The film caps add a bit of clarity up top, the electrolytics are a little grainy in comparison but not something that less discerning ears (like mine) notice until the film caps are in. They also seemed to tighten up the bass a bit. There is probably a lot of audiophile jargon that can be used to describe the differences but most of it is not in my vocabulary. Suffice it to say that I find films to be an improvement. Fairly subtle but you dont have to strain to hear it. Most agree that the biggest single improvement is Speedball. Lots of caps to choose, many fit inside the chassis ... Solen, Axon, Mundorf MKP, Erse juts to name a few of the more affordable ones ... all should fit, atleast the lower voltage versions. Im sure there are others as well.
