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.

@uberwaltz   Thanks, I was not aware of that. I must say that the SR's sounded better than the basic ceramic Schurters.  Maybe the Schurters will break in and improve (he wonders hopefully.)  :)

For those with technical expertise, how significant would a plus .25A value be?  Specifically, there are 1.25A Hi-Fi tuning fuses still available.  I can figure percentage but not "real world" difference. Thanks.

I have no technical expertise but due to availability, I went from a 1.6A to a 2.0A fuse and nothing untoward happened. It was with a PADIS fuse but I've read where others have gone up more than that with no ill effect.
YMMV and some here will admonish those who do it.

All the best,

I went from a 5 amp to an 8 amp fuse due to the size of my amp's storage capacitors.  They are huge at 7" X 3" pairs per monoblock.  The reason given by SR is that large storage caps cause a greater surge to fill upon startup compared to the typical multi-small storage caps used in most modern equipment.  My dyna 70 amp only required a step up from a 3 amp to a 4 amp fuse (although it's storage cap was replaced with one running the entire diagonal length on the bottom).  I remember that for my speakers in my video room, only the same small value fast blow fuses were recommended by SR.  I'm planning on replacing the video speakers so I didn't bother buying new fuses for them.

During a discussion with a well known amplifier manufacturer he recommended that I go one value higher with each stock fuse I was replacing with an upgraded (boutique?) fuse.

I owned an MGB in college. My buddy owned a Jag about 3 years later. Both were outfitted with Lucas electrical including headlamps and rear lamps. We came to appreciate 2 phrases famous in Britain:
1- Lucas Electrical -otherwise known as the "Prince of Darkness".
2-If Lucas made guns, the world would never be at war.

OK back to the thread.
