No digs needed @jrpnde. Glad to have you aboard. It wasn't until just half way through your post that I thought you were leaning towards accepting aftermarket fuses, but there's still time. 😄
Sure, it can have burn in, like a cable and other components that benefit from it and yes, it's purpose is for protection, but like you said, if it sounds better without it, why couldn't a fuse that's made to a higher standard than the cheaply made one sound better? It would most certainly conduct better and vibrate less, which would impart an improvement.
All the best,
