I am sorry, why do you think the Valhalla 2 blew your Beyerdynamic Headphone? I have never heard a report of a  Valhalla 2 damaging any 'Phones. Who is telling you this? Are you sure it isn't a Dealer/Manufacturer trying to avoid a warranty issue?

Sorry to hear that man.
Talk about a similar experience..just plugged my 880-600s into them and BAM a weird pop on the left driver..I pray to god everyday for the safety of my headphones when I plug them into the V2 or any other OTL for that matter.

  You mean you have same my proplem? with DT 800 

Not yet but at times I can hear the Valhalla 2 massage my headphone membranes.
I will get rid of it (Valhalla 2) soon.

The Valhalla 2 is designed to be able to be used with low impedance IEMs as well as high impedance headphones, so it is strange that you will have an issue especially with the ultra high impedance 600ohm dt990 that should be able to handle a lot more power.
 
I would contact Schiit customer service. 
 
Information from their website:
"Does this have a muting relay, like all your other amps?
No. The slow turn-on and turn-off characteristics of tubes and limited current capability means there's no muting relay—which is the same for pretty much every tube OTL headphone amp out there. While there is DC on the output at turn-on and turn-off, it is on the order of 100mV into 32-ohm headphones. If you are concerned about this, unplug your headphones before turning the amp off, and wait 30 seconds or so after you turn Valhalla 2 on to plug in."

I've had my older Beyers (880) have a driver go bad with other amps.

 

[Argo Duck]

^ Exactly. Sometimes a headphone driver goes bad. Doesn't mean the amp it happened to be plugged into made it happen.

Got my Wyrd yesterday. It dealt with the small amount of glitches i was having during playback but it did not help with mahusive amounts of glitches I'm having when my PC is turned off.
 
My chain consist of:
PC -> (Wyrd) -> uDac3 -coax> Argon DA-2 -> B&W DM685
 
One other thing, the powersupply i got with the Wyrd is basically unusable by me. It's louder than my PC, which consists of a Define R4, 1 SSD, undervolted fans a CUII 270X TOP clocked to schonk and fans speed at a minimum. It's bloody quiet so maybe not the fairest of comparisons. Though i can't stand this mosquito supply.
 
For $100+ i would have liked a properly working PSU though these little buggers do not travel that well so it might have gotten knocked in transit, who knows.

I should not make any noise at all. I think that power supply is defective. Should call Schiit and ask for the replacement.

Hey guys, was looking to order one of these amps and thought I'd get a second opinion.  Do you guys recommend:
 
Valhalla 2
-or-
Lyr 2
 
for the headphones in this collection:
 
Denon D7000
Senn HD 650
Phil. Fidelio X1
Hi-Fi Man HE-5LE
Mad Dogs
UE Triple-Fi 10vi
 
?
 
I'm leaning towards the Valhalla 2 based on recommendation that I don't need the power of the Lyr 2 to drive my cans well.  I'll be using my NuForce Icon HDP as the dedicated DAC. Thoughts?

 

[purrin]

HFM HE5-LE and MadDogs will like Lyr 2 better.
