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.

Nonoise actually religion has absolutely nothing to do with it
That was never implied. It was meant to be analogous.

...the measurement and comparison process should be repeated multiple times...
And so too should hearing tests be blind and repeated multiple times in order to determine reliability of listener claims.

I believe that the main point Mapman was making about attribution of differences that may be measured in the proposed test was simply that the measurement and comparison process should be repeated multiple times. That would presumably eliminate the possibilities that the measured differences, if any, are the result of imprecision or lack of repeatability in the test hardware and/or software itself, or are the result of extraneous variables such as differences in the warmup state of the equipment.

That makes a lot of sense to me, especially when the measured differences can be expected to be small.


Actually, repeating the test doesn’t necessary make it more valid. The same mistakes that affect the first one, assuming there are any mistakes, would affect the rest of them. That’s why “repeatability” means having a totally different test and test conductor. That should be pretty obvious. Otherwise unscrupulous or uncareful test conductors - even careful test conductors - could have unfortunate consequences. Mistakes in a system may be beyond the control of the test conductor. So, any test result is only a single data point. It has little meaning if the test results are negative because - as has been pointed out a number of times - there are many reasons why a test might fail to show differences, or audibility or wherever was being tested when in fact there are.

NoNoise,

Also just to keep the record straight, I personally value quality accurate metrics as much as anyone in general but also acknowledge measurements are often not enough to provide the absolute final word in practice.

In response to clearthink…Obviously I know wires, tubes, et al have easily explainable benefits, and I hear those...it's the utter lack of any sort of explaining how or why designers decided that $2 fuses are inadequate, although the cheap fuses might be working well and your rig sounds fine. Does replacing an inexpensive half inch passive wire (meaning it's just wire that melts if needed) in a glass tube with a somehow improved half inch tiny wire in a glass or ceramic tube with graphene coating or special end caps or tesla coil jolting providing 75 times the benefit of the standard fuse?  Did the thousands of special fuse purchasers hear a difference or just assume there would be one because they're reading hyperbolic posts? Can't say, anymore than anyone can say the thousands of people not buying them are against improving their rig. Many supporters of Blue Fuses already are using tweaks that are questionable as to their efficacy, and seem to be bound to support any imaginary tweak that comes along…and in the case of Blue Fuses there remains no explanation as to how or why they might improve sound.
