Wyred4sound dac1 would be a good choice, $995 new. More inputs than most DAcs in this price range, asyncronous USB.
I am currently using a PS audio Digital Link 3 with a M2Tech hiface USB/SPDIF converter which avoids need for a USB cable. As these items can be found used on AG and both could be bought for a total ~$550 it represents a great sonic value. Down side is that the PS DAc only has a single COax input so CD player would have to use the optical. This is also true for the Rega.
