I can't speak to the Transparent PC, but I did not like the JPS digital cable. The filtering became a choke point, limiting dynamics and imaging. Use a power conditioner or isolation transformer if you want to clean incoming power, cables should provide an unrestricted current-draw.
Power cable upgrade or sideways move?
I recently changed my interconnects and speaker cables to Transparent Super Gen 5, and I am really enjoying the results. I’m thinking of switching over my power cables to Transparent as well. I’m currently using an original JPS Labs Power AC on my Levinson ML 383, and original JPS Labs Digital AC on my Krell cd player. I’ve read that both the ML and Krell have AC filtering within their power sections and that using power cables with additional filtering may provide less than favorable results. With that in mind, I was thinking of going with the Transparent High Performance Power Cord as there is no AC filtering network. Do you think going from my current JPS Labs power cables to the Transparent High Performance power cables would be an improvement or sideways move?
