ShadorneSimple, what sounds best to me. In my case, comparing old to new system is similar to Yugo vs Mercedes.
Well your experience suggests that what you regard as high level components don’t appear to be all that reliable and robust.
It depends on your definition of high level - does it mean high fidelity (in which case a mere fuse should not affect the audio) or does high level mean an expensive boutique custom item that was built and tuned by ear to sound great but without an emphasis on low distortion and elimination of extraneous factors (like a mere fuse) affecting the sound quality.
Why stop at fuses, if one can hear a difference between wires, capacitors, ... then it's flawed. Totally illogical!
