For instance, if your large couch is leather or something else would alter the sound a whole lot more than imagining things about fuses. If your speakers and gear are all sorted out, try and focus on room acoustic treatments. It is a lengthy process of learning/tweaking (will cater to the tweaking mind) and gains can be significant. For anyone with a technical background, a discussion on audiophile fuses will be just plain obnoxious.Â
