As for the "All refurbs are bad" ( i assume this was a joke?) Nope dead serious....
Refurbed products are sent BACK to the company, after a problem is found. When said problems are found, the product (Amp in this case) goes threw rigerous testing (More tests then an amp fresh off the line, still on the shelf.), Then its problems are fixed (At which point a "True" company [Not sure we got anymore of those in the good ol u.s.] would realize WHY wat happened, Happened, And fix that as well.), Then it goes back threw more testing, At which point if its deemed okay it is sent back to the customer. Meaning they SHOULD BE less problematic then a "New" amp.
