Why didnt you just pull the real specs straight from Denon's website. Its been up for a while now. Funny enough, the Denon website doesnt mention HDMI 1.4 and lists HDMI 1.3a though.
They added web-setup, 2 HDMI in, a dedicated ipod-port, and a Audyssey DSX and prologic IIz mode if you actually want to use extra speakers in the ceiling. Neither which i need. They switched from Faroudja to Anchor Bay for their deinterlacer and added a digital input jitter correction.
But they also took away WLAN, DAB-radio, an optical input and also lost some weight on the thing.
I'm glad the 4310 is out since it put the price of the 4308A down with 25%. And after looking over the differences on Denons website, it wasnt that much to think about. Especially since i needed something new now.
