From commercial point not sure if that's true after Logitech took them over.

I talked to Jeanette from UE a good while at last year's LA Meet. When I asked her how the Logitech takeover was, she was very candid in saying that the UE staff wasn't very receptive to it and was nervous about the potential changes that would happen. But in the end, they turned out to be very hands-off with the customs department, and let them do their own thing while offering resources and support.

The consumer stuff that has the Logitech/UE branding seems to just be an afterthought to pay the bills, but their customs operations does seem to be where most of their focus is.

I guess what I'm saying is that the folks who make the consumer stuff are different than folks who make the customs. While the TF10 is part of UE's history, replaced by the UE900 recently, the UE factory in Irvine didn't seem to have much to do with the UE900 (or below), other than probably providing the mothership Logitech, its expertise. In other words, there seems to be a Logitech/UE and a dedicated UE (customs.)

Trying to tweak a TF10 (now discontinued) into having performance more similar to the UERM (in an attempt to make whatever confused statement, i.e. "UERM is a rip off", "TF10 is really a UERM gimped", "UE is ripping us off", etc.) is like trying to add engine and suspension mods to a Toyota MR-S (also discontinued) to make it perform like a Lexus LF-A. And yes, I surmise it's possible with mods to make the MR-S faster or at least very close to the LF-A on more technical tracks such as Buttonwillow or Streets of Willow Springs. But that completely misses the point of Lexus.
