drag me into the digital age!!

evening Goners,

My children gifted me an early set of Christmas presents that include an Auralic Aires streamer(?), a Holo Audio Kitsune Edition Dac(?/), a Holo Audio digital to digital converter(???) and a stack of digital xlr,hdmi and USB cables....

Of course, being my kids, the last two months have gone by without either one setting this up to run with my Gamut amp and preamp and my Bryston headphone amp!!
My CD player is a Rega Isis that has a USB"out"...
Since I am duty bound not to let this sit any longer I would be EXTREMELY grateful from any Digitophiles out there!

Thanks,
