Actually, nothing's wrong with mine. I guess this all started with another thread about speaker placement for my VR-4 Gen.III's and my questions on overcoming possible issues with my listening room. I felt that two doorways to the front corners of the room behind my VR-4's could be causing less bass than I'd expect from them. The next thing you know after exchanging e-mails with VSA and then with Albert himself, he mentioned room correction, speaker placement, speaker cables and ultimately, the upgrade to the SR Mk3 version.
Since we're "on the subject". why did you do the upgrade on yours and how much of a difference did it make compared to your "original" VR-4's? Was it a "why didn't I do this sooner" kind of change?
Thanks!
