@Curtis9 Hi!
Are you intending to use the 105 as a strictly 2 channel system? Your profile shows surround sound, and if that be the case, I am sorry to inform you that you paid too much and should have bought the 103.
While I think the 105 receives minor video upgrades, its the audio section of the 105 that has been upgraded. But you will only appreciate that if using the 2 channel DAC's that you paid for, that also allow the 105 to function as a 2ch preamp.
Oppo has made waves in the market due to their build quality and use of top quality components while selling at less than average prices. The 103 is almost a steal! The 105 is brilliant, but you must understand that it excels for 2 ch stereo.
Otherwise just use an HDMI cable, and enjoy!
