Schiit Decrapifier released - USB power isolator - Page 4

post #46 of 271

Yea, master clock is an external crystal oscillator. Lower phase noise I reckon, and of course less drifting since the clock is 20ppm.

Any chance for a 230V version?

It's coming within a few weeks. I'm also waiting for one.

My MacBook Pro Retina Late 2013 has a slight issue in that I can hear the electrical activity of the processor as intermittent static coming through the USB port and into my Schiit stack (Gungnir to Mjolnir and onto my headphones / speakers). By process of elimination, I discovered that if I removed the MBP power supply connection the noise went away slightly, but not completely. And, it wasn't a ground loop issue as I would hear the noise only when clicking on windows and opening applications, basically anything that would require some increased work by the processor (or something related electrically). Otherwise no background hum characteristic of a ground loop. Hooking up my DAC via optical solved the issue but I prefer using USB.

Thus, the Wyrd seems to accomplish its simple mission of interrupting the transmission of this electrical activity noise. That's all I wanted it to do, so it was $99 well spent. I was also considering the iFi Purifier but decided on the Wyrd simply because it was made by Schiit.

EDIT 6.6.14 - Correction, I'm still experiencing the same issue. However, having the Wyrd connected doesn't seem to introduce any additional noise. Hopefully I can troubleshoot and report on progress later.

 

Did you manage to troubleshoot your issue?

 

I'm also facing a problem of hearing my HDD activity noise over my active speakers (this is especially apparent when using an external HDD via USB) which is connected to my GO 450 which is connected to my PC. I'm hoping the Wyrd can clean this up.

I thought the specs say the crystal oscillator is 20ppm??

Yes, I was incorrect as firev1 pointed out.

 

The USB repeater chip has an internal spec of 350ppm (as far as I can tell), but Schitt is not using the internal oscillator.  Instead it is using an external source (ASV chip) with the tighter clock spec.

I currently use an IFI purifier connected to my Belcanto M-link USB/spidif converter feeding a benchmark dac1. I was considering getting an IFI power. Do you think adding a Wyrd will help get better sound?
post #53 of 271

I'm planning to order an external USB power supply for my V-Link 192 USB - S/PDIF converter and my Audio-GD NFB7 DAC soon. After lots of reading and research, I've finally come up with the final 2 options: the Schiit Lyr and the iFi USB power supply.

 

Has anyone had a chance to own/compare these two equipments? I've read that the iFi is just a power supply, it doesn't 'change' or 'affect' the data signal transferred in the USB cable, whereas the Schiit Wyrd somewhat re-clock the data signal as well as provide a clean power for USB.

 

Which one should I go for? And what are the sonic differences ( if have ) between the iFi and Wyrd?

 

Thanks in advance,

Kratos.

Kratos,

I can not speak to the iFi Unit, but I own the Wyrd and have found it greatly reduces background noise/"hash" from the poorly executed USB ports. It provided an inky, black, very quiet background from which the music emerges, providing the impression of greater dynamics, tonality, imaging and sound stage. I am using the following configuration: Computer>Wyrd>Modi>Lyr 2.

Wow! Thank you very much!

 

I guess I know what I'm gonna do ;)

Can't wait:popcorn:

With the gungnir do I need the decrapifier?

Anybody tried this combination?

Many thanks
post #58 of 271

does it come with shorter usb cables or do we actually double the length of something that should never get extended(said the noobs who determined what USB specs should be, so they might know something)?

 

what about "event" choice in wasapi? wouldn't that be much better than to add another reclock in the middle for no reason and pray that it does good? if you have an asynchro dac what is the point?

 

now noise: if there is noise from your dac, get a good one instead? the only time I got computer noise passing a dac it was a 20$ hifimediy without an amp. be it my odac/o2 or my leckerton uha760 they have a perfectly clean background(and I mean perfectly clean, a dx50 hisses, a f886 does a "tac" noise every 2 seconds... I'm picky on that subject) and that whatever the crap I plug them into. laptop/tablet/phone.

Purrin has stated several places that it greatly enhanced his experience with the gungnir.

 

Schiit Audio has stated that they make no claim to the decrapifier making any difference.

 

In my testing so far I have heard no discernible difference, testing continues with multiple PCs.
