I have one just before the most expensive/latest one. SHD I think in my DS.
Brett, Oh, you mean the clover, and not orange-blossom beeswax?
Mine are fed only pure avocado blossoms.
Iâve said it before, none better than the beesâ ear wax versions. Understandably expensive, considering how hard to get the bee to sit still.
Bees waxâŠjust clean out your ears with ear wax cleaning systemâŠmuch cheaper
more effective 
Ha ha 
Just a quick note, this is best left to the professionals like an ENT. Our ears need wax to remain healthy. Itâs the primary protector against infection. Cleaning out too much is a bad thing as is of course jamming it up against the ear drum.
Staying on topic: I replaced all 6 fuses in my BHK 250 with Oranges. The tree had already fruited and the bees had no more pollen work to do so no beeswax. I think the bee union forces a sale on SR fuses twice a year, 3-2 sale.
Ooh, Brett, back before there was orange (or Blue, for that matter) I put the Supreme3 on the rail positions in my BHK 250 and the SR Black for the two other fuses. (two weeks later, of course, the Blue came out)
Did you notice how much improvement you got with the rail fuses? To me it seemed even more beneficial than the mains.
But thatâs just me.
Thanks!

Yes, absolutely but I only had the stock fuses to compare. I ran the stock fuses for a few weeks while the amp settled before replacing all with Orange. After a few weeks I went back to all stock and the difference was quite obvious to me for the better though for the spend itâs a tough call. I would say everything else needs to be well sorted before fuses will show a significant difference overall.
Brett, my 250 had burned in for several years before I replaced the fuses, then did it in stages: rails first with HiFi Tuning supreme3 and second with the SR Black on the two mains. I listened in between and noticed a remarkable improvement with the rail fuses themselves, then a little better with the mains but not as significant as the rail fuses.
I havenât tried the Orange on the mains yet, will save that for when they go on sale.
Wouldnât ya know, Iâd discovered Iâd put in my SR fuses backwards 2 years ago. the Black fuse blew in the BHK preamp after Iâd fiddled with a power cord, so I got a new Blue. The instructions seemed a lot clearer in the new batch, so I checked the direction of the fuses in the BHK 250. Sure enough, Iâd put them in backwards.
So, consider them reversed and breaking in now.
Oops.

I found I preferred them with the S to the back and the R pointing into the unit. I still say you have to try them both ways and determine by the sound.
Yup, the BHK preamp runs the power through the fuse from the back of the chassis towards the front, hence you purring the âSâ at the rear and âRâ at the front is exactly what SR recommends in their instructions. (and is exactly opposite of what Iâve been doing the last 2 years . . ⊠)
But the Hifi Tuning Supreme3 on the rails sure sounded good!!
Why sounded ? Did they blow up ?
I changed to orange fuses on all my products. Do any other PS audio products below have current from from Rear to Front as the BHK Pre?
- DSD Jr
- BHK Pre
- BHK 250
- P15
Thanks!
Getting back to this subject 3 years after last reply.
As a disclaimer, fuses was a no subject for me until some weeks ago.
My original BHK Pre fuse has blown some weeks ago and the local dealer hgave me for free a compatible glass fuse as replacement.
As soon as I arrived home and turned on the system I noticed the sound was different, more resonant on high frequencies, as if all the frequency spectrum went up, less body and less pleasing. After some research I decided to buy a SR Pink fuse to try.
At first listening even without burn in, I was shocked by the impact the fuse had on the sound. Lower noise, higher level for the same volume, holographic soundstage width and depth, very real as if I was in the studio / concert hall. But as trade off, less warm, less body, the bass feels too tight, too crispy highs - with my Planar Magnetic Headphones direct on BHK after an hour I was almost bleeding from my ears - not so fatiguing with the speakers.
After one week (round 160hrs) I donât feel it is settling that much, maybe a little.
Does anyone had the same experience with SR Pink fuse on BHK vs original fuse?
Should I expect with more burn in time (another week) to get back more of the original BHK sound signature, with the positive âsalt & pepperâ from SR Pink Fuse?
I have no experience with SR Pink fuse, but with SR Master fuse I remember even after one month I still heard improvement. So, one week is not enough I believe.
Consider the Swiss Digital Fuse Box with graphene sluggo. It has done amazing things for my P20 and BHK300 monoblocks. I will likely add another (or two?) for my BHK Pre and maybe Directstream DAC (Mk2). It wonât âblowâ - if thereâs a surge, it cuts the current faster than a conventional fuse, and you just reset it. Blowing an expensive fuse is painful to the hip pocket, and puts your gear out of action til replacement. The SDFB + graphene is fantastic for getting the most out of your gear.
I agree that the fuse will take longer than a week to âbe all it can be,â and also that Philip is right: the Swiss Digital Fuse Box is da bomb, it ended my fascination with fusesâI have three with Graphene Sluggos and they transformed the sound of my system.
I have an SR Master Fuse in my BHK pre and I was more like 250 hours for it to settle inâŠ
