What you've been advised isn't completely true. Yes, you can change the sound to the better or worse with changing cables, but the budget has little-to nothing to do with that. Higher budget cables are more of the fashion(definitely looking more nicer) than performance. Ideal cable has to match your speakers and amp and since it's hard to match parameters, you can experiment with ones similarly priced to yours. You can also experiment with simple wire that is available on internet with best OFC parameters and make your own cable or keep it as wire.
Definitely and very most definitely you won't need to spend $750 or $500 or even $400 for used cable to hook up Parasound A21. It's called skimming or pitching a product you don't really need!
If you want to feel difference try Signalcable or bluejean cables above recommended (once again not sure which side of sound will it take better or worse or something new you want to have), but most-likely your current budget AudioQuest is sufficient enough. No need for silver cables in most of cases especially with Parasound A21/B&W CM10.
Any cable you try trust me, you can stay within the budget of your current cable.
