Just chiming in on this thread and am happy to add my experience. Based on a comment in my system description I sent Michael two of my old dual lead MPCs to mid to Ver.2. They are on my two PowerCells and surplus as I'd already changed them out to Galileo MPCs.
Having gotten them back (super fast by the way!) I am very pleased to say that they represent a nice upgrade even on the Galileo. My system is finely tuned so changes such as the addition or removal of one HFT are pretty apparent. In this context the MPC Ver.2 go a good step towards making the system even more natural and open --
sounds are more natural and integrated and it is easier to her each instrument in its own acoustic (case in point “All I Want” track 2 on Tierney Sutton “After Blue”, untangling the bass from the vocal is what this track is all about, ideally the bass should be well separated in space from Tierney's vocal, and the vocal itself should have uniform echo into each corner of the room (a really hard trick to pull off if your room treatment is not ideal)) -- the MPC upgrades made a good improvement in this regard
I'll now be sending six more Galileo MPCs to Michael for his work and will report on the cumulative effect
