Quantum Science Audio Thread

I have 2 reds. One in my Lumin X1 and one in my JL CR-1 crossover.

ozzy

i have only tried the red fuses. one i my vitus sia 025 one i my ayon s10 sig. they both gave me the sound i was looking for. big powerful rich clean clear. pleasant. i just want to keep listening.

Any folks using the Red or Red Black fuses?

I believe there have been some issues with spam bots posting on the forum, and that is the solution.

Forget traffic light show me topless!

What’s this, I’m not a robot, nonsense going on to post on audiogon threads?

Papa,

 

I had one SA outlet in the wall and changed it out to the Red. Small positive outcome. I still have it and May install it in my bybee  stealth power conditioner. Not such an easy task seeing the wiring on the outlets and positions are hard to change out.

So far, I’m finding the QSA Stones to be the best value for for me in their line. The trick is to use all three colors together, and put them in places that have strong EM fields, like on top of power and signal transformers.

@glory 

"Sound application outlet."

I'm using the Sound Application Power Conditioner. Did you just change out one outlet? 

By the way, I pasted the entire inside of the unit with Total Contact. It took an entire tube to do the job. Super improvement in SQ.

Frank

Sound application outlet.

 

yes

@glory 

Which outlet did you change to red? Have you tried a fuse for a dedicated line?

I have the Red outlet. 400 hours to break in. Good results but the fuses are killer.

 

I have active Manger S1 speakers and they take two fuses each. TG only had two Yellow fuses on hand and I installed one on each speaker last night. Very huge SQ increase. May now go 4 Red.

Anyone else besides myself and millercarbon tried the QSA stones? What about the outlets, has anyone tried those?

Some of you folks may have fused speakers like my ARs. Have any of you used QSA fuses for your speakers? Curious about your results.

Also, have any of you QSA fuse users had a fuse blow?

Thanks!

I got 3 Light Blue fuses:

1 for my Amp

1 for my Paul Hynes SR7T

1 for my Paul Hynes SR5T

The sound changed from Very Good to AMAZING, HUGE, real and addictive, Yes I know a lot of folks dont believe in fuses or even wall receptacles, they do make a difference but in the case of these fuses are MAYOR / BRUTAL.

I wonder if upgrading the Yellow line worth the price jump over the Blue Light ?

Miguel

Can anyone give me an idea of how much, and what kind of, improvement you get going from a blue fuse to a yellow one? I'm contemplating another QSA purchase, and trying to decide between a yellow fuse upgrade from blue in one of my components (probably the amp), and another set of 6 stones.

Would love to hear from MillerCarbon in relation to the Yellows.

Thanks. Starting with factory fuses a few years ago I went first to Synergistic Blue and then Orange. These were in my Melody integrated, now Raven Blackhawk. Also used in the Herron phono stage. Haven't tried fuses in any of my subwoofer amps or CDP.    

QSA Light Blue was more clean and clear than Orange. Was quite surprised how much better. This is what I would call the signature characteristic of QSA, this clarity of detail. Individual instrumental threads stand out with lots of air around them.    

Even more so with Violet. This QSA Violet is so good that after hearing what Frank had to say about SR Purple vs QSA Yellow I can't see any point in comparing. Violet will trounce. As it should, seeing what it cost and all. I would sure hope so.   

The contest is between SR Purple and QSA Yellow, as they are real close in price. Unfortunately I haven't had time to do a direct comparison like Frank has. My Yellow only went in a couple days ago. Last night we were without power. WA, like CA, is run by boobs who don't want anyone to have power and so guess what? A lot of us don't! You will have nothing, and be happy. Right.   

Where was I? Oh yeah, Yellow. Mine went in the Herron. That thing has so many tweaks and mods I can hardly get at the fuse holder any more. So many tweaks, even my tweaks have tweaks! This is when I remember oh yeah, I painted the SR Orange with Krissy magic, and coated the ends with TC. Krissy magic is $60k/gal Rustoleum, dang I forgot about that, not exactly a fair fight. Oh well.  

You know its good in my system when it sounds good right off the bat, don't even need to warm up to hear it. Yellow was like that. First track sounded better than the last track the night before, when everything was nice and warm. I listened to Yellow a couple hours and it just kept getting better and better. Of course I was paying special attention to the midrange since that was Franks problem area but never did hear anything even slightly concerning there.   

First thing that hit me, aside from that trademark clarity, is a huge improvement in the bass. Lots of bass notes I had thought had real good articulation now had a simply astounding amount of tone, not just pitch definition but real character, more like I would associate with guitar or violin than bass. Really, really nice bass! Top end extension is excellent, and I just can't find anything to complain about in between.  

Was planning on running Purple head to head but just don't know that I will bother now. My sense of it from what Frank said (and experience with other SR) is their Purple will be just a tad smoother/warmer and the Yellow just a tad more pristine.  

I just don't see how you can go wrong with any of these. Everything from SR Blue all the way up to QSA Violet, they are all so good it is really hard to believe all this is coming from 1" of fuse. But it is.   

One last thing, if you buy Purple it is their top fuse. You can return no questions but there is nowhere higher until they come out with their next one. QSA has the same no-questions guarantee, but Mike also gives you 90 days to trade up with full credit. Which you might well want to do. I did. 

Would love to hear from MillerCarbon in relation to the Yellows.

I have all yellow QSA fuses.  I would love to hear from anyone who has purchased a QSA red.  Is it worth it?  What improvements did you hear?  Were you able to distinguish a difference in placing it in only one component?  Which component?  If I upgrade I am thinking the Lampi Pacific.

Sometime today, the old prototype fuse thread was removed. So, I started a new thread that was specifically targeted to those members who are trying the new SR Purple fuses. That new thread lasted about 30 minutes before it was also deleted. What gives? Are fuse discussions verboten now? Would someone please explain?

