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.

ARC tube power amp owners know (or should know) that the company made the engineering choice to not fuse their output tubes



Most good audio amps don’t fuse in this location or on the power rails save for a few PA amps I've seen.
But all ARC amps have fused mains, just like any other manufacturers.

Today it is starting to become common practice to do away with your everyday fuse and holder and also circuit breakers, because of the cost of these.
And in their place many now are starting to use SMD (surface mount device) fuses which are around 2-3mm long and soldered in. These are saving manufacturers around 80% of the cost of using fuses/holders and circuit breakers. (sorry no snake oil ones of these, yet?)

Apparently my Lyngdorf 2170 uses one of these types of soldered in fuses.

I am sure with just a tiny bit of work and ingenuity an aftermarket fuse can be engineered for these too.

One trusts surface mounted fuses can be reversed to check for directionality without a whole lot of angst and trepidation. 😩 Do they come with arrows? 🤡

One can google to see that some modders eliminate the soldered in fuse on their mods. OPPPMOD and Clones power supply boards do away with the soldered in fuses as well. Also, I believe OPPOMOD upgrades the fuse as well as part of their work, or it could be Clones (I forget).

Frankly, anything that can do away with the fuse, retaining the designers goals, while maintaining safety, would benefit everyone.

All the best,

Bdp24 I bypassed my fuses with solid silver 26ga wire for about a month. My amp was about 20 yrs old and I felt it was pretty stable in my system. Anyway it sounded easily noticeably better in every-way. So I got me some SR fuses and they sounded better than the silver wire. I don't know why. But I do not care because me likes it.
