@ricey I tried 2 HIFI Tuning classic gold fuses in my ARC ph3 phono and ls15 pre. I have noticed a huge change in sound the bass is fuller and deeper with more impact, mids are smother and fuller with great imaging and the highs are smooth and well extended with much better detail. My soundstage is wider and deeper with better placement of instruments. I got mine off of ebay from
Parts_ConneXion_Store
for a great price. Just wish they made a dual element fuse to place in my amp.
