Great thanks! That’s how it was meant to be😃

I had them pointing the other way… until I read this and tried it the way Brett suggests. Yes, much better.

I’ve got ~50 hours on all six fuses in my 2 month old BHK 250. The change is quite audible and mostly for the better. The width and depth of soundstage grew as well as an increase in bass in a good way. I do hear on some tracks some rough upper mids but also more extended highs. It’s tough to tell if it’s the fuses needing more time or if that track simply has that rough texture to it and I’m now hearing it more clearly. I don’t do anything different when I make a change like this…I don’t have playlists that I play on repeat, I simply play music like I always have.

I’ll give them 3 continuous weeks to settle then switch back to stock fuses before making my final decision to keep or return.

brett thanks for sharing…my oranges did pretty much the same thing…
they require much “sauteeing”…cook 'em…

Now going from 3rd week into the 4th week here is whats developed…
soundstage so much improved…spatial in space delicate nuances,
initial onset full bloom and ensuing decay (if any present in the recording) stringed instrument attacks and ensuing textures, a musical
sound can now hear is made up of multiple notes…the full breadth
and depth of symphonic music much better rendered scope breadth
depth behind the speakers as well as verticality…

An interesting experience is that now with the orange fuses in all my
gear, P12 regenerator, Emotiva XSP1 Gen 2 pre, Parasound A21…
I find I still prefer sine wave over multi…however…there are albums
that using multiwave at strengths of 2-3 make some beautiful
playback for some albums…before the orange fuses…multiwave
just added weight at the sacrifice of presence and air…now it seems
with the oranges I get more useable flexibility…Amazing who woulda
thought?

My speakers are Focal Aria 948s… but now with the orange fuses
it is as if I had a more refined system and by quite a bit…

So brett keep “sauteeing” your oranges…don’t give up on them…
they will pay off…but in the in between time; they will go back and forth
and at times the mids will even sound muddled up (thick no life)…
Don’t stop just keep a going …the corner will soon be turned…
mine have pretty much turned the corner…

Best wishes friend

Came in late in this discussion but hope this will help others in future SR fuse replacement. This was discussed in replacing SR fuses in the DSD Sr at the time Blue was king now replaced by Orange. Same principle with the Ohm meter for other components. Hope this help.

I will definitely give them their due. I wish they didn’t make so much difference as it makes me wonder how many people have sent back or sold equipment that simply needed better fuses.

Great point, and probably more than we realize…
Years ago Herman VandenDungen founder of Prima Luna got a group
of Goldmund high end engineers and posed a question…“why does high end sound have to be expensive?” or so it went…

So their solution was to buy a bunch of Marantz low end cd players
gut them put their stuff in to these chasis with 2 6922 tubes…thus the AH! Njoe Tjoeb 4000 CD player came into being…
Later they came up with an upsampler thst could be end user installed.

Well so I added the upsampler to my AH! 4000…
Boy oh boy 1000hrs + burn in time…I stuck with it as there were too many positive reviews…and the time came it too turned the corner
but what a long trip that was…yet very well worth it…my AH! 4000 still
hangs around and struts it’s stuff from time to time…

So good things can take time to come around…

Should add a PS A regenerator…that’s the whole enchiladas in
this hobby…

Keep at it brett

The margin on the SR stuff is a bit extreme but hey if the market will bear it…

Didn’t you say you have a P12? I’ve got a P10.

brett yes the margin on SR stuff is a bit extreme but it is a very small niche market and R+D is very expensive but worth it for me…

I went from P5 to P12…I thought it might be a side wise move…

But Paul was so right on the the upgraded tech in the new P12, P15,and P20s

The P12 was a amazing improvement over P5 and both with stock fuses…after my P12 arrived is when I started to dabble with fuses.
So if it is in your budget a P10 to P15 would bring about a similar
change for you…but of course ymmv…

Heading out for awhile catch up with ya’ll a tad later…

Had to correct a couple of booboos

So I received my SR orange fuses on 9-3-20 from
vhaudio.com…great service thanks to Chris VenHaus

My fuses have been burning in or “sauteeing” since then.
Equipment powered most of the time…and using the Chesky
equipment and cable burn in track on repeat.

So finally now the “oranges are cooked” :grinning:…and have
turned the proverbial corner…and wow…

The increase in “black space” instrumental separation with vocals
well delineated is way much better. Back up choir vocals appear as though layered on risers well beyond the 8’ wall behind my Aria 948s. Out of nowhere crisp clear images with richness…no sterile qualities here.

The Orange fuses add and improve on the blues by quite a bit (my .02)
with “body” that the blues only suggested.

In the overall it is as if I had upgraded every component significantly.
However your mileage may vary (ymmv).

I would venture to say that without a PS A regenerator much of these
improvements may not occur as it has with my system. Thusly
because not all have PS A regenerators results will likely fall
short of my results…Clean power is the foundation for good
audio…

Would my system with the PS A Quintessence have yielded as much?
It made a great improvement yes…but not on the level of my P5…
which later traded in for a P12…The P5 took my system to new heights,
and the P12 much further still…

Then came the Oranges…

So for me in sq here is my experience with the following fuses

I started with HiFi Tuning Supremes on my amp and P12…impressive results.
Then came the SR Blues a lot more detail.
Finally the SR Orange fuses…tops them all in every area…

Again ymmv…

Hope this helps shed some light on the topic…
Happy tweaking all

Have you gone back to stock or previous fuses to compare?

Thanks Brett …Yes…when running HFi Tuning Supreme and the SR Blue…Night day difference no going back…

How are yours coming along?

Each day is more involving, more ‘wow, that sounds good!’

I run the experiment going back to stock fuses on my BHK 250 in a few weeks just for the academic exercise and it’s easy to get to the back of the unit.

I have a Blue in my BHK preamp and a Ultra beeswax in the DS and Audio Horizons something in the P10. All made improvements. All purchased used at significant discount other than the Oranges purchased on the 2 for 3 deal last month.

In each case with the SR fuses, S towards the back and R pointing into the device sounded best to me.

Brett I understand the beeswax to be very very good…
when your oranges turn the corner…give us your .02 on
beeswax vs oranges

Thanks friend

Brett I didn’t read fully that your beeswax is in a different piece of equipment…and therefore can’t switch between them…

Yeah, I can swap the Orange 2A for Blue 2A in the pre though. So far I think the 6 in the 250 made the most impactful difference and they’re new. I factored in the cost of the fuses with the amp as it added 12% to the spend.

All of the others were, hey let’s try it and the price was right as others upgraded.

Way to go brett…
Amazing how such a “little thingy” can do so much…my oh my…

How about the beeswax can you swap with orange ?

Yes but the DS is a hassle to open…and it takes away from listening time!
