For the money, if it is pure "technical" quality you are after then Benchmark DAC1 is hard to beat and has gained wide respect as an excellent DAC (jitter immune), a great preamp (but NO remote - so caveman design for modern times) and it comes with a world class headphone amp to boot. So no need for a preamp if you can handle the inconvenience of manual volume control or can accept the poorer performance of "digital volume control".
What sounds subjectively better will be a matter of personal taste - so I can't really help there. Benchamark has a tightly focussed soundstage that is generally narrower than anything else (great image between the speakers but less soundstage width/size overall unless it happens to be on the recording - if you like all your music to sound "big" then DAC1 is not for you)
