After looking at your system and seeing your goals, (clarity and soundstage)my advice is to forget the dac, scrap the PS power conditioner and pick up a good power conditioner, such as an Audience AR6, or the 6T if you can stretch. Lower noise floor and overall sound improvement, IMO. Of course I can't diagnose your system without hearing it, but neither can anyone else, so my opinion is as valid/ignorant as anyone else's. Again, IMO, a $1000 DAC is just a sideways move. If you want a real improvement over the AA, you will have to break more eggs than that. At least that's what I've found. Good luck.
Would adding a Dac improve the sound for my setup?
My system consists of Cary sli80 and audio aero prima mkII cd player. It is older model with the cd tray on the left. I'm looking for a Dac in $1000 range, like Burson Audio, MDHT Havana, TDAC or Rega Dac. My question is by adding one of this Dac does it improve the sound or simply moving sideway?
