Just entered the world of high resolution audio

I dipped my toes by obtaining the HD Tracks free samples. Now I am ready to get something else- I'm into jazz so can someone recommend some music that is both excellent music and sounds great. I already have Kind of Blue on CD and vinyl, so I'm not really interested in Kind of Blue in yet a 3rd format 

Check out the digital only label Sound Liaison. Mostly live recordings in front of small audiences, direct to hirez. Amazing stuff. Carmen Gomes is marvy, as is Paul Berner Band. 
Try the new album "Undercurrent" from Sarah Jarosz.  Wonderful musician and great sounding album.  It is on sale at ProStudioMasters right now in 96/24.  They've labeled it as "country."  It isn't so don't let that turn you off.
