I am loving my DSD Mk1 with APS upgrades including Rev 1 transformers and outboard power supply to APS analog power supply board and VOCM upgrade . Although I am loving my dac I am curious about the improvements that the Signature dac upgrades would bring. It would be expensive for me considering the weak CND dollar against the US dollar. I do enjoy my current dac but I wonder what the Signature upgrades would bring. Any recommendations from others who have done the upgrades or not would be appreciated.
