I've added a sound card and it has reduced the noise a large amount. When I'm not opening a program or scrolling there is no noise and if the amp is on about 60% volume you can hardly hear anything. I keep my tube amp on full volume to get better sound and adjust through my DAC. Because of the...

Will something like this for optical to my DAC solve the problem...

It's not really a buzz. It's just activity from within my computer. Opening programs, scrolling mouse wheel etc. Will I get this issue with all amps or all tube amps or just this specific LD MK2 tube amp. I'm too busy and too poor to solve this issue. If the issue lies with noise from my hard...

When I unplug my HDD, my computer does not start as it says that it is the boot device even though my OS is installed on my SSD which isn't very big. The crackling noise does seem to occur when the LED flashes. Will using an optical output get around this because I can't really just get rid of...

Yes I think you've hit the nail on the head. My PC does use HDD - should I just turn off my PC and unplug the HDD and just use with my SSD? I don't have optical fibre output on my PC - my dac does have optical input.Should I buy a soundcard to get optical output?

No I'm afraid it doesn't

I have put it on a completely different set of outlets. I don't think it lies with wifi signals as other things unrelated cause noise - any activity on computer. I don't have any tubes I could roll but I'm not sure that would help. The noise sounds like it's coming from my motherboard circuitry...

Hi thank you for the help, I don't think it is a ground loop hum now after some trouble shooting as the noise is related to what I do on my PC and increases as I change the amplifier volume. I run windows 10. It may be to do with running my DAC through USB although I hear none of these noises...

I still get the noise with the LD MKII plugged straight into the PC. I don't have optical option. I'm pretty sure even non shielded cables wouldn't pick up computer noise outside of the computer a metre away. I think it's something to do with a ground loop issue which I don't really...

Good idea but I've done that and I'm still getting noise - related to what I'm doing on my PC

Hiya, I have been using this website for a while but never thought to make an account. I have found some help on this issue but I need it in some more simple terms as I am quite a newbie. My setup is my PC connected by USB (which also powers) my Audioengine D1 DAC (which has a small built in...
