Speaker cable suggestion

I've been waiting for Heimdall (8' length and banana) to be available on A'gon for quite some time but mostly Frey's come up quite often. I use Heimdall ICs.

Thank you all for the suggestions. I think I will give a good look at at AZ SS. How about Synergistic Research Tesla Accelerator? I've heard a lot of good things about SR and even with Tesla now, I think, discontinued, it might be worthwhile to try it out.

What about Frey? It seems, for a little over $1k, I should be able to get a pair. I'd think the synergy with the Heimdall ICs should be good. How would Frey stack up against Stealth Hybrid MLT, AZ SS, etc?
I currently have one of the sc mentioned above pairing with the Heimdalls and am trying to be very careful with system matching. I'm not one for trying out a lot of cables.

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.

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