I'll second the audition of RWA recommendation.
Own both Consonance Droplet 5.0 and Isabellina DAC (build-in my Isabella pre) for a while now.
RWA DAC is more then competitive in comparison. aa
Isabella pre with DAC option is one of those products which fulfill my cravings and search for excellent digital reproduction and preamp section. With selected chip, SET and PP amps, I am also set with amplification for my personal needs. Speakers are the last piece of the puzzle but that seems to be solved by custom SD speakers that I am building.

There are probably other great DACs out there, so take your time and see what fits your preferences and budget.
And do not forget that it is all in the synergy and there is no "ONE" best, fits all product which will guaranty you the desire performance.
Vinnie offeres - free in home 30 days audition
You should at least take advantage of this offer and if it is not what you're looking for - simply return it.
Good luck
