      Annoying earth hum issue using USB

      By darth vader · Posted

      I'm getting an annoying earth hum (or at leat thats what I think it is going by the sound) using USB hook up between my fruit computer (2014 imac) and a Line Magnetic DAC.   The background is I have been using a 5m optical connection with no issues. A friend visited with his laptop with some fancy software. After loading the DAC driver we had a bit of listening and discussion on the merits of optical and USB. I've been wanting to try USB for some time. I had tried it before but had difficulties overcoming getting signal out of fruit computer via USB. After much googling I finally got it worked out. I managed to scrounge up an extension USB cord, and thought I was in business. I could now finally enjoy the rumoured improvements over optical.   But alas, I couldn't resolve the hum that I was getting.  I disconnected all other USB devices, save the drive where my music files are...no change. I moved the computer to a point where I could eliminate the USB extension and use the same USB cable that was working fine a few hrs before on Martys laptop...again, no change     So, I'm at a bit of a loss for things to try. Apart from jerry rigging some kind of earth lead from the DAC to the PC, I can't think of anything. Besides, I've never seen nor heard of that ever being a fix. Even if it was a fix, I dont think I'd like to have to live with that. Just not the right thing it feels.    Anybody got any idea what might be the cause and possibly a remedy?

      Hey Cam, I didn't know you had those speakers. I didn't know I could hear them anywhere in Australia. I'd love to have a listen next time I'm in Sydney (hopefully before Christmas) if you don't mind.

      Dueland tinned cable - input requested

      By MattyW · Posted

      I just replaced the cheapy oxygen free wire I got from Bunnings that I was using in my downstairs system with vintage Weston Electric 11GA tin plated, cloth covered, oil impregnated wire.   My God, what a difference.  A palpable increase in Bass, smooth and laid back. More punch, layered etc. This is just what this system needed. Well worth the time and effort,  and quite cheap as far as audio upgrades go.    The difference is larger and more pronounced than going to the Dueland wire upstairs,  though I was already running decent wires there. Likewise this is a single run of wire from amp to the Dayton USA PS220-8 full range drivers in the cabinets with just the locking banana plugs in between. This might have overtaken my main system again
