the low levels they are dynamic as heck. They are like listening to a point source driver only at mostly full range. There was concern over the QUALITY of the bass. Folks, if you want quality, it's there in spades. The quantity isn't what the Quatro is, but again, augmenting with the high pass filter and Vandy Q subs you do get that quantity and the quality will tighten up a spec too. I wouldn't ever use anyone else's sub with it though. That won't work. I listen to a ton of vinyl still as well as high rez, well recorded digital on a very high end DAC. No it's not cheap, but this is about how good the Treo's can sound. The sound was described as a bit behind the speakers. Yes, if you want something in your face go listen to some others. The new B&W's are speakers that are in your lap. Not my cup of tea, but many love that. These speakers must be set up really well (thanks Johnny) because they open up even and give me a very large and realistic soundstage. The stage goes well past the edge of the speakers too. My room is decent. It needs a bit of help on first reflection, but I have MS and am unable to put the quilts I purchased up on the wall where they need to be.
These are chameleon's in that they rock, play large scale orchestral, give me the guitar plucks from Joe Bonamassa's fingers and the emotion of his blues, allow me to love Bill Evan's piano on Kind of Blue and even on Cowboy Junkies, the female vocal can be hauntingly good.
They are just clean. No distortion at all on mine. That allows them to be 'ruthlessly revealing without fatigue' as I posted earlier in this thread. Not only do I stand by that, they have gotten better. I don't think I even had them fully broken in when I originally posted. I also have upgrade a few parts of the system. Not sure if I had the Ayre AX-5 Twenty upgrade at the time. I assume I was using the Empirical Audio OSDE/SE (with every upgrade Steve offers for it).
I thought it was cool that the CT version made the front over of The Absolute Sound last month I think it was. It's a GREAT review and a fun read if you Google it.
