This OCXO is bringing the LKS004 into another tier of class with my Pinkfaun I2S. The soundstage is now much more vertical (which was never impressive to me from the beginning, but now it is! And this thing isn’t even done burn-in). This soundstage and the deeper more dynamic timbres (more depth, and hence more organic) are all very obvious improvements, together with other details. I can totally see where Pulsar will play a huge role.
To those people who doesn’t have this powerful regulators, may as well save the money and wait for Pulsar 100Mhz. It will be a simpler job of removing 575 crystek and put in a DIL-14 dip sockets, and then dip-in the Pulsar.
Other clocks is also an upgrade such as 575X and 950X, they are the next sane tier of improvements for many other LKS004. The lks004 is already built with so much quality components. They even leave out the holes to fit in the DIP socket ! This is the reason why clock can be so important and show so much improvements
