YES! SOUNDS COMES OUT! WOOHOO! PRAISE THE LORD!   One of the tubes fell on the side though and that channel stopped. I wonder why I have so much trouble to set these in place correctly. Maybe I should ask my audiophile friend to help me.

Yeah, that's why I deleted the pictures, I did something incredibly dumb. LOL It wasn't like that the first few times, it was afterward when I linked an audio source to it.

Good news, it looks like I've spoken too soon, I seem to have gotten the tubes to work now:       However, sadly, it hasn't solved my issue. I plug the USB cable of the Bitfrost into my PC (I made sure to get a certified USB 2.0 cable), it is recognized as a Bitfrost DAC and selected...

  That's how I tried to insert them.   Here is a picture of how it looks like, I turn the lights off:       I tried switching the tubes. I know that no matter what I do, only the tube placed in that spot lits up (doesn't matter which of the two tubes it is).

All those I have checked (except for 5 which doesn't apply).

  I am pressing quite firmly, but it seems they're still quite unstable after. They don't seem to lit up, except one which seems to lit up just a little bit. You're saying I should press even stronger? At this point I'm a bit afraid of damaging something.   I plugged a stereo source into the...

Hello it appears the Lyr2 I bought (in conjunction with the Bitfrost) is not working, it emits no sound when used with just the amp. I hear no sound in the headphones at all, other than intermittent hissing, and a popping sound in the headphones when closing it.   I'm starting to regret having...

  You appear to be right, a source from the Lyr directly gives me the same result. No sound, except for sporadic hissing.   I don't understand because I tried to follow the instructions.   What else can I do?

I just received my Bitfrost with the latest upgrades, along with the Lyr 2. I was excited but no sound comes out of it at all.   When I try to install the USB drivers it tells me "please connect device" repeatedly and then terminates because it says it cannot find the device. However when I...

  I have a very basic and inexpensive one, the Fiio Andes E07K. I just wanted something simple to begin that would work with my portable, and invest in something more expensive when I have more spare money.   I was just wondering if something like the Benchmark would be worth it for me to get...

What DAC/amp do you guys use with the Primes? Someone I know is trying to convince me to invest in a Benchmark DAC2 HCG, is it worth it or overkill? I'm not sure most of the music sources I will listen to will always be of very high quality.   Definitely lovely sound so far.
