Audioparts Inc has one for auction here in the power cord section. Can't speak to the unit nor the seller but its another choice. Chris Hoff @ BPT also makes one that received a good review (if those things make any difference to you). It comes with or without filtering, etc. and can be found in the "AC" listings here @ A-gon. Blue Circle Audio also makes one as does Gutwire but I don't know if their respective units have "filtering" or not nor am I aware of their prices.
No nonsense Power Strip
I have and old home and unfortunately I am limited to one outlet. I need a non-current limiting, non-filtering, non-conditioning power strip with no sonic signature. Can you help?
