Thanks, that information gave all of us some valuable perspective. Your previous speakers were good ones, and in particular, I have respect for the ProAc 3.8. It is a great speaker. I would think that the Electrons would sound very much like the DI's, and maybe even have an advantage in the midrange, where the driver is more the size that many people think is more ideal for a midrange driver.
I don't have a size restriction partner-wise, but because my room is 13 x 11x 9. Eric says the Electron will be fine with that size.
