I'd suggest anyone with I2S capable dac to procure a ddc or I2S capable streamer with OXCO clock, slave/sync this clock to dac. You will get greater resolution/transparency and possibly even more important a much more analog like presentation vs any present input being used. Greater resolution/transparency due to I2S being the native signal path within dacs, dac no longer has to convert other schemes to I2S, also doesn't have to extract data from clock. More analog like presentation due to superior OXCO clocking. Over the many years I've been streaming have tried various clocking schemes, this via usb,with more precise clocking heard direct correlation to a less digital presentation, the long known effects of jitter became manifest. Move on to I2S via Denafrips Gaia with it's OXCO clock, immediately and easily heard presentation that flows much like my pretty nice vinyl setup, far superior to clocking improvements via usb.
Bottom line, for this decades long, somewhat jaded audiophile, the conversion to I2S rates in the very top tier of upgrades, very meaningful.
