Disclosure: I rep for both of these DACs, but I chose to do so because of their performance and actually make very little money on sales
I third the MHDT suggestion, they sound perfect, and the Border Patrol DAC is also a great one.
Some really good deals on Wavelength DACs going around right now as well, and I highly recommend them (I don't sell them). I had a Brick for a long time that I would still have if I didn't need more input options.
Regarding DSD and MQA . . . just get a good recording and immerse yourself. If I have to listen to someone ask what file type is playing before they actually listen to the music, I will probably just grimace internally, but I'll want to scream.
