Ptss: That is a very good question. I will let you know in early February after I start using the Ayre QB-9 DAC.
I heard the Ayre QB-9 using the MAC Computer, my amplifier and my speakers at the Audio Store and liked it very much. I am currently using the MAC connected to the DAC in the Oppo 105 now and it does sound very good. I felt the Ayre QB-9 sounded better but the real test will be when I hook up the Ayre and compare it to the Oppo 105 in my system.
