Benchmark, X-Sabre, Anedio, W4S, and Yulong D8 are all solid options. I personally think the W4S DAC2 is one of the pieces of gear I wish I had, since I hear so much about it. I sold my X-Sabre since its a tad warm, and I like a brighter system, but its a great DAC too, and its DSD capable. I personally use a Music Fidelity M1DAC, and I love it. I also use a BH Crack with my T1's.
Your budget seams to be pretty substantial, so it might be worth it to try the W4S or X-Sabre.
As far as amps go, the Donald North Sonnett is a great match, as is the WA2. You could also go cheaper and do a Bottlehead Crack like I use. I also like the Burson Soloist. The Eddie Current Super 7 would be good too, but probably not as good as the others. Depending on what you like the looks of more, what other headphones you plan to use, and what the rolling you plan on doing, you may want either the sonnett, WA2, or maybe a Decware amp.
