What does one purchase after owning horns?

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?

Madhf,
Having owned both the apogee diva & duetta sigs, & had them modified with all the latest ribbons & crossovers I can assure you these will not apply. Great as they can be. The Diva being the least dynamic.

I think what some people posting here are not realising is that powerful amps cannot substitue for the sensitivity and the way the AG horns couple to the air. I dont want to sound like a broken record or an ass, but most of the suggestions as a replacement mentioned so far will not do what the original posters Unos already did. Fact.

The answer to the question is just better horns!

Gotta know the amp unless you are willing to change that as well.

I'm wondering why the bass integration was such a problem though? I've heard some indicate Avantgardes need to be set up correctly to get the drivers time aligned and fully coherent. Were you able to do that?

You'll likely need other high efficiency speakers to just replace the Avantgarde (not the amp) and get what you are used to. I suspect if the amp sounded good on those that it will also sound good on other high efficiency designs.

If you can afford it, speakers using field coil drivers might be able to do some of the same things with a lower power amp. Otherwise, I think you will be challenged to get what the Avantgardes deliver.
