kinda i've read some reviews on here and DIYmobile .. it does improves the SQ however its automatic EQ system isn't every one's taste.
One of the quote i remember from the reviewer is : " The Imprint changes the regular bass note to a low drum notes, highs is more clarity and definded very detail". HOwever he said at the end it lacks the ability to manually adjust the EQ to his taste.
So... if u know a shop that let u ret the processor, borrow it for couple of days , wait til everyone goes to sleep then do the tuning to get best results.
