I have the Purple fuse in P15 for almost one week, because the P15 is on all time so it has over 150 hours burn in already. No question, it is the best from SR so far and it beats Orange easily. It sounds different than Beewax Ultimate. The Purple is cleaner with more details yet the sound is as full as Ultimate. I remember Ultimate has better soundstage and a warmer sound in PST. I think the combo of the two may be a very good way to go.
My second Purple should be here in a few days. I will put it in the BHK pre to replace the Orange to see how much more improvement (hard to imagine) Iāll get.
Youāre very welcome David. I think power generator maybe a good place to start since it has the most of current flow, so the fuse should have more effects than other places. Of course I have no proof of that until I get the 2nd one to try.
My regenerator is where I placed my first fuseā¦and indeed the effect
on my system is as if I had gone way uptown upgrading all my gearā¦
that is level of improvement givenā¦
I have an Audio Research amp. It came to me with a wrong spec industrial fuse. I put in a purple of the correct value and Iām happy with the improvement. The amp sounded good but not great. I gave it a better cable and the purple and itās considerably different. All for the best.
Darn!! Purple works. 48 hrs. in purple fuse in my Stellar P3 resulted in several improvements. It will not be going back. I may be replacing SR Blue fuses in other components.
Does the Purple maintain the Orangeās warmth? That was a major difference between the Orange and Blue. I couldnāt`t stand the Blue, which at the time turned me to AMās beeswax.
Do the Purples need to be ordered an amp value up or 25% higher than component specs, as have recent SRās models? SR does not build to industry standards, which starting with either the Black or Blue led to a lot of blown fuses at spec (including one of my Oranges that was above spec).
The Orange was an improvement over the Ultimate Beeswax, but my Premier Ultimate fell apart on first (careful) pull from tight clips, so I decided to steer clear, especially at the price. AMās marketing says it takes many tries get one. Fair warning.
On the Whatās Best Audio fuses thread, some of the Quantum Sciences Audio fuses are touted as much better than the Orange ā and everything else some reviewers have heard. There are several in the line and donāt come cheap. See TweekGeek, and also the review Stereo Times.
In my system purple sounds as warm and fuller than Orange, yet the details and cleanness are stunning (I have one for 10 days and the other one for 3 days and they are still improving).
I do not know if Purple is better in terms of matching amp specification, but I ordered 25% above anyway just in case.
My take is fuses are like cables, some work better in a system than others. I have mostly PSA gears and Purple is my favorite compares to Orange and Ultimate. I have not tried others.
Thanks, thatās helpful. My understanding is that fuses are in effect a special type of mini power cord, completing the run from the power source to a componentās power supply. Thatās why they can have such an effect vs. the cheap OEM type.

Just to clarify a query on the orientation of your internal fuse on the P20.
The end of the fuse that fits into the fuse holder, is that the SR part so that the text would read from left to right?
SR clearly states in their product inserts that the fuses are 1) directional with the direction of current flow being from the āSā to the āRā; and that such fuses need a fair amount of time to break-in. OK. Since I liked the Purple in the P3 regenerator I called McIntosh to find out in which direction the power flowed in my C-33 preamp, so I could get the direction right. The response was unanticipated. The tech was very diplomatic in pointing out that the fuse was in the AC side of the unit and as such the flow of power changed with each of the 60 cycles per second. And what is more, use of such a fuse would void the warranty(expired many years ago) and was not in the camp that fuses make a positive difference.
PS Audio techs confirmed that the fuse is indeed in the AC circuit and that power in both the P3 and the DSJr āflowsā from back-cap side-to front so put the āSā in the cap. I have also heard that after a significant break-in the fuse will appropriately āreorientā itself. This last idea would seem to say that there really is no directionality.
Does anyone, including PS Audio-tech, want to clarify/explain?
We have discussed this in the past without resolution. My hypothesis is there is something about the fuse which acts as a filter and possibly partially rectifies the incoming waveform.
Thatās how the Blue works best in my P15. And when I try it the other way it does sound different, after a year of use. So I am not sure that it āre-orientsā itself over time.