Something does not seem right here. I suggest you contact the moderators directly for an explanation. Please keep us posted.

Here is the link to pictures of the direction of fuse insertion

https://quantum-science-audio.com/

Its the top picture. Look at the top right hand of the picture. It clearly shows you how to insert your fuse for right direction 

Have got the direction of fuses all worked out from pics on QSA site for standard fuse holders under or above IEC plug.

But what about screw in fuse holders? Do the arrow of the fuse point inward or outward of the equipment?

cheers

@willgolf. You’re correct about left to right direction, which seems to be an industry standard, or at least the way the lateral under-plug holders are typically wired (I’ve asked and the answer is always the same). If a fuse is in the wrong direction, the sound will be closed in. The difference is readily apparent, even with a new fuse. Always worth checking if in doubt, as I received an SR Orange with the label on backwards. Even nondirectional fuses will often develop a better sounding direction with use.

@Ozzy On first application on a USB cable, the NPS-1260 does seem like the real deal. Hadn’t thought about putting it on a fuse, but it does make sense, if it can be made to hold.

I already used this idea with my own S.G. at no cost few years ago ...

I use agate,tourmaline Herkimer diamond and my "golden plates"...

😁😊

Very happy with GEMSTONES from TweekGeek.
Coincidentally I have five Shumann Resonators,
so each unit now has one stone of each flavor.

It is as if the sound is tranformed, meaning everything
positive gets a boost: lower noise floor, greater transient
speed, better placement of instruments in space, etc.
I hear no negatives.

I left the strips of five in place initially, and placed them
in my "open" circuit breaker box.  Not wonderful results,
but I have a Gate in there and other things that may have 
been interfering... Also struck out inside the rear of an open-cage amplifier.  Near the power switch of a Synergistic Research
Powercell 12 was slightly better.

The GEMSTONES are very very small, best handled with tweezers.
I bought a roll of double-sided foam tape and cut sqaures that
were just slightly  larger than the stones.  This helped with seeing them
and getting the stones to stick easily, without disturbing their backing.

It really was fortunate that I thought of the SGs.  It might be an
advantage to treat one kind of application rather than placing
then in different areas at the same time, which is something I have 
not done.  I am happy with my first complete set and likely
will not explore further.

BTW, I found that all three versions, mounted together, were much more
satisfying than just using the clear stones by themselves. 

These GEMSTONES, as a complete set, are pretty impressive,
in my opinion.  They truly impact the music.

So you wouldn’t be losing any monies on the QSA fuses and still be able to get the SR Purp and have the benefit of another affordable tweak with the QSA stones? I’ll never know until I ask. Thanks for making me think about this.

And this is Mike's response:

'Not really. I would say the fuse upgrade has more bang for the buck anyhow.'

That's not a yes, or a no.

Aside from the fuses, can anyone who has tried them comment on the AC outlet or the "stones"? I have a blue fuse in my Decware amp and am planning to order a yellow fuse for my DAC.  I regret not taking just splurging for the yellow for the amp :-(Chris 

docknow,

I know you can trade in/up the QSA fuses to purchase other QSA fuses, but was wondering can you trade up/in to the QSA stones? We maybe able to trade in/up to the QSA stones?

The red were the first stones I tried and the only placed I liked the difference was inside the breaker panel. I agree with Miller that the other two types made a bigger difference in my system. 
But if you’re not getting anything from the red then maybe best to send back.

Can't argue with that. I found red to be the least impact, with only a very small improvement in making the sound a little smoother or more liquid and very slightly deeper. Maybe good for someone with a lot of SS or digital or anything wanting a bit less glare or grain. 

Blue was more obvious, and Clear most of all. Any one alone could be used to fine tune a system without changing anything too much. All together, which is how I'm using them, I found the combination to be fairly well balanced. 

QSA fuses are a sure improvement. But I question the stones. At least only one pair of red on my power conditioner, preamp power supply, and amp transformers. At least on my system... nothing.

Yes, they are lined up L to R across the top of the transformer cover. Not the prettiest things it would be nice to find a better location but the sound the other night was so good, Sinatra-Basie always a good one but after putting some hours on the amp watching Free Guy and late at night OMG so incredibly good!

millercarbon,

I believe you put the QSA stones on the output transformers of your amp? If so, did you leave them there? I’m considering getting another set of all three, and that’s where I’m thinking of putting them.

I found Frank's post about the Prototype and then SR Purple to be quite valuable, as it kept me from purchasing a QSA fuse, that I then might have had to sell at a loss.

@david_ten @tyray 1+. Yes. That is what we are here for sharing info, experiences both good and bad with music, gear, vendors, websites, reviews and whatever. I feel that Frank was providing our community a valuable service and I want to learn more about how the beta SR Purple stacks up against its competitors. 

tsushima1, Thank you

Ignore the negative posters and they will slink back from whence they came and hide behind the moniker they’ve created here to just bully others as they have nothing positive to give, or anything better to do.

Amen.

+1 leicachamp on both of your posts

@oregonpapa   Frank, looking forward to your thread. I personally do not see any issue with you posting your experience prior to their availability. I encourage you to start your thread whenever you choose to.

There are many threads that provide early impressions and full on reviews prior to those products / components being launched.

@tyray  +1 

leicachamp ...

I have no problems with what was said. You made some valid points.

I appreciate tyray’s positive comments as well.

When the SR Purple fuses are released, I’ll start a new thread. They are way too good not to share information about them with other hobbyists.

In the meantime, enjoy the music.

Frank

Tyray

i hope you are not referring to me as being a Bully.

Frank was wondering why his threads were shut down. I just gave him my thoughts on why his was shut down while this thread remains open.
