I have the first Lyr, and I usually listen to it at about 11, but I will take it to near 12 when I want to be really engaged.
NEW Schiit Lyr 2: Impressions
I have the first Lyr, and I usually listen to it at about 11, but I will take it to near 12 when I want to be really engaged.
I had a similar problem with the original Lyr. I swapped tubes and it made no difference. Schiit graciously told me to send it back and they would ship me a new one. The new one did not have the problem. It was a hassle-free return and great service from Schiit.

My Schiit Lyr2 arrived today, customs in my country are EVIL. I paid about 500 dollars for the customs alone, and not including the taxes\delivery...
haven't had the time to listen to it properly yet. but I tried it with my Hifiman HE4 and Beyer T1 with good condition- Siemens Pcc189 tubes, There's a horrible hum when turning the volume knob to listenable levels(11-12 oclock) like the kind of hum you get when you try to max the volume all the way... I switched to the stock tubes and the hum decreased.. but still itis way too much hum in 11-12 oclock with those headphones(the gain switch is set to high, low gain just can't power those headphones well) it overshadows the whole music and I can't enjoy it that way.. there is no background noise\hum when the music is off though.
When I have more time this week I will investigate it further and see if I can fix it easily.. I don't want to send it back to Schiit because it will cost me a lot..

Hum can be caused by ground loop. Try to use Schiit power cord with so called cheater plug.

Good luck. My Lyr 1 sounds great, but has a hum. The extraordinary hum that it developed one day must have been related to a tube, or the seating of the socket savers/tubes or something. At present, it is bearable. Yes, I have tried the JK Audio Purifier - two of them, in fact!

Commiserations about the terrible charges - I thought that it was bad enough in the U.K, but that is something else!

so, from a few fellow owners and some Lyr 1 threads, it seems that the background hum/hiss/noise is typical of Lyr amps, both gen 1 and 2, so I should just accept it as it is?
when I use my Lyr2 with HE500 the knob is at 12 or 1 o'clock position.

1. my Lyr 2 is dead silent. with no music playing, volume knob max cranked on high gain. black and quiet.
even with my NAD HP50 plugged in which are somewhat sensitive.
I don't believe you should accept the hiss, but can't assist with what would fix it in your case.
my Lyr 2 is plugged into a Furman AC215-A.
rest of path is: iMac-->Wireworld Starlight USB-->Concero HD-->PYST RCA cable-->JK Audio Pureformer-->Wireworld Solstice RCA-->Lyr 2
2. Lyr 2 on high gain with my HE-560, volume knob between 10-12 oclock.
low gain (which I don't recommend with HE-560) can crank it up to 2-3 oclock, which is loud- but sound is thinner and not as full bodied.
Lyr 2 with Ediswan tubes has me shaking my head nightly in amazement of the realistic, live sound of even "average mastered" recordings (lossless 16/44 rips).
sweet.

+1, I am able to hook up my Lyr 2, with SONY XBA-4's and PSB M4U's with dead silence, even with the volume cranked, in low and high gain without music playing. I would check my tubes, how they are seated, all connections, disconnect the amp from all inputs and see if the hum persists, if so use a cheater, if not, check your sources. I use a Monster Power Station, strip, not expensive and prevents ground loop or bed electrical system hash, can you get something like it in your locale? If this doesn't help, contact Nick at tech@schiit.com, he's great at responding in a timely manner. Best of luck, cheers!

Lyr2 pairs well with AKG Q701.
I'll be using the Lyr 2 with the TH900, and I'm trying to keep them sounding fun and fast, while filling in the midrange. It sounds like the
Tungsram 6922 (http://www.upscaleaudio.com/tungsram-6922/) and the Telefunken 7dj8 ( http://www.upscaleaudio.com/telefunken-pcc88-7dj8/ ; I can't afford the 6922
) might do the trick. Anyone have experience with these tubes in the Lyr 2, or even in combo with the TH900? Any suggestions on other tubes to consider ( less than 150 for the pair)?

I do not know the TH900. Are they slightly more bassy and dark? If so, I would suggest the Amperex Orange Globes. I pair them with my HD650s with wonderful results. If they are a bit bright, look at the Bugle Boys (1959 is the magic year). I have found that Vokshod Rockets 6n23p, which is cheaper than both of these, does quite well with both of my cans. I absolutely love them.
