Yeah, That's pretty much the same as I've been able to come up with. There are other XOs designs for the A7s, but none that I can tell are a major improvement over the original. When I got mine from Spkrman57, he pretty much said don't screw with the XO, because you're only going to degrade the sound if it's not dead-on. Could be why original XOs go for a pretty penny on eBay.Before I start messing with the speaker assembly, I need to do some room treatment. This will certainly be more noticeable than XO cap changes. Also, I'm going to start on a SE (811) pretty soon (see Group Build Forum.) My integrated amp (Cayin TA-30) is nice, but I'm hopeing an SE will take me to the next level.......Colin
