I would look other than Esoteric for Redbook only...
Esoteric K07X versus K05
Strictly for redbook CD listening to classic rock music, second hand sale. Which would you steer me towards?
I'm currently using a Plinius Hautonga integrated, Rega RP6 + Hana SH, Naim CD5X into Totem Sttafs in a dedicated two-channel listening room.
No interest in using the Esoteric as a dedicated DAC for streaming.
