Anyone used these audio ceramic slow blow fuses from Littlefuse?

Those who engage in bias confirmation are not critical thinkers. Don’t endorse a view simply because it’s consistent with your belief paradigm. It’s lazy thinking and wastes everyone’s time who read your post.

Oops...hypocrite revealed:

“The RM-10 MK2 has improved output transformers which yields lower distortion at the higher frequencies and midrange, resulting in more detail. The RM-10 MK2 also features larger binding posts, which are now 1/2 inch. High quality components (such as Dale resistors) have also been incorporated into the RM-10 MK2.”

I presume @ramtubes does not use premium resistors, capacitors and tubes in his designs. If he does, then he’s a hypocrite.

Call me biased. Wire is wire, regardless of implementation. As long as a wire passes electricity, it’s in play. Electronics theory doesn’t get much simpler than that. 

Here’s another guy who believes audiophile quality fuses make a difference.

Word on the street is that Littelfuse
will send out free samples to those interested. The lot codes for sample orders come in increments of 100 and 1000. But the rumor on the street is that they will send out singles based upon whatever one inputs into the quantity window (that is, don’t expect to receive 500 or 5,000 fuses if one inputs "5" into the quantity window for the corresponding product lot code).

The 285 ceramic tube, slo-blow series identified in their product catalog as 0285001.HXP corresponds to gold-capped fuses having a 1A rating and a description: FUSE CERAMIC 1A 250VAC 5X20MM.

The 285 ceramic tube, slo-blow series in their product catalog as 0285001.HXRP corresponds to rhodium-capped fuses having a 1A rating and a description: FUSE CERAMIC 1A 250VAC 5X20MM.

Please post here those who opt to order some fuse samples for testing and let those here who care know of your results.

Nonoise, the original poster (RAM) of your copied quotation is an accomplished audio designer, for what it’s worth. So it’s surprising that he would simply write off the notion of fuses having an audible characteristic based upon only theoretical considerations. I don’t know if he even listens to his designs before they head out the door. The vague suggestion from the designer is that if his product designs should sound superior based upon theoretical considerations, then it must be true in reality. 

By contrast, Paul McGowan of PS Audio in the above YouTube clip came to the conclusion that the fuses have audible characteristics based upon listening sessions, where some “sounded better” (e.g., less grunge, greater clarity and openness etc.) than others. While Paul admitted he didn’t understand why such is the case, PS Audio include fuses having better sonic qualities in their products. 

And on the assumption one can find a supplier of those Littelfuses (Mouser and DigiKey don’t carry them), they are $8-$10 per fuse to the customer, plus tax and S/H. 

Lol. Free is free. Whether it’s the fuse or the editorial corrections from the cheap seats.
