ONe more for keeping them, at least until you try them out, if, after a proper setup, you still feel they are not holding their own, go for the upgrade to the QS8's, you will only be paying for the difference in costs from the QS4s to the QS8's, Axiom has in the past paid for the shipping while upgradeing during the 30 day trial period and I haven't heard otherwise.
