Can a fuse affect sound quality in my Classe Amps

I've replaced the 8 amp fast blow fuses in my Classe DR-15 amps after I blew them with the cheapest 8 amp fuses you can buy (they're slightly different than the fuses that were in the amps but the same recommended 8 amps) and I've a suspicion that the sound quality has deterioated slightly? Is this possible or is it all in my head? Can you buy better quality fuses that improve sound? Thanks.

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.

Good plan!! Still- Before you install any expensive fuses: Be certain everything's Kosher, and the amps aren't blowing the cheapies.
