For those asking for additional follow up on the X5s here it is. For reference, speakers I have had in my system are B&W, Maggies and Silverline. I have also been listening to my buddies NOLAs (12 inch woofer in box) with OB tweeter and midrange with all tubes driving) excellent and what drove me to look for a new set of speakers. As with Shakey, I have not heard realism and accurate pitch tone like this before. I get a better sense of front to back and side to side placement of musicians, voices as well. Soundstage in my setup does not go very far side to side beyond speakers. I have dialed back the subwoofer a few notches. Bass remains the best I have heard. Dynamics are spectacular. The cannons on Tchaikovsky's 1812 overture are amazing and room shaking if you have the volume turned up. I believe at 160 hrs I can still here improvements, notably in the massive 22 lb subwoofers. I am happy with the X5s in my 22.5 X 15.5 X 9 room as the AMT is closer to ear height, although some have argued that this is not as important with OB speakers. Dynamics are spectacular. The cannons on Tchaikovsky's 1812 overture are amazing and room shaking if you have the volume turned up. Most music I can still listen to at lower volume levels with great enjoyment. However, these speakers are amazing with the volume turned up. If the M3s and M5s are in this same musical ballpark, there are going to be a lot of happy campers out there! Enjoy.
