Looking for DAC suggestions


I am looking for a good DAC for my boyfriend. He has a Mcintosh 275 amp and he is now looking to buy a DAC( the one he was looking into was Anedio D2, which is currently out of stock). I want to buy him a DAC under $2000 for his birthday and I dont have any idea about DAC's and which one is good. Can someone suggest a good DAC which will work well with his Mcintosh 275 amp.

I agree with Phaelon. Think about giving him a card saying that his birthday present is any dac of his choice, 2k or less. Explain to him that you want to buy him the exact dac he wants. When someone is as hardcore about a hobby as it sounds he is, it's usually best to let them make their own decision. By the way, he should propose to you... like yesterday.
Whole heartedly agree with both Phaelon and B_limo. You can't go wrong with a card, and you almost can't go right buying him a DAC for reasons stated above. You Da Bomb.
Thank you soo much for your suggestions. I decided to go with the card approach - I think it will work out best that way since he is pretty picky about his music setup. I want to thank you all for all the inputs - I have learnt quite a bit about DACs in this process :-)
Phaelon got it spot on. If someone bought me a DAC, I would actually be pissed. Your heart is in the right place, but I STRONGLY advise against this.
