I am experimenting with fuses on my amp and streamer.

I know there is a fuse inside the aT1 too. Did anyone have hands on experiences with changing these fuses with hifi grade fuses??

Hi TonB, The original 120 Volt Triton One tower uses a 6.3 amp slow blow fuse (measuring 5mm x 20mm). This fuse is located on a small circuit board attached to the backside of the input plate on the back of the tower. Some customers have indicated they've heard an improvement when upgrading the standard fuse to an audiophile fuse. Depending upon the cost of the the audiophile fuse, it might be worth trying. Happy Listening!
