If you do go the route of trying out the Atalante 3, be prepared for break in. It'll take a week or two of steady playing. The cone material of the mid woofer is unique in the industry with higher strength than glass fiber or even Kevlar. I used my Ayre test CD (with pink and white noise and frequency sweeps) to aid in break in and it was only after the 3rd time that everything fell into place. It's good practice to occasionally use it anyway.
Don't get me wrong as it sounds great right out of the box but odd at the same time, as if something is amiss. It's just the cone breaking in. I'm now routinely going through 2, 3, and 4 hour listening sessions, reveling in the sound.
Also, if you employ subs, forgo the use of them to see just how low and convincing the base performance is and to judge the speaker on its merits, alone. You'll be pleasantly surprised. I have no desire whatsoever for a sub with these speakers and I've come from using JBL 4319 speakers with 12" woofers.
All the best,
