Sell all, buy a cable for 3k first and start again.

Cable: Do you really think I can find a good cable for only $3k? I have a $4k budget. Maybe this was suggested and an "entry level" cable.
Syntax was having fun with you. Please don't take his post serious. The last thing you need to do is spend $3k on cable(s). A subwoofer may be a good thing.
