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.

The only reason a fuse may sound better after it’s replaced with either the same standard one or "snake oil one" is because of ageing, too may turn on cycles will age any fuse, a $2 one or $150 one, and cause it to deteriorate. All explained below.

Buyers with little or no technical knowledge should not listen to any "snake oil" reasons here, as they are not backed personally on this thread by Synergistic Research, with the same outlandish claims that are made in this thread by the "awesome foursome" in regards to sound quality and direction-ability of these fuses.

Mapman inadvertently is agreeing with what really happens to a partially melted fuse, it’s called ageing. Good for you.

Funny this should be mentioned as it’s just like what happens to a fuse that’s seen too many turn on cycles, as there’s far more inrush current goes through it at the moment of switch on than any other time, as it has to charge up empty power supply caps ect. that’s why fuses and light globes blow (if nothings wrong) at time of turn on, here are some pics of fuse ageing.

I am not an electrical engineer (civil) but I do know the best electrical conductor is pure silver, then pure copper. What is in Graphene to make it change the effect of AC current power cable, fuses, speaker cable etc all of which have different cable and current properties?

I need to have something I can understand. TC sounds like woman's cosmetics. you can put any of the brands on and skin moisture properties change, but does not stop wrinkles. Cosmetics are the worst of the fault "science" perpetrators.

The passage of a signal, be it electrical (or traffic as in cars), will only be as good as the worst juncture, cable, component as traffic flow is as only as good as the worst intersection. I just cannot understand a change in "performance". Only a change in the travel condition, or as it HiFi, is the sound. It's only as good as the worst point.

Adrian,

That's what got me interested in upgraded fuses. It made sense to me that the thin wire in a fuse would be a bottleneck, or weak link. We upgrade power cords, interconnects, speaker cables, connectors, internal wiring etc. but there's still this chintzy little wire in the path, pretty much required for safety reasons. I don't know how SR does it, but they have certainly found a way to make that link less weak.

I fiddled with my speaker placements and angles following some prudent advice from the 'Gon and I am hearing new sounds from different angles and no goo or additions. So far, "a rickapoodi an' a fandoogly"; (that's great in non Oz speak).
