@izgmoen I don't honestly understand exactly how these clocks work. I bought the Gustard U18 and LHY ock-2 to use with my Gustard R26 dac. I had a SMSL VMV D1SE before it.
The LHY has three sine wave outputs and three square wave outputs. I use one output to my X-30 and one to the U18. Everything I had read said to use the sine wave output, so I did. @lanx0003 asked if I had tried the square wave outputs. I gave it a try and there was a noticeable improvement in sound quality.
