Lyr 2 Ting Noise with Chassis, Switches

post #1 of 8
Thread Starter 

Hello,

 
I just purchased a Lyr 2 amp with the USB and uber upgrade. There is a strange behavior happening on the amp. It is hooked up to a Bifrost DAC. I have tested both Optical and USB Windows and OS X and the behavior is the same.
 
Whenever I touch, snip flip any of the switches a ting sound comes into my headphones. I also get this if I snip the chassis, the cable moves and now when I move my mouse. It seems any reverberation that gets to the chassis results in the headphone speakers making this annoying ting. I put my PSBs headphone speakers right on my MIC and recorded it while tapping the chassis and snipping the gain/power switch. You can hear a light bell like noise. This didn't happen on the Asgard 2. Keep on mind this is MICd up good. Im just tapping the chassis where it sounds like I'm beating the schiit out of it.

I get the same sort of noise out of my Lyr only if I give the chasis a hard thump with my finger, light tapping isnt audible (maybe because i'm using planars?). have you emailed Schiit about it?

Hi,

 

I did email them and received a response this morning. They state it's normal for a tube amp. I can't consider this normal but I don't have any exp in tube amps. But any movement I make that moves the wire, or resonates vibration on my desk results in that ting noise. I can't enjoy any music with this thing.

 

EDIT. They're going to send me some new tubes. Good service. Hope it gets sorted.

Good luck with your new tubes, actually just recently in the last two days my left channel tube has started making a ting every 30-60 seconds which is kind of annoying.. might have to roll some new tubes.

Thanks!

 

For me it happens all the time. I don't know much about rolling lyr tubes. I guess there's a thread on it somewhere. Have you researched that much yet? I wouldn't be opposed to getting some tubes that are trusted and perhaps "warm" sounding.

Well I received a second set of tubes from Schiit. It didn't help very much. I had to return the unit. Maybe others had a better experience than I did. I really wish I had a good unit. Regardless I think I'll stick with their solid state amps. I love those.

That's bad luck :(

 

I received my new set of tubes the other day along with some socket savers and my ting issue is now a non-issue thankfully.

Good luck with your new amp.
