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.

gigaset,

I found that the Blues shifted into a decidedly "relaxed" mode after 7 days undisturbed. If you judged them before the 7 days, you might consider trying them again.

I installed my Blues into my amps.  Initially it was similar in effect of using the Blacks after they were broken in times 25%+.  I liked the flow of the music better with the Blacks for the first 45 minutes.  Then I listened for another 3 hours.  The Blues became so much better than the Blacks.  It wasn't just the increase in resolution, spaciousness, openness, it became like the Blacks, more intimate sounding.  The tone of instruments are now fuller than the Blacks. 

This change was similar to my change from my IC cables which were the same except for the reduction in capacitance by 50% by adding a teflon sleeve over the positive wiring.  See http://www.groverhuffman.com/home for details (his cable already incorporates a tri-metal powder based shield with a copper mesh outer shield).  It was a major improvement resulting in extended frequency definition, spaciousness and dynamics.

The result of using the Blues is so much more information and enjoyable listening.  Not just for me but for my wife and visitors who can sit five feet from the sweet spot on either side and enjoy nearly the same sonic features as the sweet spot.  (My wife had me get rid of my large electrostats 18 years ago after we married due to their limited dynamics, bass and listening space-center only).

I'm so glad that SR listened to my suggestion (if they did) that audiophiles would pay extra for broken-in fuses rather than burn up 72 hours of tubes to break them in.  That the price is only $20 more than the Blacks is greatly appreciated.

I found that after a 1 or 2 hours, they were eminently listenable and certainly relaxed sounding.  They're a great addition to my primary sound system.  I rarely use my secondary system and still haven't broken in the amp's Black fuse after 25 hours use.  I may purchase a Blue fuse just so I don't have to wait any longer.

I have modified 2 computer power supplies to receive upgraded fuses using fuse blocks or fuse clips. The mod has achieved great results for quite a simple mod. It's absolutely worthwhile. See the pics from the thread below. 

The first pc uses the Audio Horizons Platinum fuse. The second pc uses the new SR Blue fuse.
