  so if a tube blow out when headphones plugged in with sounds playing will there be damage done to the amp or headphones?

 
Just like @vocalstrance said "Don't worry about it and enjoy the music."

Human fatalities caused by blown tubes are rare; and usually the person is elderly or sick anyway, so it's not a major threat.  Sometimes - not often - there can be damage to headphones, but since tubes tend to give warning signs before they blow, you have a chance to replace them before you see fireworks.

How come valhalla 1 and 2 are about the same price on amazon when valhalla2 is the upgraded version. Lyr2 cost noticeably more than lyr1.

ok just got my valhalla 2. and i've tested low gain and high gain option with the k701. low gain provides a bigger soundstage it seems.
sorry for the double post.
bass doesn't seem as tight as i like them to be. hopefully that'll change with burn in.
what gain setting do you guys use with your hd6xx series?
can i switch between high gain and low gain when the amp is on or do i have to turn it off to change it.
if i can switch it while its on i can make easier comparisons between headphones and gain settings on them.
just trying to fiddle around and see what i like.

You can change the gain while the Valhalla 2 is on, BUT turn down the volume first. A loud pop will sound through the transducers if you don't.

Agree with the first sentence. But not the second - in my experience, there's no pop at all. You can switch the gain up or down while playing headphones, no problem.

well regardless if there will be a popping sound or not, turning the volume down seems like a good idea and ill follow that advice. and also how long does it take for tubes to settle in to their permanent sound?
so far theres this glare somewhere on top and it doesn't sound very dynamnic compared to straight out of my m9xx.
also noticeably not as smooth as my m9xx.

Hey guys.
I am going to use Sennheiser HD 700, 150 ohms.
Would hi gain work better than low?

You can try the low gain first for Sennheiser HD 700. I found the low gain works OK for my HD 650 (300 ohm), but I definitely prefer the high gain for the Beyer T1 (600 ohm)

AKG K701 is a challenge for Valhalla 2.

 

[EinZweiDrei]

yea it seems so. 180mw into 50ohms compared to m9xx's 650mw.
ill do further testing with my hd600 and hd650.

Does your guys valhalla 2 power light still light up when you turn the power off?
My valhalla light still is on and it turns off like 10 min after.
I even unplugedd the power plug and still does this.
Is this normal?

Yes, normal!  Not a malfunction.

It is normal. The led light is very efficient and the caps in Valhalla 2 hold quite amount of energy.
