So, is that your 886 that's for sale?
And how do you figure that 6 months of use is only worth knocking 10% off the price?
Well, if you look at the sigs, the only common item appears to be the subwoofer (and I don't even know what the "/2" means, so maybe even that is not the same).
I think $900 is a reasonable starting figure for asking price, but I do agree to some extent in that I'm not jumping all over it either. OTOH, while I'm not always current with street prices, if the discount is only 10%, the seller got that for a great price indeed, if bought new. I don't think I've ever heard of an Onkyo/Integra pre/pro selling as new for 1k before. Though I have seen for much less than that, a refurbed, I think it was 885.
