Does anyone have any hands on experience with this new Mic Pre. I have been very impressed by the RNP and was just about to buy one when I was offered this Summit Audio unit for the same price($475). The two are apples to oranges but both sound very intriguing. The Summit is only a single channel as oppose to the RNP. Also the Summit is a tube mic pre. I am unsure whether that means a true tube based preamp or one of these solid state types with a tube circuit built on top. If anyone has any further insight I would appreciate it.
