Give the caps a few weeks to completely break in. I've heard anywhere from 50 to 200 hours for Solens caps.
I had the XP-55C and thought them the worst sounding properly working speaker system I ever owned, tho' if I found another set today I'd give them another chance.View attachment 738463 View attachment 738462 HI - Just FYI. I have nice pair of XP-55A that I've owned since about 1973. A while back, I replaced the grill cloths with black fabric window screen and I painted the front panels black as well. I've been using them on my man-cave Sony/PC stack for a few years, but am going to try them out on my Onkyo HT one of these days as the primary stereo pair. I'm sure to need to proceed with caution. Pics attached.
