The new Synergistic Research BLUE fuses ....


New SR BLUE fuse thread ...

I’ve replaced all 5 of the SR BLACK fuses in my system with the new SR BLUE fuses. Cold, out of the box, the BLUE fuses stomped the fully broken-in SR BLACKS in a big way. As good as the SR BLACK fuses were/are, especially in comparison with the SR RED fuses, SR has found another break-through in fuses.

1. Musicality ... The system is totally seamless at this point. Its as if there is no system in the room, only a wall to wall, front to back and floor to ceiling music presentation with true to life tonality from the various instruments.

2. Extension ... I’ve seemed to gain about an octave in low bass response. This has the effect of putting more meat on the bones of the instruments. Highs are very extended, breathing new life into my magic percussion recordings. Vibes, chimes, bells, and triangles positioned in the rear of the orchestra all have improved. I’ve experienced no roll-off of the highs what so ever with the new BLUE fuses. Just a more relaxed natural presentation.

3. Dynamics ... This is a huge improvement over the BLACK fuses. Piano and vibes fans ... this is fantastic.

I have a Japanese audiophile CD of Flamenco music ... the foot stomps on the stage, the hand clapping and the castanets are present like never before. Want to hear natural sounding castanets? Get the BLUE fuses.

4. Mid range ... Ha! Put on your favorite Ben Webster album ... and a pair of adult diapers. Play Chris Connor singing "All About Ronnie," its to die for.

Quick .... someone here HAS to buy this double album. Its a bargain at this price. Audiophile sound, excellent performance by the one and only Chris Connor. Yes, its mono ... but so what? Its so good you won’t miss the stereo effects. If you’re the lucky person who scores this album, please post your results here.

Overall impressions:

Where the RED fuses took about 20 hours to sound their best, and the BLACK fuses took upwards of 200 hours of total break-in, the BLUE fuses sounded really good right out of the box ... and that’s without doing anything about proper directional positioning. Not that the BLUE fuses don’t need breaking in, they do. The improvement continues through week three. Its a gradual break-in thing where each listening session is better than the last.

Everything I described above continues to break new ground in my system as the fuses continue breaking in. Quite honestly, I find it difficult to tear myself away from the system in order to get things done. Its truly been transformed into a magical music machine. With the expenditure of $150.00 and a 30 day return policy there’s really nothing to lose. In my system, its like upgrading to a better pre amp, amp, CD player or phono stage. Highly recommended.

Kudos to Ted Denney and the entire staff at SR. Amazing stuff, guys. :-)

PS: If you try the SR BLUE fuses, please post your results here. Seems the naysayers, the Debbie Downers and Negative Nellie’s have hijacked the original RED fuse thread. A pox on their houses and their Pioneer receivers.

You are of course correct
It is just his one sided determination to derail this thread with bunkum that is depressing to say the least
Sad really I suppose.
I will attempt to restrain myself and just turn the music up......

No sorry, it’s giving the technically weak a chance to compare a side (dominated by the awesome foursome) that’s not at all technical and considered to be "snake oil".
To be compared to a side that has only presented technical merit, that a >$100 boutique AC mains fuse is no better than a quality $2 fuse.

If you have a tired original fuse because of too many switch on surges, all you have to do is change it for the same quality $2 one.

Fuse aging by switching loads

The fuse wire gets hot and expands when current flows. At high temperatures, oxidation may happen, which weakens the wire mechanically, and may be electrically, too. Switching on/off a load means the wire is bent each time.

Another way to look at this: a fuse is like a light bulb, the old type with a hot filament. Although very hot, it still takes some amazing 1000 hr to melt. And even at under-voltage, burning lower, it will not light ’forever’ and will get dimmer as resistance builds then blows, always at switch-on, that's why the new globe always seems/is brighter, even though the same wattage.

What about the fuses I’ve linked to that use powder to keep the temp down so it doesn’t age the same as the fuses you use? They’re readily available, cost only $4 apiece, and perform better. They’ve been around for many years and the technically proficient know of them.

It’s the type of fuse that aftermarket makes based their audio fuses on with an ear and eye towards bettering the sound, and admittedly, making a profit on. You don’t need to spend what SR changes unless you like the results you get as there are well made ones for a lot less. But to each, their own. Get a new hobby horse, George.

All the best,

Hey, put your ! cap on, I’ve got nothing bad to say about quality fuses for a couple of dollars, it’s all about the >$100 boutique ones, that bleed the gullible of their hard earned cash.

As I said before you wouldn’t get notables like the industries design "gods" like Nelson Pass, John Curl, Dan D’Agostino ect ect ect talking about fuses the way they are frothed about here.
And if those fuse froth’ers went to the sites like DIYAudio.com where they (the gods) hang out, and started talking about fuses they way they do here, they would get toyed around with then spat out severely once they tried of them.

As for sand/quartz filled fuses. It doesn’t make them sound any better. It also absorbs the energy when they blow and stops a big mess by most of the time not shattering into pieces..

" Current limiting fuses contain a granular filler, usually high purity quartz sand of a defined grain size and packaging density. The specific grain size distribution provides room to expand for the vapours and gases produced by the arc and offers a large surface for efficient cooling. The filler does melt under the influence of high arc temperatures, absorbing an enormous amount of energy and extinguishing the arc well before current zero. Fused quartz and metal form a non-conductive fulgurite body that prevents re-striking of the arc."
