Sorry it took so long to update, but it was a very busy weekend for us on the 17th. Wife was in a BB competition and won her class so we were celebrating!

Anyway I was able to hook the ADA1500 up to my main system. First impression was that although there certainly was more "punch" it was not as much I as anticipated. What I DID notice right away was that the sound was MUCH clearer and tighter than before. I could hear much more detail in the music and it was a much more pleasant sound. It's really hard to put into words. Maybe like pulling cotton out of your ears. I did notice that the drivers on the M80 moved more than before, but not nearly the excursion of the M5HPs, and that's to be expected. I think the next step in upgrade needs to be to replace my 13 year old M80s with current version M100s.

As a side note. When I removed the ADA1500 from the M5HP setup, and replaced it with my Emotiva A300 (150 WPC), I noticed a HUGE difference in sound quality. The M5HPs lost a lot of punch and did not sound nearly as clear or satisfying as when they were hooked up to the ADA1500.

Sound is very hard to describe in words, at least for me. Suffice it to say that the ADA1500 is an amazing piece of equipment and I wish I had the cash to buy more of them to power all of my speakers because it really made a difference in the quality of sound to my ears, and my enjoyment of the music. A big thanks to Ian and Andrew! I love the amp!
