so I borrowed Tims 722 and ran it last night at Big Head Todd...no real comments on sound yet as I have not had a chance to do more than a cursory listen, but one thing I thought was interesting, I had his 722, in the portabrace bag made for it, in my mountainsmith bag on the floor next to the stand, and between the bass thumping and the people dancing, the floor was definitely bouncing. I was a little concerned with the 722 being a HD that the vibration may affect it. Having not listened to it, only watching it, it didnt seem to hiccup at all. Will report more when I listen...
Also, the portrabrace bag is sweet, expensive, but basically it suspends the unit in the bag, and fits the huge battery. Due to the fact that it suspended the whole unit up, I was able to run it vertically, since the back of the unit was even, vs. when the big ass battery is the back...
