I built my own power supply for the DLC and the improvement was very significant. The power station 1 is way below what is required for any competent preamp. By the way the same applies to the MSB DAC.
It is going back a few years so it is hard to be specific. Not being a wizz with electronics I stuck to a standard design and decent materials. Good as the DLC is, I don't think it warrants anything more than the following. The transformer was 150 VA potted toroidal I think, but may have been bigger. However I used one that was lying around and otherwise would have been happy to buy a 80VA one for this application. I cannot recall what rectifier diodes I used, they were supplied by a local chap who said they would be best for the application...? The first filter caps were Nichicon Muse - I think about 5,000uF a side (but high is good). I used an LM317 and an LM337 for rectification, dropping the voltage about 10VDC (to about 16VDC is it - I cannot recall). Final filter caps were Black Gates, I think about 1,000uF a side (too high a value here can degrade things from my experience). I find there is no improvement in bypassing Black Gates with small polyprops and so did not in this case.
