@listru - I don't know where you're located, but in the USA, Crutchfield sells the STR amp and offers a 45-day return policy. I think that will cost you $10. But yes, you have to pay first, then get a refund when it's returned.
I think they sell Parasound, also.
My local Anthem dealer was willing to match Crutchfield's terms when I asked them to do so.
