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…

Thanks again Jerryd6, appreciated your standard size fuse info for the PMG DAC 512. Funny, I was ready to jump on the Pink Fuse for the above, basically repeating what I have done for my AI L3B Line Stage Preamp Power Supply and Moon 330A Power Amp with improved results, however, Straigthwire’s ear…

I use the exact same AM M2 fuse in DS MK2 for PMG512, I also like the sound better than the stock fuse in PMG too. I never tried SR Pink fuse.

Good to know DChang05 regarding the AM M2 Fuse in your DS MK2 and PMG512. Speaking with a close friend in the business he distilled the differences for me. The AM M2 Fuse sound was rounder and sweeter, whereas the SR Pink Fuse signature was a bit more airy, neutral, square/focused and simply a bet…

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…
