Joseph Chow from Audio Horizons power cords. Very neutral, and just the most natural sounding cord. So I screwed it up and added Oyaide plugs, this has been a huge improvement, along with his amazing Dimension interconnect. This interconnect beat out the Acoustic Zen Silver Matrix for my cd player to pre-amp. I could not get Joseph to sell me another dimension interconnect as they are still in design stage....but WOW!! I kept the Zen Matrix Reference ll for the amp/pre-amp connection. Also my AR Classic 30 loudspeakers, I still love my BAT cd player, but I would buy Joseph's tube DAC in a second!
