I have not replaced the panels though I have washed them. I have pretty much replaced everything else in my system since I purchased the SL3s. So I am wondering if I should consider upgrading my speakers also. I agree that the SL3s are one of Martin Logan's best and I am not unhappy with sound. But I would like to see how they compare to some current offerings.
Larryken, Have you heard the VR-4SR MK3 and if so how do you think they compare to the DB-99? I can find very little on the DB-99s other that one review. One the other hand the VR-4SR MK3s are current and maybe I can find a local dealer for an audition. I have read a couple of reviews on the VR-4SR and they sound interesting.
