I couldn't find anything on here so thought I would ask. I bought a used little dot mk III on ebay that is supposed to be good. It arrived in good condition but when you get to where the cans starts to get a decent volume they distort badly which is over 70 percent volume. I know this amp is supposed to drive better than that. Could it be the driver tubes are worn out? They sound is good under 70 percent volume.I tried with dt770 15 ohm and m50x as well as shure 440's all the same results. This is my second tube amp but the first is aune which only has 1 tube.
