Synergistic Red Fuse ...

That is great news about High End Electronics giving a 30 day trial on Audio Magic Fuses. The owners Alfred and Betty Kainz are fine people.

^^^ Fine people indeed.  Their service is great too. I met Alfred at the Newport show this past June. We had a nice talk.  I was  hoping to meet Betty too, but she had to stay home to take care of the business.

Audio Horizons Platinum Reference More Than a Fuse

"Free Home Audition
We are so persuaded that you will be positively excited by the dramatic improvement the Audio Horizons Platinum Reference More Than a Fuse will make in your sound system, that for qualified customers we will prepay the audition freight to you. To qualify, one must have an Audiogon score of 30. Others in Conus can purchase the fuse on 15 days audition time money back guarantee."

"What Makes the Platinum Reference “More Than a Fuse" So Fine?
Without betraying proprietary information, let me note that the More Than a Fuse dramatically increases the impedance from 0.2 ohms to 10 ohms at 10 MHz, thus increasing high frequency noise-rejection fifty fold over that of a conventional fuse. As a result of this increased noise rejection, one can hear delicate extended high frequencies formerly swallowed up in noise.

And because the Platinum Reference “More Than a Fuse” also reduces ultra high frequency noise by up to 46 dB or more, a ratio 200 times that of a typical fuse, high frequency harmonic texture is heard against a dead quiet background with a level of detail and refinement so sweet, delicate, and with such presence and immediacy—well, it will make you smile."

cheers,

G.K.

Isoclean and Furutech fuses: yup, you guessed it, 30 day return policy. Have we forgotten anyone? Heck, even the Teleportation Tweak comes with a 30 day money back guarantee. Hel-looo!

While I don’t doubt that the Audio Horizons dealer twosome mentioned above are great people, and for all I know the AH fuses may be the greatest such product ever, I would hope that no one here will take this technical rationale to be anything more than ad copy.

I’ll spare everyone a lengthy discourse on the subject, as well as saving myself a lot of time, but suffice it to say that if the AH fuse provides better sonics in a given application than some other fuse, it will not be because its impedance is 10 ohms at 10 MHz. Also, a far more effective approach to attenuating 10 MHz noise, as well as noise at other similarly high frequencies, would be to put a suitably chosen ferrite clamp costing a few dollars around the power cord, near the IEC connector on the component.

And because the Platinum Reference “More Than a Fuse” also reduces ultra high frequency noise by up to 46 dB or more, a ratio 200 times that of a typical fuse, high frequency harmonic texture is heard against a dead quiet background....

46 db corresponds to a voltage ratio of 200x, so it follows from this statement that a "typical fuse" provides no attenuation of high frequency noise. I don’t doubt the correctness of that implication.
