Vandersteen Treo vs 3A Sig as upgrade

"What is the character of the speakers?"

The simple answer is, I the speakers are neutral. Not hot or rolled off. What you can do with this information, I have no idea. I heard the Trios in a different room, with different electronics and different music than you. You also need to consider my personal taste in equipment, my level of listening experience and my definitions of subjective qualities. If you take all of those things into consideration, you should be OK.

((What is the character of the speakers?))

Neutral honest messenger, with proper set up.
((Are the speakers hot on top?))
Not at all.
((Are they somewhat loose on the bottom?))
No,

((( OK so far no responses from any owners or any pertinent info on the character of speakers themselves from any knowledgeable source )))
Could it be that most Treo owners are too busy, probably listening the the Grateful Dead or Schumann.

This is why you want Carbon's properly set up with No Feedback amps. Take a look at Bernstein's face loving the moment. Talk about a well oiled machine.

Nice quip from a Vandersteen dealer.

I too hope an owner or two will chime in with some honest, unbiased info on what it's like living with the Treo. Especially someone who has upgraded from a 3A Sig who could describe the differences in set up, sound and caveats between the two.

Zd452 - Alright, you did not hear what I heard and I will take that into account.

I had Vandy 3A's for a number of years.Then bought new 3A Sigs which I've had for five years now.I've heard the Treos twice at two different dealers, set up properly at both with reference level electronics at both.My opinion mirrors yours.I definately felt the Treos were hotter / brighter on top. Bass not in the same ball park as the 3A's.Don't seem to have that signature Vandersteen family sound.Cost alot more money than the 3's but in my opinion,aren't a better speaker at all.I'd like to see Vandersteen incorporate a good ribbon tweeter into their designs and drop the metel dome. I'd like to also see a 3A Signature Wood version. Maybe some day.

I compared both speakers in my room using an Aesthetix Atlas, ARC REF 3 and a Grace M905 DAC using a Macmini running Pure Music. I am assuming you listened to the non CT version of the Treo in my comments. (I did find the CT version a little bright in later listening to that speaker in a dealership compared to the non CT version after both were set up properly.)
I did not find the Treo any brighter than the 3a Sig overall. The Treo has a little lighter balance which accounts for it sounding a little more open. The 3A Sig definitely has a better bottom and a bigger sound. I didn't come to the same conclusion about the Treo midrange. I thought the 3A Sig sounded every bit as smooth and refined, just not quite as open.
The 3a Sig has undergone some changes in the last year or so with the addition of the same midrange as the Treo (woven mid) and uses the same tweeter. The bass was tightened up also. The newer 3a Sigs do not sound the same as the previous model.
I ultimately bought the 3A Sig for it's better bass and bigger sound. I can live without the some what better attributes of the Treo being slightly more open.
Lastly, it has been my experience that dealers do not set the speakers up properly for demo. If they don't measure your ear height and sitting distance, there is NO way they are set up correctly. Vandersteen's certainly are not a sit and listen speaker!
