I have recently upgraded the analog card of my DAC 4.1 (the one using the 5687 tubes) and this has largely improved the Dac.
Now I am going to work on the M2X power supply and I would like to know what are the parts that you would uograde (and the replacement) in order to make it even better ? (: capacitors ?, regulators ? Bridge ?)
