PrimaLuna One, interconnects,cables,power chords


Has anyone experimented with interconnects,speaker cables, or power chords? I am thinking about upgrading from Audioquest King Cobras, and very inexpensive speaker cables, but I'm not sure if I should consider silver, or stick with copper.Maybe Zen's, or Analysis Plus.
I'm trying to get a bit more sparkle and transparency.
I presently have a Theta Miles CD player(which is good for taming the bass), Spendor 3/5se speakers.
Will changing tubes help?
Thanks for your help.

Nordost Blue Heaven interconnects and speaker cable, and D.H. Labs power cable. Check the used/demo list at Upscale Audio for a good deal on Nordost Blue Heaven speaker bi-wires (last time I looked.)
I have a hard time justifying spending a lot of money on cable, PC and I/C just to improve this amp's "sparkle and transparency" (not that you need my justification). One of its biggest attractions for me is it's price/performance ratio. What I would do is some tube rolling. You can change the sound of this amp quite a bit by changing the small tube's and power tubes. You can play with new production tubes on the cheap or NOS. Call Kevin Deal and discuss w/him your what you want to do and see what tubes he would recommend. I would agree that changing your speaker cable to Nordost might help the high end, I'm just not sure how it will effect the bass.
Could someone explain what NOS tubes are. I assume they are re-conditioned or something. I just am not sure what this means.
