A lot of high tech/high end DACs are listed here for your consideration. But, in addition to these technologically-advanced models, you should hear something like the ultra primitive Audio Note DACs. These things use some very old chips and have spectacularly poor measured performance. And yet, to my ears anyway, they deliver the goods in terms of a natural, harmonically dense and musical sound. The top models are crazy expensive, but their lower priced models, while not cheap, deliver most of the goods of the top models (all of their DACs have similar digital circuitry, it is in the analogue stage that the high priced models utilize much better parts),
The Audio Note stuff delivers a different sound. You may prefer it or you may not, but, it is worth exploring because it is quite different.
