Let me add my 2c.
I used to have the 2CE Sig, then powered by a 50w tube amp with lots of current. It sounded greated, but I couldn't get ride of an irritating ringing from the tweeter. My understanding was that the 3A Sig tweeter was supposed to be an improvement over the 2s. Anyway, I later sold them off and purchased the Cabasse Baltic/Thor combo which I am very happy with till now.
Many moons later while at a dealer/friend's shop, I again heard the 2CE Sig II(new model) which supposedly has the upgraded tweeter from the 3A Sig and it sounded surprising smooth and good, no irritating sounds from the well-behaved tweeter at whatever frequency it was. Further investigation reveiled that it was the amp powering the 2CE SigII which had such good control over the speaker even when pushed loud.
I therefore advise that you consider the Sanders ESL amp for your 3As.
Another point to consider is power supply. Some have raised it already, but I'm not sure if it was fully considered, especially with CD playback. Till now I have always used the PS Audio P300 in "sine" mode to power all my source equipment. While the multiwave has always been recommended by the manufacturer, I've found, after extensive listening, that while it does enhance detail, it does this to the detriment of the music's flow. The pure sine wave let the music flow more naturally and smoothly.
If a lot of users claim the 3As are laid back, its hard to image that it is at fault unless you have a lemon. So chances are the fault lies somewhere else - ie the power amp or the power supply.
Of course these are just my "guesses" based on my pass experience with Vandy speakers, but I think you should not give up on them so easily. Going to an all warm setup may not be the best solution as it will tend to mask detail. As a musician, I think musical coherence in terms of tonal accuracy and musical timing are paramount to your enjoyment of the music.
