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.

This is a very informative website and the forum community is very good and helpful. Thank you all for your suggestions!
I had the Rega DAC. Very nice and well within your budget. I upgraded to the PS Audio PWD MKII which is much nicer but out of yor budget range. Look on AGon for one used. You would be giving him a great DAC for half your budget.

For $2000 exactly, the NAD M51, which compares favorably to the Anedio D2 and PS Audio PWD MK2.

It's selling very well though, so may also be hard to find. Crutchfield (the Internet based audio dealer) may have it in stock, or even better, your local dealer.
If there was a way to stretch the budget just a bit you could get a PS Audio perfect wave DAC mk II. I've seen new ones for sale with the sound bridge for 2700 right here on audiogon. This DAC is supposed to compete with DACs at any price and it sounds excellent run directly to the amp and using it to control the volume.
