Thanks Peayel. I do intend to upgrade my DAC and amplifier at some stage. Having so little Hi Res music, and it can't be streamed from iTunes through the ATV anyway, I have no opinion at all about whether or not it is better that CD quality, but I would rather keep my options open, especially if other items are going to upgraded.
"Inspired" Manticore Mantra TT, Technics SL-7 TT, Slee Reflex M phono preamp. Cyrus CD Xt Sig. iMac, Raspberry Pi c/w HiFiBerry Digi c/w MoOde, Slee Majestic DAC. Roksan Kandy LIII amp, Spendor A5 speakers.
