I do not see a mention of speaker wire. I would make sure to use a quality speaker wire (not zip cord) and then see where you are regarding sound.
Also, fwiw, I would be tempted to replace everything with Bluejean wire. They have been mentioned in these pages many times as consitently good wire products.
You can try different cable til you are blue in the face. You will get different results with all and after a few weeks will see the weaknesses in eveyone. You have to settle on something and if you want to save money just a well made wire will suffice.
my 2 cents...
