Also have a listen to the TEAC UD-501 which also plays DSD and up to 32bit/384kHz using BurrBrown 1795 chips. No volume control preamp but there is a volume control for the headphone amp.
It's the cheapest DSD DAC by far.
Other well reviewed option is the Mytek (abt 500 bucks cheaper than the Benchmark DAC2)
