Greg, the digital to analog conversion is done with an intergrated circuit. Digital goes into the chip and an analog signal comes out. It is all done inside the chip.
digital signal in ------ chip -------- analog output
You can add tubes at that point but the conversion is done.
Mr. Tennis, why are you looking for a player that is as close as posssible to the Audio Note? If you revere this player and need another one just buy another Audio Note. If you are as thrilled as you seem to be and only hope to come close to it's performance why would you want to replace it? This looks like yet another Mr. Tennis troll.
