That's good. I imagine most people's amps are quieter than mine, but I know I'm not the only one whose amplifier hums since others have mentioned it on the forums. It's not the tubes, I've tried over 10 and they all hum in the Vali and none of them hum in other amps. Maybe I'm more sensitive...

Schiit told me the hum is normal because of the design of the amplifier. I know it’s not the adapter as I said it happens with every tube I’ve tried and I’ve tried many. The GE tubes are just the ones that have the least noticeable noise for me.

My Vali 2 has hum as well. It’s there no matter what tube I use (although some make it worse than others). With high impedence headphones and low gain it ranges from barely noticeable to annoying but listenable. I gave up with low impedence headphones. I bought mine used, but Schiit told me this...

I only own The Boatman's call, so I haven't spent a ton of time listening to his other albums. I just listened to the 2011 remix on Tidal and found some older mixes on You Tube. The louder sound at 14 seconds wasn't in the earlier mix I found, but the softer crackling sounds before that were...

That noise sounds intentional me. There is an earlier crackling noise that pans from right to left and is audible in earlier recordings. Just from listening I think the noises are are supposed to be ruffling through a pack of cigarettes and the sound at 14 seconds is lighting the cigarette...

I'm not really sure how often B-Stock comes available. Keep an eye on the for sale /trade forum here, that's where I bought mine (and where I'll likely sell it at some point).

No adapter needed for a 6922. From the Vali FAQ on Schiit's webpage: But there are a lot of other options out there, including 6DJ8, 6922, ECC88, 2492, and even more. Pretty much any tube with a 6DJ8 pinout, 6V heater, and 600mA or less of heater current will work fine in Vali 2. With...

They do sound different, but they have a similar sound signature. That is to say they sound closer to each other than either does to another headphone. There’s also potentially some differences between any given pair of 580s and some may sound closer to the 650 than another 580.

Some force is normal, but you shouldn't feel like you have to "force" it if that makes sense. As others have said you might need to rock them back and forth a little bit. Also, hold onto the base when putting them in or taking them out (not the glass). If the base sticks, you can pull the...

Fair enough, but it’s easy enough to turn it on with no tube in it. Generally an open circuit won’t cause anything bad to happen, it just won’t work (electricity stops flowing). Either way, Schiit said it was fine.

I've asked this to Schiit support about removing a tube while the amp was one. They told me "Running it for any length of time without tubes won’t hurt it." It makes sense since a tube could easily burn out while the amplifier is running.

For the Valhalla you won't notice much (if any difference) from rolling the power tubes. You are really just looking at the two input tubes and those can be changed independently of the power tubes.

There are passive pre-amps that support output switching with volume control. JDS Labs makes one and I think there are a lot of generic ones from China on ebay. If you want to keep using the SYS and just add attenuation on the input to the Liquid Platinum, then you can get something like...

If you hook it up backwards then the volume pot needs to be maximum and you can only use it as a switch. If you want to use it to control volume it needs to be hooked up normal. You could try: Mimby -> SYS Output -> Sys Input 1 -> LYR -> Sys Input 2 -> Separate Volume...

If you want to use the SYS as a reverse switch (1 input, 2 outputs) then the volume pot should be turned all the way up. If you don't want to get a different pre-amp with independent source volume controls, then what would probably work best in your case is to get a set of RCA splitters to do...
