Vandersteen Treo vs 3A Sig as upgrade

I had my local dealer hook up a pair of Treos to demo them and left with a very mixed impression. I like the overall sound. They have a smoother, more refined and sophisticated midrange that the 3A Sigs can't match. I want that. But the bass was less defined and the top end was bright. The sibilance was very exaggerated - this was with CD. Is this the character of the Treo? Thanks!

I'm currently in Japan for a few weeks but I saw this thread still going so I thought I'd share.
Vandersteen will tell you that set up correctly the Treos with the pair subs will get you very very close to the Quatros and allow you to put the Treos in the proper place,met for your room. Very flexible system. That's from the company. Your dealer can help you set it up and dial it in correctly. It's pretty easy
Here we go found it this morning while reading.

"The Treo works fine with a pair of Vandersteen subs. I used them that way for almost a year until I sold the Treos the first of the month. With all five of the amps I tried it with it needed to be run with one value lower than the input impedance of the amp.

To GreenGrass if you really like the sound profile of the older Vandersteens you really need to listen to the Treo before just plunking down now almost $7000 for them. They to me are much different than the "classic" Vandersteen sound of the 1,2, and 3's. I kept my 2CE Sigs boxed up the whole time I had the Treo and in the end prefered them. I have owned three different Vandersteens over the course of the last 15 years. If you like the "classic" Vandersteen sound you might want to look at the Odyssey Lorelei or the Nola Contender and pocket the significant difference. Or buy a used pair of 2CE or 3A Sigs. There are always ones on either A'gon or USaudiomart. Just my opinion and others may differ."

I thought I post the whole reply.
I guess this just goes to show speakers are like coffee, do you prefer dark or light roast, single origin or blend, store bought or home roasted so many chooses and we haven't even gotten to the point of whether you take something in your coffee.
Speaking of which I need to go get me a cup, it should be done brewing by now.
Interesting thread.I have a 12 year old pair of 3A Sigs. I have done a lot to squeeze out the best possible performance out of them over the years within my means. Recently I thought about selling them and getting the new Maggie 1.7i. I love Maggies and have a pair of 1.6's in another system. I consider that my reference system in many ways. Lately I've been re-thinking my thoughts on selling the Vandy's though. They seem to surprise me every time I change something in just the slightest way, like toe in, repositioning them, tilt back, cable changes, adding a line conditioner, changing seat height, other tweaks for ground control, lowering the noise floor, etc.Today before I stumbled upon this thread I was comparing the two systems with the same tracks, in different rooms of course and they both had a lot to offer. The Maggie's with a Vandy sub just don't have the same kind of bass fullness of the 3A Sigs.However it's all there and articulate! The Vandy's bass is pretty spectacular and also very accurate and detailed when fed the right upstream components and the synergy is there. The Maggies are a special breed and are breathtaking in what they have to offer as well. Two different flavors and both delicious. Barolo and Rioja: take your pick. It felt great to hear them both deliver the goods in all areas. The Maggies just move air in a different manner and when I listen to them I do not "pine" for the bass of the Vandy's. It's there but rolls out in a different way. The Vandy's are remarkable in the way they do bass and detail together. It's all there really with both speakers. Just different delivery.
As far as the 3's vs The Treo's I think they are quite different in the same way and each have their strong suits. I've heard the Treo's many times at John Rutan's Audio Connection and they are SOTA speakers for sure. I would say they are more "fleet" in their delivery, but the newest versions of the 3A Sigs are incredible in their own way to my ears. I have an older version and like I said, they surprise me every time I think I may want to change them. Vandersteen has a wonderful line of loudspeakers to fit all budgets. They can really deliver the goods especially when there is synergy with your components and you set them up properly. I've heard the entire line many times and they are a terrific value. Same can be said about the Magnepans IMHO of course. If you can hear the 3A Sigs and Treos side by side with the same components, that would really be the determining factor as to what you prefer.
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.  

I liked the 3A/Sig much better than the Treo or Quattro.
The caveat is with the 3a it is much easier to set up than the others.
Pretty much plug-and-play.
