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

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

Sweet..I did not know the AG designation related to the physical size..Thanks much..

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...
