Fuse Direction for Pass Labs Amp and Preamp


I am going to re fuse my Pass X250.8 and XP-32 with Synergistic Research purple fuses in a couple of days. I was hoping to get advice on a rule of thumb for direction of the fuses. My instinct tells me to start by installing the fuse by the direction of the lettering on the fuses. I am thinking that the direction should be the lettering left to right with the beginning of the lettering facing out of the amp and the end of the lettering facing into the amp. Does this sound right?

This is living proof of zombie threads coming back to life. Just try it both ways as there are no shortcuts and if and when you hear a difference, go with the way that sounds best to you.

All the best,

the idea that a certain speaker or amplifier can sound favor a certain genre of music.

You never owned Bose 901s or have read why Amar Bose designed them that way, I'm guessing.

Dear @mitchb : SR owner is a marketing " genius ". I own SR and other bs high-end fuses.

" People in fact do hear a significant difference between stock fuses and high end fuses. "

Of course we " hear " that differences because we already spend a lot of money and we " want " to " hear differences " where it can’t be differences at all.

Don’t spend your money but invest with for something that really can improve the quality room/system performance levels as room treatment.

 

Anyway, do what you think is the best for you.

 

" I redid the crossovers with high end parts "

 

that’s exactly as the SR fuses because does not exist " crossover high end parts ", only bs really inferior expensive parts for we audiophiles eager to go with. We customers are the " bu$ine$$ " in the audio world, especially for after market tweaks items.

 

 

Regards and enjoy the MUSIC NOT DISTORTIONS,

@russ69 This is such a great example of what I'm talking about (the myth bit)!

I'll put it to you this way: If someone comes up with a way to get home stereo electronics to favor a certain genre of music, they will be a millionaire overnight. There really isn't any way to do it (if you feel I'm incorrect about this, by all means, please get out there and show the rest of us your circuit or speaker design!!). What makes a speaker (or amp, cartridge, cable, etc.) good for one genre makes it good for another since we humans uses the same range of frequencies for music regardless of what the nature of the music.

Bose designed the 901 to mimic the concert hall, which might suggest to some that its better at classical music. It isn't. I regard it as a failure (insofar as accurate musical reproduction in the home is concerned; if meant to make money it seemed to be successful at that); at the very least there should have been more directly radiated information. The understanding of how the ear processes late delayed information was less understood back in the 1960s (if delayed about 10mS or more, the ear can use the rear-firing information for echo location, thus making the center fill more palpable; to do that the rear of the speaker needs to be at least 5 feet from the wall of the speaker behind it) when the speaker was designed.
