Choosing between the following three cable brands


Following many great comments and discussions with fellow inmates and manufacturers... I've shortlist down to the following for my system.
1. PureNote Paragon i/c and spr cable
2. Gurreilla Sivlver Push/pull spkr cable
3. Cerious Technology i/c and spkr cable

system:
MBL 1531 CDP
I/C: Harmonix HS101GP 1.5mm XLR
P/C: Gutwire PowerClef SQ going into PS Audio P500

ARC Reference 3 Preamp
I/C: Harmonix HS101GP 1.0mm XLR
P/C: VH Audio Airsine going into PS Audio P500

Krell FBP 200 C
internal P/C to wall

Speakers: Verity Audio Fidelio Encore
S/C: Harmonix HS101 2.5mm single wire

PS Audio P500 PowerPlant with Labcable into wall.

Music: Bocelli, Pavarotti, Sarach Brightman, Secret Garden, YOYO Ma and general violin concerto.

Lacking: speed + dynamics, Cello doesn't dive deep on base at all.

IMHO,
Your Harmonix interconnects and speaker cables are going to be damn hard to beat.
My guess is if your not happy with the sound it's not your cables, most likely your room needs some work, or perhaps a weakness in a piece of equipment however I have no idea where the weakness would be, it looks very good to me.
Of the cabling you mention, the only one that *might* better the Harmonix would be the CT!
Do you use dedicated circuits and high quality AC outlets?
I just returned the CT cables after a 12 day audition. I much preferred my HMS Gran Finale ICs and my DIY solid silver/teflon/cotton speaker cables.

I have been strongly considering Valhalla speaker cables, but the leaness that some describe has made me hesitant. I am currently burning in Pure Note Paragon speaker cables with power resistors. We shall see.

I also recently installed my 4th EG cord in my system - an Epiphany on my Berning ZH270. I still don't get how power cords can alter the sound so much, but this cord is staggeringly good.
Consider Crystal Cable.
Harmonix are lovely but in some systems can tend to favour a round sound with full mids - warm and a bit soft at the extremes. I know of several people who found Crystal a good alternative.
FWIW
