As a matter of course, I’ve always upgraded from stock fuses. Many here have done the same. I’ve been through a bunch of them…multiple SR colors and Audio Magic M1 and M2 of late. Last week I put in the M2’s in the PMG trio. Yuk. Everything was closed in, lifeless. I usually experience an initial p…

As great as PMG512 is, it does sound a little too revealing in my system. AM M2 fuse brought in a sweeter and warmer sound to my liking. The change made PMG sounds closer to Grimm MU2 in fact:grinning_face: I have a M2 fuse in MU2 also and I don’t think it is helping as much. Your post made me won…

I have a PMG Signature preamp. Do you think the AM M2 fuse would improve it? I feel my system is a bit clinical and almost too revealing like you mentioned also, and I wonder if it will help. The fuse in the factory unit has gold ends, might be a Siba ($5). Are these fuses in most stereo electronics…

I don’t own BMG pre, but M2 fuse has improved every gear of mine. PMG line is so good so the improvement could be less than others. Time to tee off

I don’t own this equipment either, but I have tried about six different fuses in my system and the Audio Magic M1 won out every time and I bet the M2 would be a great choice.

I have used both M1 and M2 fuses and some SR fuses. M2 fuse works great on all my gears. Some fuses did not work well at all such as SR Master fuse that actually sounded worse on Pre and DAC. SR. Purple made BHK pre and Mk2 sounding a bit bright after 6 months. Recently I put a M1 fuse in PMG SACD …

Does the PMG stock fuse have a ceramic cartridge? If so, the stellar and BHK lines have similar fuses. IIRC years ago Paul mentioned that they use a high quality industrial fuse after doing some listening tests. I do not recall the brand he mentioned.

I remember Paul said that too, and I do not think he mentioned a brand name. The fuses I took out from PMGs look exactly the same as the BHKs so they are probably the same. Also, on my long term fuse test (more than one year) the Purple and M1 fuses sounded almost no difference from the PSA stock f…

So I am choosing to interpret that as the stock PS Audio fuses are the second best fuses available! :slight_smile:

Wow, that’s not my experience with the M1 fuses. In my gear they sound definitively better than the stock PS Audio. So many other factors may make a difference. I now only use M1 or any other fuse in my PST and my Decware Dynagrid Jr. in my main system; other components use Swiss Digital Fuse Boxes…

I know. I was confused too. My PST had a M1 fuse for a long time like two years. At beginning it sounded way better than stock fuse inside. But before I sold it I put back the stock fuse, and I was dumbfounded that I did not hear much difference. It could be that I had too much earwax, or some bad w…
