Fuse Direction for Pass Labs Amp and Preamp

Tough day feeding dem der chickens eh !

PLUS 

I don't think a single person HERE is implying Atmasphere or the product he manufactures is anything but "Top of Line"

The notion of a “directional “ fuse is pure nonsense as is a “directional” speaker cable and directional rca’s…..wires….etc

Exclusively created and designed to prey on your audio nervosa wallet.

Cable is cable. Fuses are fuses. OAK is the only speaker finish. Class Ds suck. Why are you still using tubes? Concrete everything to the floor. Speaker spikes work. and the biggest of all, Come to AG and get a blast from the past.

You might be interested to know that my LP mastering lathe, which was originally built about 1949, sat atop a custom table that featured adjustable points for feet. So the idea of the points that so many audiophiles use has been around a very long time.

You might also find this interesting: You can look at any amplifier as having a perfect amplifying element with a distortion element (nonlinearity) in series with the signal. Put another way the differences you hear in amplifiers is simply the distortion signature. Because of this, if you have the distortion signature of a tube amp and were somehow able to put it in a solid state amp, the solid state amp would sound like a tube amp. We discovered how true that really is when we were developing our class D amplifier, in which the non-linearities tend to generate lower ordered harmonics rather than higher orders, so it has the smoothness and lack of harshness you expect from a really good tube amplifier although a bit more transparent.

It is the distortion signature of tubes which has kept them in business so long after being declared ’obsolete’ in the early 1960s. But now you can get the same distortion signature in a solid state amp (although maybe 2 orders of magnitude lower, allowing for greater transparency) with the same liquid mids and highs.

We’ve encountered cheap fuses that are not worth using. A a good quality fuse like Bussman or Littlefuse is hard to beat: if you are trying to use a boutique fuse, the former brands should be your ’control group’. In 1990 when designing our MA-2 we recognized that fuses were a problem, so we use a different kind known as an FNM. https://www.eaton.com/content/dam/eaton/products/electrical-circuit-protection/fuses/bussmann-series-supplemental-fuses/supplemental-fuses-midget/bus-ele-ds-2028-fnm.pdf This is a physically larger fuse employing dual elements and a larger fuse holder that exerts much more pressure on the fuse contacts, which are also much larger. They and their fuse holders easily outperform any boutique fuse made today. We did this and also used dual power cords on each chassis to minimize the internal and external effects of AC power wiring.

So please take it that when I say the direction of a fuse isn’t a thing, its with the awareness of fuse effects going back over 30 years, long before there were any boutique fuses.
