I have a Music Hall 7.1 and it's probably the best turntable I have. I've seen and heard the Ultradeck and if I were in the market for a new table, would give it strong consideration.
Rather than worry about the wall wart, what you should be much more concerned with how well the turntable is isolated from sources of feedback and the quality of the bearing, tonearm, and connections.
The Music Hall can play louder and with more clarity than any of my other tables without suffering from feedback or other issues due to its design. The decoupled motor, the design of the plinth and feet all contribute to that.
As far as the power supply goes, the Project Speed Box or Music Hall Cruise Control are upgrades worth considering. I have the Speed Box which is supposed to improve speed stability and makes it possible to change speeds with the push of a button, instead of adjusting the position of the belt on the pulley.
