You may want to look for a Sony HARD1000. It has a digital out so you can hook it up to your existing DAC if you have one.
I think this is discontinued, but you may be able to find a used one. Audio Consultants in Chicago used to have one for around $200 used, but I don't see it on their website anymore. I almost bought this myself since I was going down the same path as you are.
