I have purchased STRDA5000ES for about $999 from BB. I have yet to take the delivery, any recommendations about the product, if the product is bad, what is recommended in that price range.
I'd take the Harman Kardon DPR-2005 over the Sony any day, it's also all-digital and goes for around $750-800 shipped. Do a search on the avsforum.com for this model.
Best Buy is not the best place to shop audio, plus you have to pay sales tax unless you live in one of the very few states that don't have BB stores.
