I was at the same demo that Gundam91 was reffering to.
the system being used was not tailored to the Magico but rather what the demoing dealer sold.
I believe Alon mentioned the Mini II needed over 100 watts of power and he designs/voices the amps with solid state gear and many amps, but he knows people listen with tubes.
I do agree with Gundam91, the Mini II sounded much better than the V3.
I left the demo impressed, but with the knowledge that a state of the art system which retailed for over 60k, did not trounce or provide significantly more enjoyment than my 'modest' 30k system
