I've been following the various threads regarding the Sony ES receivers, and I am ready to pull the trigger on a DA4ES box to upgrade my current system, which is currently a recent Yamaha HT receiver driving an NHT speaker farm. There are no Sony ES dealers even remotely in my area. Given that I must buy via "mail order" or the 'Net, which dealers offer an "authentic" Sony ES receiver that is fully authorized/under warranty by Sony? Using the new Google "Froogle" service and plugging in "DA4ES" I get dozens of dealers offering the thing for $600 - $700, but no idea which of these are worth doing business with. I'm not the kind of guy who buys a box, uses it for 29 days, then sends it back expecting a full refund. Other than a receiving system DOA, I'm happy to let the mfr handle the warranty after the sale. So, who to buy from?
