Were to get fuse box for dedicated line?

Bob, as usual, you are a great source of info. As an aside, if someone is having trouble locating ceramics (I haven't really been able to track any down up here in Canada), I'd suggest using the plastic, re-settable "mini-breaker" type fuses. I am using these (15 amp versions) and found them to be very slightly smoother than the standard plastics. I was actually expecting the opposite when I compared them, suspecting that the ability to re-set the fuse would compromise its ability compared to a standard version, but that was not the case. A 15 amp re-settable will, however, sustain short bursts of up to 17-18 amps, and, I am only guessing, but think that this may contribute to the slightly better sound quality.

I'd like to rescind my post above. This thread put me back into experimentation mode this morning and I removed the "mini-breaker" type fuse and replaced it with a standard plastic. They do sound quite different. But I've come to the conclusion this morning that the "mini-breaker" was rolling off the highs as well as being inaccurate in that area, leading to a perception of being smoother. But the standard fuse is definitely more accurate and extended (possibly not a great thing with bad digital recordings). My tv is on a separate circuit and I was running a mini-breaker on that as well, which I replaced with a standard plastic, which in turn confirmed my findings on the audio side by offering up a slightly better picture.
