Absolutely easy to use a soldering iron if you are handy at any form of DIY. The only thing you have to be careful of is to "tin" the wire a bit before soldering the connection and in order to make a good solder you must get everything heated up - so a bead of solder touching wire and connector and iron tip will do the trick.
I am sure their are YouTube videos about soldering. The only thing you can't fix is SMC components as that requires a special iron but most high end audio is discrete anyway.
