Welcome to the forum.

1) - Don't know, but someone else surely will.

2) From what I've read in the past, the differences are very minor with the exception of the sub. The difference between the old EP-350 and the current is significant. The newest 350 has gotten rave reviews as a real step forward from the prior version. I'm not saying the old 350 is bad... just that there is a noticeable difference there between old/current.
