Where to put your best

If you are using a power conditioner your best power cord must feed it.
Next comes your CPD (or transport followed by your Dac.) Preamp then amp.
Basses upon testing I've done with my tube and SS systems this provides the best resolution and bass slam to me.
Of course everything is system dependent and it also might depend upon your power filtration system that you have in place.

A week ago I moved my "best" from the preamp to the PLC. It had been on the preamp for about two years. Much better on the PLC.

Thanks to everyone for your help.
Again Thanks
