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.

mapman .....Also slo blo fuses can melt partially and have an effect on performance and sound.....

gdhal This is interesting for me to understand, and something I wouldn’t have considered. Thanks.


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 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.

Thank you
@almarg

Always a pleasure to read from you in any thread and on any topic. Note that my question wasn’t specific to the OPPO though. EDIT: or an internal or external fuse.

In the case of the question I’ve posed, I’m inclined to believe what mapman has stated "it makes a better and more robust connection".

I remain grateful to everyone to be able to participate in this forum. Regardless of your opinions, beliefs, etc. about fuses and all of the other equipment here on Audiogon. Remember that it wouldn’t really mean anything without the music itself 🎵

Something we all can share and should find in common 🙂

Good lord George
Do you not have anything more in your repertoire than your standard 4 well worn responses that we have been "treated" to ,oh what a hundred times or more now?

Anybody have any new flash cards they can lend George?

The argument regarding the fuse on the Oppo back panel is a Strawman argument. Why, you ask innocently? Because in the previous models the fuse was located inside the unit, as it was in mine. Talk amongst yourselves. Smoke if ya got em.

I experimented with bussman and littlefuses as to their directionality.  I couldn't tell the difference between one or another direction.  There may have been, but it was too subtle for me to notice.  

As to SR fuses, their directionality is obvious.  It is equivalent to in phase and out of phase recordings and polarized A/C plugs.  Extremely obvious(!!) to my friends and myself.  I had no expectation bias when I first purchased the SR black fuse.  I had the fuse inserted "out of phase" on my first attempt.  Upon reversing the direction as per OPs' recommendation, the correct direction was obtained and "in phase" sound resulted.  

The SR Blue fuse is not as great a leap in sound (modest relatively speaking) compared to the SR Black fuse.  Anyone with an SR Black fuse should be enjoying enhanced sound in a good sounding audio system (low resolution systems probably not).
