Simaudio LP 5.3 Mods

I have, within the last two weeks, recieved my LP 5.3 back from a Signature upgrade. I just want to relay to owners of these units how much better they can be made to sound with some TLC. The stock units are very good, but one that's had the "treatment", will absolutely blow away those without. What I hear from my unit is on a par with anything, regardless of price, that I have heard to date.
I won't make any recommendations as to where to have the work done, but be advised, with an extra $400, you can have something special, and exceptional.

Just FYI
Regards,
Dan
