@Black_Hawk as far as I understand, you are looking for bluetooth receiver for casual listening from Tab or Phones and for playing high resolution lossless files, you already have a PC and DAC (KTB). The options from Ifi or Auris suggested by our FMs are very good with descent DAC, but for casual use you can get any cheaper options from amazon and you will not feel much difference for playing lossy mp3s or from youtube etc. I know there are guys still using old Logitech bluetooth receiver, they are not even on latest bluetooth version.
Btw, what you mentioned in the post is a bluetooth transmitter not receiver.. but you need a bluetooth receiver only.
