The Yamaha 463 adds the following over the Yamaha 363
YPAO (w/ Optimizer Microphone) - auto speaker setup, XM satellite and Siruis satellite ready, Neural surorund sound. 105w versus 100w. These aren't major unless you plan to use saltelite radio.
The HDMI processing on the Yamaha 363 form page 16 of thier manual states that it is video only. Some of the earlier HDMI specs 1.1 and 1.2 while othier original intent and original specificatiosn stated they would pass both video and audio via HDMI calbel actually only passed vidoe. HDMI 1.3 will pass both audio and video. I would surmise that the Yamaha 363 is either HDMI 1.1 or HDMI 1.2 compatible nad not hDMI 1.3 compatible.
From the manual:
Audio signals input at the HDMI jack are not output
from any speaker terminals but output from the
connected video monitor.
To enjoy the sound from speakers connected to this unit,
– make an analog or digital connection besides the
HDMI connection (see page 15).
– mute the volume of the connected video monitor.
The Onkyo 575 has been repalced by a newer model 576 , but hte 575 is very good still.
Onkyo will upconvert composite or s-video to component output. HDMI input is needed for HDMI output; there is no upconversion to HDMI.
The HDMI input will not play audio to the receiver it will only pass it through; does not appear to be full HDMI 1.3 compatible. If you want audio from the receiver you need separate connections to the AVR.
See page 27 of Onkyo manual
Step 1: Connect your HDMI-compatible TV to the AV receiver’s HDMI OUT jack.
Step 2: Connect your HDMI-compatible player to the AV receiver’s HDMI IN 1 or 2 jack.
Step 3: Connect your HDMI-compatible player to an analog and/or digital audio input on the AV
receiver.
✽ Audio and video signals received via the HDMI IN 1 and 2 jacks are output by the HDMI OUT jack as they
are (HDMI pass-through), so even if you only make the connections in steps 1 and 2, your TV will output
sound. However, if you want to listen through the speakers connected to the AV receiver, in addition to an
HDMI connection, you’ll also need to make a separate analog or digital audio connection.
Step 4: Assign the HDMI IN.
Turn on the AV receiver, and then assign the HDMI IN (see page 38)
===============
Bottom Line , it doens't appear any of the recieveres ( AVRS) you listed are fully HDMI 1.3 compatible.
You will need to run separate audio cables!
Having said that both the Yamaha and Onkyo are good, fairly low end receivers from reputable vendors. Any of your choices are good!
