Speaker cable suggestion

Well if you are looking for neutral and transparent, the Nordost cables are about as far as you can go in that direction, so you should enjoy them.
I think the Stealth Hybrid MLT are one of the best buys in cables at their used prices. Almost as fast and transparent as the Nordost, but with a slight hint of sweetness.
The AZ SS are more full bodied and natural sounding, a different type of sound all together. I would not call the AZ sound neutral or transparent. So it all depends in what you are looking for.

One word of warning: I have found that, like most cable companies, Nordost sound can be cumulative. I have often enjoyed a little Nordost in my system, however, I've twice tried going all Nordost and neither time did I like the final sound. Instead of fast and exciting, articulate sound, I started noticing the lack of musical weight and listening fatigue started to become a bigger issue. As always, YMMV.

Hi Jmcgrogan2, thank you for the info. It's very useful. At the moment, I would say my system has quite good musical weight (esp. after I "somewhat" addressed my power distribution with PS Audio products - dectet, power port premier receptacle and ac-12 power cord). My ICs are Heimdalls (both XLR and RCA) and my speaker cables are one of sc mentioned above (I will leave out the name). My speakers are Focal Electra 1028Be and amps are all Pass. I feel I have open, smooth and "meaty" (for lack of a better word) sound. The area I'd like to improve is the mid-bass naturalness and speed.
The reason I know it's the speaker cables is because I also have cheapo Tributaries 12 gauge sc. Switching this in and out with the current sc, the mid-bass problem is gone (speed is still the same) despite all the other shortcomings with the Tributaries.

Well it sounds as if the Nordost is what you are looking for then. Happy hunting!!

I ordered a pair of Nordost Frey series 1. They should arrive by Friday. :)

if Nordost Frey you are not satisfied ,you can try Anti Cable reference, it's really really good speaker cables and now i'm use.
i use Stealth MLT cable before,it's really really good speaker cable,very balance.and bass is tight,detail,deep and bottem end,but bass amount is not enough for my sstem,so if your system have too many bass amount,Stealth MLT is right choice.
