Had a tech in Atlanta re-cap my old Snell E II speaker crossovers. I had modified the speakers with new custom cabinets made from northern birch to the exact dimensions as the original speakers. Also, I recently replaced the drivers with Audio Note drivers. The tech in Atlanta is known as the "crossover guru". He was very reluctant to change anything on a Snell crossover, but I finally convinced him to do it. He actually kept everything the same in the layout. He replaced the caps with higher quality caps and even bundled the caps like the originals to get the same specs. Well I put everything back together, and H..Y S..T!!!! Bass was deeper (makes no sense). There is a very much improved clarity in the mid range. A bit nicer depth, and a more open sound stage. The wife even noticed, so I know it's good. Also, the improvements are not the same on all material. Some cd's are vastly improved, while others is very subtle. LP's so far also fall into the subtle range. The biggest improvement seems to be voices and for some reason trumpets. All in all.......I LOVE IT!
