Advice on speaker cables.

@kmm84 good for you to try things out for yourself.  I noticed a significant improvement from power cables personally.  If you ever want to dabble in cabling that isn't exorbitant, I have had great success with Cardas Parsec power cables on my amps and front end components.  They fleshed out the sound more than a stock cable and I preferred them over much more expensive cables for their more natural and fluid presentation in my system.  Can find bargains for used ones.  There are never many on the used market. I gather this is because the owners have been quite happy with them. 

Then the other component that helped a ton was Shunyata power conditioning.  Can find used MPC-12 for bargains (got mine for $650).  I think proper power is so key.  If you get a chance to borrow any Shunyata gear I think you'd be surprised.  I use a Shunyata Theta 20 amp power cable for both my Shunyata conditioners with amazing results.  Each component matters in a good system!  Best of luck to you and keep us posted on your experience with your Hero interconnects.  Curious myself if you hear anything

@jrareform does your power conditioner provide surge protection as well? I’m just using an Isobar Ultra for surge protection. I know unplugging during a storm is the best but not always an option in the summer. On my old home theater setup I’ve had a Monster HTS something and it’s always done okay. I’m not sure if using the Isobar degrades anything. Any advice on reasonable surge/conditioner?

@kmm84 good to hear. Same drill with the Hero interconnects - give them time. Just use the system and the cables will settle. 

@kmm84 yes the shunyatas provide robust power surge protection as well.  I also have been meaning to do a whole home surge protector as other audiophiles have recommended to be double safe with my gear.  The Shunyata power conditioner probably made the biggest difference of any tweak I made.  I don't think our power is terrible but we do have an electrical box behind our house that causes issues sometimes and it may be helping with that or something else.  I am not an electrical engineer.  But the difference was not subtle.  If you have any hifi stores nearby, check out a shunyata conditioner or whatever products they carry (synergistic research, audioquest etc).  YMMV but it has been revelatory.  Some people say don't plug your amp into it.  Well I've tried my amp directly in the wall and it's clearly better through my Shunyata gear.  Cleaner, punchier, and better imaging.  Sorry to detail a bit but when I hear your journey, I always want to suggest components that may help even if they aren't on subject
