Considering a change. Avantgarde for Wilson.

Of the two speakers, I prefer the Wilson, no contest.

That's Just one mans opinion, you will undoubtedly receive many comments on this topic.

I second that. I owned the Duos for a couple years and just could never get it right. I've heard the Watt Puppies a few time and they sounded amazing.

You are surely Honda Civic's owner looking at Toyota Tacoma. It's difficult to say, i am driving both of them.

With what are you driving the Avantgardes(tubes or SS), and using what interconnects/cables? They are very revealing of any shortcomings upstream. Not to say there has to be junk before them, but any stridency/glare/grain at all could become intolerable, given their high efficiency and frequency extension. For instance: If tubed- ditch the EH's and find some nice bottom-getter Sylvanias from the 40's. If you were using silver interconnects, a high quality copper might aleviate the problem(ie: Kimber's KS-1121). If your source were a Sony SCD-777ES, you might want to have the piece tweeked(as many others have) as they come from the factory with an upper-mid/low-treble edge. Unless you audition the Wilsons in the same system first: you may buy into the same issue, given that they are also very extended, though not nearly as efficient(93db vs 103db/1w/1m). Either of these excellent systems will act like a magnifying glass toward the rest of the soundstream.

I have a pair of Unos and do not experience any brightness or glare, I would not trade for wilsons as your speakers when set up properly are state of the art and outperform any Wilson.Make sure that your room is properly treated, this is very important, do not use any silver speaker cables or jumpers as they are bright on Avantgardes. I use Mit Bi-wire, low going to the bass, high to the midrange, with a Mit Magnum jumper from midrange to tweeter. Get the best Mit cables you can afford.Use an Set amp, I use an Art Audio Diavolo, and your system should sing.Remember that the problems you are experiencing are system related, not the speakers. When everything is set up right the speakers are unbelievable.
