Shunyata PC's - Taipan/Python Helix

Hello,

Do users of either the Shunyata Taipan/Python Helix PC's from the wall through a Hydra 8 find that using these cords tends to lower the output level of music being played?

I am testing both these cords and found that I have to play anywhere from 3 to 10 db higher to get the sound up when using a different PC (all other items remaining the same) and with the same track/disc...

Both these cords snap the music into focus and smoothens out the sound versus my DIY Furutech PC (with Furutech gold receptacles)....The difference is really quite remarkable.

The Taipan is good but the Python really gives a fuller body to the music....but as I observed, tends to lower the sound level...

Between the two, the Python does a better job, widens the soundstage and makes it nice...and easy to listen to..no fatique....

I do note a little veiling (could be a little more transparent) of the music but this could be due to my 13 year old JVC source being the cause or the Shunyata cable characteristics.....I am in the process of looking for a new source...

My other question is whether the Virtual Dynamics Nite II/Master series or Black Sand Violet/Silver Reference are in the same league of the Shunyatas? I am considering these cables...

I listen to Jazz Vocals, Vocals, LAtin, World music and pop...

WOuld appreciate your comments before I take the plunge...

Thanks....
