There are audiophile grade fuses, Cryo'ed fuses and sand filled fuses. You will hear a lot of differing opinions from others about them. I tried Cryo'ed and didn't hear any difference.
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!
