I originally used the Master Clock setting and thought the results were very nice with an Esoteric 75ohm cable. I switched to the 10MHz out with the same 75 ohm cable and was blown away by how much more dynamic the sound was. At first, I thought it raised the noise floor but realized the opposite happened and I was just noticing sounds in the recording I never noticed before. As mentioned earlier, I'm also playing a little louder than normal using this setting. The hunt is on for one of the elusive Esoteric 50ohm cables because I'm sticking with the 10MHz out for now.
