My sister bought a Five Speaker Aiwa Bookshelf system long ago that was not that bad, but I took her to some stores and she wants to improve on it. She's not really an audiophile she just always wants better, so I'm going to indulge her. I ripped out the original wiring whose gauge was beyond me it was so tiny. The tinned copper was a glimmer among the pathetic shielding. I need some help b/c I'm not a know-it-all. She wants to better it as much as possible for 200. She really wants any of the HT setups I showed her, but they would intrude on her shopping. Anyway what wiring would be best to replace the original wiring. Should I just get the 14 gauge Monster XP through a friend at cost or is something else better on the cheap. The speakers really aren't that bad and I have not experimented much w/ wiring, so I'm on the fence w/ that and am not getting off till I figure it out. SInce the speakers don't really go low I'd like wiring w/ a reputation of having clear highs, I might just go buy cheap Home Depot 12 gauge, but would that be better or worse than Monster XP which I can get for same price. Second I was going to get her a Sony sub and that would use up her budget. I might even polyfill it, but I'll decide that after I hear it. This ends up w/ a 5.1 DD setup and she's never listened to DD till recently. Thanks for any help on this. If you have a better idea w/ what to do w/ the money I'd like to hear. I could change the receiver or centerpiece to the Aiwa, but what would be significantly better?
