Charles,
The 1 watt is sufficient for my listening needs. A powered subwoofer crossed over at about 60hz handles most of the low end, however the Impacts have low end ability which has surprised me at times.
I replaced all of the stock tubes with Sylvania bad boys 6SN7's and Sylvania triple mica navy issue 12at7's which in my opinion allow the Microzotl2 even more of everything better.
I am not a headbanger, but have cranked it at times to where the volume level is much more than sufficient for my 16x24 foot room. I do prefer nearfield listening while seated 4 to 5 feet in front of the speakers with them 5 feet separated in width. I have spent hours of bliss here.
