mine is one minor problem on the magni with RE-400, whole lots of static, perhaps the RE400 is just too much for magni?

^^ Maybe it's that the magni is too much for the re400. :wink:

Being both my first dedicated Dac and headphone amp, I am blown away by the sound. I'll have to start tube rolling soon too!

Out of curiosity does anyone know the output specs are for the preamp output on the Lyr are?  I'm also curious as to the volume setting used on the lyr when outputting to something like a receiver.  I just hooked up my outputs and find 12 o'clock to be fairly good with the bifrost usb as the source.

Does anyone have experience with pairing the Asgard 2 with Fostex TH600? It seems like everyone who has these headphones reccomends some fancy expensive amps, but nobody can comment on how it sounds with A2. It's a little frustrating.

While not exactly the same, the A2 seemed fine with the D7000 (or maybe it was D5000) that I tried at a meet. They weren't my cans so I can't give you any super detailed information, but it seemed like a good pairing if you like their sound sig.

I figured I would reach out to the collective genius that is Head-Fi before I bug Schiit with another question.

 

I received my Valhalla a couple of days ago and I really like it in addition to my Asgard.  My setup is as follows:

iMac to Bifrost via USB.

RCA splitter to Asgard and Valhalla.

All devices share the same ground.

 

I do notice that I have a very slight ground loop hum but it's only noticeable when pushing both volume pots past 12 o'clock, which is far beyond safe listening.  With normal listening it is unnoticeable, however this is not my issue.

 

The issue I am having is that the right channel of the Valhalla has a random and subtle noise.  It sounds like a faint but dull crackle or even static.  It may persist for 2-3 seconds and then go away for 5-10 seconds only to come back again.  This is not the same sound as the higher-pitched crackle of the tubes warming up or cooling down.  It exists whether the unit has any input connections or not.  I also took out both sets of tubes and switched the right and left channels and it still exists solely in the right channel.  I do not hear any of these noises with my Asgard.  Lastly, I do notice it with all of my headphones.

 

Any thoughts on what the culprit may be?  It's obviously not a bad tube.  Could it be RF pollution?  Could it be a bad transistor or an overly sensitive item that is picking up DC current from my ground, but only manifesting itself in the right channel?

Woot, they have the Lyr/Bifrost in black!  Just ordered.

Due to the overwhelming response :p, I shot an e-mail to Schiit to see what they think.

RF interference and ground loops are the most common problems with Schiit, but the fact you only have issues in one channel, sounds like the amp may have a problem.

That's what I thought.  I'll await their response and see if they can offer and other debugging techniques before I ship it back.

Based on what you describe, you have isolated the issue to the amp itself. You have eliminated all the other possibilities. If it were my amp, I'd email Schiit and describe what you did, and request an RMA.

I purchased it from Audio Advisor (via Amazon) so I requested a return.  I'm a little bummed, but looking forward to getting a replacement.

Great News people the VALI is up on Schitts website and ready to order.
