what is the best super speaker and why?

The Soundlab's are a great value, in my opinion they have many of the best capabilities of the group mentioned above, all of which are excellent speakers, and which you would likely be happy owning. They are relatively easy to get good sound out of without taking over your listening area. However in a recent spate of listening done over a two day period to Soundlab’s and the Avantgarde's, the Avantgarde's carried the day clearly, by a significant margin; with a knowledgeable dealer doing the setup, they are amazing..otherwise they can sound pretty mediocre. I have been an Audiophile for 25 years, to date the Avantgarde's are the best I have heard; I am currently saving to buy a pair. Avantgarde Trio's are in the 30k range, and are their best performing model; however the Avantgarde Uno's are amazing for a third of the price, and in my opinion best in many regards, most of the systems you have mentioned...but again, only with expert setup will this be true.

Albert, you’re assuming it was the same dealer..I never said it was.
Ne Plus Ultra for the Avantgarde's and Sound Mind Audio for the Sound Lab's. As I implied, I could easily live with either as both are great systems...but I felt, for my tastes, that the Avantgarde’s clearly had the edge. As for several of the other speakers mentioned, my job as an engineer takes me to other states where I have had an opportunity to hear several but not all of the above mentioned systems as well as the Utopia's at an old friends home...who has deep pockets. So I admit that circumstances under which I heard the systems entailed differing electronics and room acoustics; no situation is ever optimal. My recent renewed interest in the world of high-end audio has been exciting...I kind of feel like a kid in a candy shop. P.S., I am not in any way affiliated with either Avantgarde or Sound Labs...my business interests lie in the medical field.

Albert, your mistaken. Call Brian Kurt, Sound Mind Audio..Austin Texas, there sitting in his home/showroom/ living room, just as big as life; if your interested he is apparently looking to move them at a very reasonable price. Roger West at Sound Lab is the one who put me on to Brian Kurt. As for the quality of the electronics driving them, that is a topic that is open to a whole other discussion that is at best subjective.
I have heard that the Avantgarde's can sound really bad if improperly setup..so I have no doubt as to the validity of your prior experience with them. I have heard them only once at Ne Plus Ultra..also in Austin. I guess I was just lucky enough to hear them properly setup.
To change the topic slightly, several of my recent listening experiences have been in home-based dealerships. I feel that this is by and far a better way to hear a system...as opposed to some of the near anechoic chambers or otherwise drastically altered sonic environments I have heard in several dealerships. In other words. if it can sound good in a living room, with minimal sonic treatments..it can sound good in my house..all other factors being somewhat equal. I have both bought and not bought in the past based upon dealership listening sessions, and have often been disappointed with purchases and likely lost out on good opportunities as well.

It's possible that I was mistaken. I thought Brian Kurt indicated that they were the U-1 design, as he seemed to be describing all other models as being a step down from what I was listening to; if that is the case, I will need to make a point of hearing the U-1. But this just further confirms my point, as I was actually comparing a model U-3 with an Uno; which for my tastes and the circumstances under which I heard them were clearly better...no brightness or hardness at all; and both, I am assuming, around the same price point.
I am curious, as you seem to be well versed on Soundlab's line. The Sound lab website makes no mention of any model U-3; rather U-1, A-1, A-3, M-1, M-2 and M-3. Is the U-3 a discontinued model, like the A-2??? or is it an upgraded
A-2 or M-2?

I would like that, I am frequently in the DFW area on business and often just for pleasure. What would be the best way to contact you to arrange this when I am ready?
