What does one purchase after owning horns?

Grannyring makes good points. Many questions asked of the OP have gone unanswered, still, an interesting thread.

"sold them because of the lack of bass to horn integration." How is that a fault of the Uno's? How did you try to integrate bass, sub/s or horn/s, location, type of EQ'ing? This ain't rocket science especially when you found the Uno's so satisfying to begin with.

Vicdamone,
There is a bit of an issue where the sub meets the mid horn
on the Uno. To be honest since I have had the Trio I find the UNO & the Duo to be weak in that area. It is only due to the sub cut off being so high. Even so both are difficult to beat.

Personally as you could guess I don't know of a better speaker all round than the trio.

As unexplained earlier I had planars for 20 years & from all the revered manufacturers.

Second the Apogee's. Either the Diva's or the Duetta Signatures; the Scintilla although a great speaker is realy hard to drive. Also, the Slant 8, an Apogee hybrid, is excellent and can be bought in the $1200-1500 price range. I have 2 pair to go with my Divas. There's an excellent pair for sale on Agon for $1350 from a guy who is well versed in Apogees.

Responding to vicdamone, I had listened to the Duo and Duo Omega under very good conditions and a short demo of the Uno's in a room I felt was poorly set up. However listening to the Duo and the Duo Omega I was elated with both demo's and purchased the Uno's as a result.
I'm well aware of the inner action of room acoustics, room interactions ect., however after talking to folks in the know and to people who own the same model, I came to the conclusion after a year of trial and error, and with the help of ASC and there tube traps that I would have to spend big money to resolve the issue. I must say there is much good about about the Avantgarde Uno. I loved them for what they could do and cursed them for what they could not.

Perhaps VMPS?
