There's one tweak I like but I am NOT making any recommendations here. It's called "Finyl"- you spray it (lightly) on your CD's and rub it gently to dry with a microfiber cloth (included). It's supposed to help the laser read the disc better, but it does polish the playing surface a bit. Supposedly you only need to use it once. I "think" it works, but it certainly does no harm- not like Armor-All- remember Stereophile's big discovery?! My cables are huge and heavy- just getting them to stay put on what they're connected to is tough enough. I even custom-ordered banana plugs for my Italian speakers, but the measurements are slightly off, so I wasn't able to insert them fully into the holes provided. I don't want to rain on anyone else's parade here, but High End Audio presents some exasperating challenges before you even get to sit down and listen. But my main objective is to get the best engineered recordings you can find First, no matter what your system looks like.
