Can a fuse affect sound quality in my Classe Amps

BY ALL MEANS: Find out why the fuses blew. The subject have been discussed/debated a couple times before. There are those that have not tried the high grade fuses, but feel they MUST share their unfounded/untested opinions anyway. Ignore them. THEN: The Cable Company has their Hi-Fi Tuning fuses on sale right now (http://www.thecableco.com/prodListing.php?cat=53). If you don't try them, you are depriving yourself of an audio revelation. Of course: There are variables in system resolution, individual hearing acuity and individual ability/training with regards to critical listening. If you heard a difference with the cheaper fuse, there's no doubt you'll notice a difference in presentation with the Hi-Fi Tuning, Isoclean or Furutech fuses(http://www.vhaudio.com/fuses.html). Whether you like the difference or not is another matter. In my system they improved the over-all organics(more realism) of the sound. I've no connection to the Cable Co. or Hi-Fi Tuning, other than being a happy customer. Happy listening!

Rod, what you say makes sense to me and mirrors my experience. I second every word.

The reason the fuses blew were because I was using a phono preamp to drive the amps directly using the single ended inputs of the Classe Dr-15's, while at the same time having another preamp connected into the xlr inputs of the amps. This last preamp was not even powered on when the fuses blew so I was somewhat surprised.

You can't do that unless there is a switch Lornoah. The amp was trying to drive the other preamp.

There is switch for selecting regular and balanced inputs but Classe still advised that it could cause a ground loop by having two inputs connected at the same time. I decided not to drive my amps directly unless i first disconnect the xlr cables altogether.
