Hi, the power button is on the front center top plate. Simple mechanical on/off push button switch, flush with the AL billet top plate.
You will in face be able to see and hear the A30's as we will be using two sets of them in biamp configuration with Lou's biggest and newest Flagship speaker (Daedalus Audio).
The speakers are efficient enough to not really need biamping, but we thought it would be impressive to have the bass and mids/tweets biamped for the show.
We will also have the same setup at RMAF 2017 in Denver early Oct.
The new Ambrose One, fully balanced, dual mono tube preamp with external supply will be used in the same systems.
Source duties will be by ModWright Tube Modified Oppo UDP-205 Universal Player/DAC for digital and our Ref. PH 150 phono for analog.
