After seeing your above post it reminded me I added a couple of silver hifi fuses out of curiosity to a order for some other bits and pieces a while back so I dug one of them out and put it the crack not really expecting much and I am actually quiet surprised and not to sure about what I am hearing having only listened to a couple of tracks so far. For $2 a pop they are not exactly high end designer fuses and are a inexpensive enough way to test the waters.
