Synergistic Research SR30 Power Cables

    The Cable Company has a couple Synergistic PCs that will fit your budget.

     I'm still using a pair of SR AC Master Couplers (w/MPC mods from Michael Spallone).  One between the wall outlet and power conditioner.  The other between the wall and subwoofer amp.

                                 Haven't felt a need to upgrade in years.

So you’re thinking of buying the SR30 for every component in your system? Keep in mind, some power cords are better for DACs, some for preamps, some for amps. So this may not be the best plan. 

SR makes good stuff.

Enjoy.
