Happy owner of an EP500, but I've been noticing something lately. Not sure if it's new or if I'm just now noticing, but it seems like the EP500 needs to be turned off and on every few days to perform optimally? I have noted on an SPL meter (all other factors the same) that I can have as much as a 3 db variance after I've played the sub at my reference level for a while. It's not DRAMATIC, but noticable. So for example, when I start listening to reference material it sounds incredible. After a while it seems to drop off when re-listening to EXACT same material at same leve. If I turn the sub off for a while, and turn it back on, BAM, right back to the good stuff. I have verified this w/the SPL as well. My question is, is this a function of the DSP needing to occasionally be re-set?
