The guy who modded the Yggdrasil (necessary?)

Hi everyone, just found this article: http://www.tweakaudio.com/EVS-2/Schiit_mod.html
Looks like a slightly minor mod. I don't think it's necessary. (Not a tech guy, anyway.)

 

This guy has been posting various mods on HF. He is an absolute nutter! This guy is mad - ignore!

 

Saw it a while ago, but probably not worth voiding schiit's 5 year warranty for.

 

I wouldn't go so far to say he's nuts, but I do not plan on implementing much or any of his suggestions. Maybe a new fuse after warranty or asking Schiit to do it whenever the first upgrade comes out. (Had positive results switching out my stock Maggie fuses with <$20 AMR gold fuses.)

I looked at his mods for the Oppo 105/D, but the shoddy looking quality of the wiring turned me off. I also cannot figure out why those quantum stickers would do a lick of good on top of capacitors, especially all cut up like in the new Yggdrasil photos...

 

Bypassing a fuse can actually make a major sounding difference. Think he is on to something big.

 

The guy is nuts or has quirky sense of humor.

 

So, you guys couldn't simply say "I'm Ok with the Yggdrasil" ax is without making "peanut gallery" comments as to the worth of the Mods,or whether the Mods are "necessary" (that had me LOL ) & the funniest was the one referring to Ric Shultz ad a "nutter"

I have a feeling that what I might consider as only "decent" sound , some of you might think of as your new "listening standard" . (Thanks for the "chuckles", though

 

Actually the guy who moded is not Shultz, I emailed Shultz last momth.

 

I didn't say it but advocating something as dangerous as running an electrical appliance without the chassis qualifies as nutter in my book.

A lot of the rest of the site seems like audiophoolery, if you think it improves the sound quality, great, but don't ever do any blind testing.

 

some googling does seem to indicate EVS is Rick Schultz. his amp sounds pretty neat based on parts http://www.tweakaudio.com/EVS-2/Class_A_amps.html

 

I personally, also don't use a Yggdrasil, I'm using a Metrum Hex.

I agree that It is a tremendously bad idea for anyone who doesn't understand what kind of dangers are possible working on the insides of an Electronic circuit, should not be attempting to modify anything that is beyond what their Knowledge / Skillsets of the task at hand. ,

You can however , try to implement "tweaks" , that are less invasive . Common sense (which unfortunately is becoming an vanishing "concept") should rule the day. I don't think I'd be comfortable removing a components circuit from it's chassis & just
running it in the open as often as I rearrange components


Beyond that , it is extremely rare that I attempt things that are non-reversible . I'm pretty certain that "Audiophoolery" is just a mind-set that everyone has to define for themselves ! ( My skepticism of anything iis always tempered by how much control I have over what I'll attempt)

 

I lol'd so hard when i got to the picture about the "capacitor chips". I'm going to assume that this is a troll mod as a result. No sane person could possibly believe that a plastic sticker can do anything right? Please....please tell me no one believes this.

Also, could someone please explain to me how "dampening a heatsink" is supposed to do anything.... The only even vaguely vibration sensitive component in a solid state circuit is the crystal. And that is really vague... ugh.

 

Naked is good, I'll give him that.

 

It's super simple. Mods void the warranty. The product will have to be returned to stock before service. That can be a very big bill. You roll the dice.

 

I particularly like how the 'solderblob' smeared over the power switch is only separated from the safety ground by the soldermask.



Just as stupid as by-passing the mains fuse with a piece of foil.

 

If I may put on my tin-foil unicorn hat... From a heat sink we want a smooth laminar convective flow for maximum energy transfer. Micro-vibrations will induce vortices and turbulence, which inhibits and thus slows down air flow. Such vibrations will also impeded the formation of a steady state system, and prevent the heat sinks from reaching a stable equilibrium point.

C'mon guys, I've got a degree in this stuff. That means I'm right eh?

p.s. let's just ignore the fact that the damping material is covering our conductive heat sink surface and reducing its ability to transfer heat to the air in the first place...

<Neglecting your tongue in cheek answer and pretending temporarily it was serious>

Actually, turbulent flow is significantly better for heat transfer as you get mixing between the boundary layer and bulk fluid. Boundary layer formation in laminar flow inhibits heat transfer.

How does this guy even know if the mods have had the desired effect??
The Acoustic memory is very limited ...
You really need to have two DACs for before and after ...
