I have the lower end Kimber Select (all copper)ICs in my system, linking Plinius amp to pre and linking Oppo 95 to pre. Is it my ear that will tell if I jump to Analysis Plus Apex Silver, that this was a good spend to upgrade my musical experience?Considering that they and your bank balance are the only things that will be affected after their purchase, I would definitely say yes.
Thanks A
If they offer a more open window to the musical performance that you feel is commensurate with, or (if you are lucky) exceeds their cost buy them.
Try some alternatives before you make your final decision.
