I finally dug deep and bought a Mesa D800 from a fellow Basschatter. He lived about 5 miles away, so it was an easy deal.
I did not need another head, I already have two, but when did that stop any of us? I will do a more in depth review once I have gigged it, but here are my first thoughts? This was designed by an Engineer, nothing fancy about it. Built in a plain steel box, very black.
Switching it on revealed an always on fan that was very quiet. Setting all the controls to 12 o'clock gives a pleasant sound, but the magic happens when you turn the voicing control. Some really nice tones at house volumes. The Deep control also sounds good, better than similar controls on other amps. I did not turn it up, but I know how loud that ICEPower module can go, and it seems Mesa have squeezed a few more watts from it.
Only time will tell if my money was well spent, but initial impressions are good.
