I'm aware that bypassing the fuse could be asking for trouble and I'm willing to take that risk. In the last 30+ yrs of being an audiophile, I've blown only a couple fuses and those were in Chinese made tubed equipment (not a knock against Chi-Fi). Everything is plugged into a balanced powered conditioned which has a circuit breaker built in so probably not too much of a fire hazard. I don't leave the equipment on all the time nor unattended. I'm just wondering if using such a poor conductor as titanium could be a problem in itself. That's the question please.
Question about suitable fuse metals
I've been wanting to experiment with audiophile fuses for a while but the cost and the concern of blowing one of these costly fuses has kept me from purchasing. However, I read that solid slugs actually sound better than fuses and cost WAY less, so I purchased a 6" rod of 99.99 copper and, because I wasn't really thinking, also purchased another 6" rod of titanium. I guess I was thinking of rhodium, palladium, or platinum, not titanium. I had these cut down to 20mm and, so far have tried them in my amp, a Red Dragon S500, and my DAC, the Bel Canto 2.8, which I run direct without a preamp. The titanium slug sounds pretty darn good in the DAC, noticeably better than the copper. I tried one in the amp as well and that combo did not work well at all. The amp is doing better with the copper slug. I looked up the electrical conductivity of titanium and found it is a rather poor conductor. Is there any risk to the DAC using the titanium slug, given the poor electrial conductivity? Thanks for any relevant input.

Use a non-contact digital infrared laser thermometer gun to check the temperature of the titanium slug while playing music for at least an hour. Put the case cover back on and continue playing music for an hour, then check the temperature again to make sure the reading is not higher than the previous reading. By the way, test your system with this video to see how your system performs, it will also tell you how good your hearing is.😉 |
What fuse holder are you using that lets you substitute a 6" solid slug? At this point the only thing it sounds like you are doing is tweaking the voltage across the DAC. You’d be safer / better off with a variable voltage supply, but seriously we are deep in the flat earth / Mad Mike Hughes territory of experimentation. Get yourself a safer hobby, like making headphone cables.
