I have tried a variety of expensive fuses and would strongly suggest people try the Acme Audio silver plated and cryo treated fuses. Obviously the effect will depend on your system. But they are so reasonably priced it is well worth a try. In my system they were far superior to any of the other fuses I tried. I replaced all 10 fuses in my system with them and couldn't be more pleased. Endless discussions of micro dynamics --- which were improved, or "air" -- which was improved, or bass which was also improved and on and on will not tell you what will happen in your system. Just please try them. Michael is a wonderful guy and makes exceptional products.
