As an aside, what solder are you using?
Some solder, especially this new fangled lead free stuff is a right pain to work with, it has a higher melting point and doesn't flow as well as good old lead solder.
For audio stuff I like to use WBT Silver Solder: http://www.audiospares.com/product.php?productid=1416
, I bought a big reel of it a while back because I was worried that ROHS might mean leaded solder became unavailable. Whether it sounds better than ordinary leaded solder I don't know, but it's lovely to work with, melts and flows really easily and gives nice shiny joints. Because it melts at a low temperature there's less risk of overheating delicate components, or melting the plastic/insulation of audio connectors etc..
