Schiit Valhalla Tube Rolling thread.

[Lvivske]

The fuse for the Valhalla II is: ‘small’ (5x20mm), ‘1A’ (Ampere), ‘T’ (Timed a/k/a Slow). To replace the fuse will require removing tubes, unscrewing all the screws, taking off the volume knob and related nut/washer, sliding the PCB out to access the fuse clip…

no prob i've been gutting amps lately

is there a reason you're on this brand in particular?

edit: hifi tuning supreme seems to have the "aug/ag" type (silver color) and the "cu" type (gold color, 'warmer' in description)

I have used this brand and Synergistic Research. The HiFi Tuning product description and manufacture caught my attention (cryogenics etc)…

EDIT: Amps have been gutting your wallet…

I've been bargain hunting

The Synergistics, did you try it out yet? The RED model has an interesting description ("further refinement, with smoother highs and more linear frequency extension.")

I replaced the fuse in my Lyr3 with Hifii Tuning some time ago and as I recall the sonic improvement was noticeable. Slight but improved. Or was that expectation bias? Schiit, I don't know.

If one notices an improvement, whether real or perceived, does it really matter.

(Hmmmm. I wonder what type of fuses are in BF2 and Ragnarok. )

 

[Lvivske]

$100 for a slight but noticeable improvement is pretty choice by audiophile standards

 

[Ripper2860]

True. But the best investment with the greatest impact could be had for as little as $50.

 

[Lvivske]

will it make the voices go away?

Since the electricity has to go through the fuse before other “innards” of a component, the more electrically transparent (the fewer any spurious byproducts from) the fuse, the more effectively the component is powered.

I have SR Orange in Woo WA2….nice! I have not (probably will not) A-B test Hifi Tuning vs Synergistic Research. Of my h/p/a, some (will) have HFT, others (will) have SR. Rolling fuses is not what I envision.

 

[Ripper2860]

No, but they will have a much more vast soundstage, improved imaging, and a tad more air and space.

 

[Lvivske]

interesting thread on the topic (1 guy thinks SR is relabelling cheapo fuses?)

https://forum.polkaudio.com/discussion/comment/2651972

might just look for the lowest cost HFT Supreme I can find and give it a whirl, though the SR Reds are on sale for like 60ish....flip a coin

my Val is over 10 years old so maybe I'll justify it to myself on that

That's true only if the fuse filament is made of SPOCC wire.

Paul endorses the Hifi Tuning, I'm sold



reddit, on the other hand (r/audiophile) is hating on this concept like no tomorrow (even accusing PS Audio of shilling fuses they dont make)

 

[G0rt]

All properly raised audiophile chilluns already know copper pennies make the bestest fuzes, and the 1909 S VDB sounds fine for jazz, and doesn't even need cryo to planetarily align Abe's atoms.

Just sayin.

Speaking of fuses. . . I have a Synergistic Research Purple fuse out for delivery as I am typing this, and can't wait to hear what my first audiophile grade fuse can do.

Having done a ton of reading and research, the SR Orange fuse has more positive reviews than any other fuse out there. Many times I have read people changing from the Hifi Tuning Supreme to the SR Orange and noticing an improvement, so I went with SR. The Purple version just came out a couple of days ago and is the new SR "Flagship" fuse, so should be even better than the orange. . .
