??? Fuse UpGrade??What Size???

Well I received my Purple fuse yesterday from HiEnd-Electronics..Since someone recommended I not listen for at least 12 hours after installing, I waited until late last night,put the new one in,plugged in my headphones & left it running..A good 8 hour sleep,breakfast & a few chores & 12 hours passed..
 Spent the last 90 minutes listening to Classical music,especially my favorite classical instrument,the cello...Now,perhaps it's just psychoacoustic bias, or a subconscious justification for spending $140.00 on a fuse,but I swear instruments seem to have more physical size & weight to them...Piano soundboards seem almost visceral,as do cello's,with body resonance clearly more defined.. 
Whether or not there is an actual gain in performance of my amp I will never be able to prove but even if it is purely a psychoacoustic benifit I would say I have NO buyers remorse & look forward to seeing if there is further changes as I put more hours on the fuse...

@freediver Littlefuse and Bussman make the best fuses around IME. Just for fun, you might obtain some and then do the same listening test that you did in your post just above.

BTW running an overrated fuse is bad advice. If for any reason your equipment failed with an overrated fuse in it, even if the fuse was known by some to fail earlier than stated on the label, your warranty would be void. If the fuse actually held to its rating, it could start a fire if there was a component failure.

@atmasphere I completely agree with the statement about running an over rated fuse,I stuck with factory spec'd size...
