Looks like it's pretty costly. A model below it is around $3700.
Acrolink 8N-PC8100 Power Cable
This is just a short review of this absolutely wonderful power cable. I decided to post this in the Member Review section after owning this cable for nearly two years as the recent experience has left me amazed.
In brief summary, I find this cable to work very well with sources particularly DACs which are inherently transparent and detailed. The strength of the PC 8100 lies in the midbass and low bass. This cable truly brings out the midbass and low bass thus contributing to the added punch and dynamics in the music. It’s like adding a subwoofer or new amp to the system. No exaggeration here. Apart from the bass, instruments particularly in the upper frequencies sound airier, more liquid and 3-dimensional with a tube-like smoothness.
If you feel your system is lacking punch and weight in the bass, give this cable a try particularly on sources. If your source is already warm and lush sounding, this cable may not be a good fit as the sound will turn even warmer and thicker with reduced clarity and separation.
