I have a variety if systems with DACs. My base system is a Denefrips Ares II. it is a really good basic dac. My mid system has a FIIO K9 Pro ESS. it is a dac and streamer. it has two ESS 9038PRO dac chips and costs less than $1k. Absolute bargain of the century. My high end system has a Cary Audio DMS-700. It is good, not great and definitely not worth the high $8k price tag.
I also had a RME Adi-2 and a Schiit Bifrost, which I didn't like. Sold them.
I really think the FIIO sounds fantastic. Especially for the money.
