Long-time Mc owner and fan here. @jastralfu and @fatdaddy2 are entirely correct. Any McIntosh product that doesn't have both perfect cosmetics and function can only depreciate until such time as it becomes a "classic," whatever you interpret that to mean. Even then, you would face a hard time reselling the item and a lot of blowback from potential buyers. Mc commands the second-hand market value it does because if you take care of it, it will last a lifetime looking just the way it did the day it came out of the box. Anyone who lets the cosmetics go doesn't understand the value proposition McIntosh is built on. Keep looking.
Others are also correct about the DAC. Don't get hung up on that. The DA1 works just fine and the DA2 is a modest improvement on it. If you get a unit with either and don't care for it, getting a stand-alone is neither difficult nor expensive. Don't let that come between you and the music.
Good luck with your search and happy listening!
