I auditioned two DACs with my Bluesound Node 2. The Border Patrol DAC and the Mhdt Labs Orchid, Both presented a marked improvement over the onboard DAC in the Bluesound, After a couple days of A/B listening I gravitated to and purchased the Border Patrol. To my ears it has a more enveloping and analog sonic quality, closer to vinyl which I listen to around 90% of the time. No idea how it would compare to a DAC costing two to three times more, but it works very well in my system. I like the Bluesound interface and since it supports Tidal I find I am all set...at least for a while.
