The mini mp is the most acurrate and best sounding pre I have ever run, I would in no way compare it to a mp2, it is much more detailed. I tend to think that the v2s are not very acurrate in the low and low mid area. This is in my mind where the mmp excels, also I fell that the highs are much nicer. Thet ring instead off hiss. If you wnat an all in one box that will run forever off one battery then get a V3, personally I don't like the sound as much, there is a STS9 from the section at Fillmore in denver in the BT section, Todd R has my galactic from the same venue, and may be posting it soon on co tapers.
