Unfortunately, no one can really tell you what changes these cables will make to the sound of your system.
TMR, Upscale and Music Direct have a 60 day return policy. Upscale and MD stock both brands. If you’re planning to buy new, this is the way to go unless you have a local dealer who’s willing to lend you these cables for a home trial. There’s also The Cable Co. who lend cables out for a fee for a home audition.
If the rest of your cables are AQ, it would probably make sense to continue with AQ, but this is just an assumption in case you are unable to purchase and try or you’re purchasing used.
Also, in this price range you have Audience FrontRow, Transparent and Nordost, as well as Shunyata, etc.
