4 out of 5 eggsNot without shortcomings

Pros: 1) Has 5.1 surround sound inputs. Ideal for connecting to a sound card or computer's onboard sound. Only requires three standard 3.5mm to stereo RCA cables instead of the usual one for stereo only.
2) Has subwoofer preamp output.
3) Excellent remote, all controls are available using it including front L/R and subwoofer levels.
4) Actual RMS power output at clipping was measured by me at 98 WPC into 8 ohms with both channels driven.
5) Uses simple monopole FM antenna instead of the older T dipole type.

Cons: 1) White noise (hiss) increases dramatically when tone controls are switched in. Noise increases even further with increasing treble control setting. You are probably better off keeping tone controls switched out using the Tone Direct switch. Took off an egg for this.
2) FM tuning is manual only. Pressing the up/down tuning button will not cause the tuner to find the next available station. All it does is change the frequency by .1 MHz. You then have to wait a few seconds to see if a station is at that frequency. Not a big issue if you already know the frequency of the station you want. Also, there is the usual memory preset capability.

Other Thoughts: I bought this for use at a computer station and except for the tone controls, which I never intended using anyway, this is a pretty decent receiver. I have it connected to a Creative Audigy SE sound card via the six 5.1 surround sound inputs and it does a pretty good job with computer sounds, music and DVD movies. Front, center, rear and subwoofer channel levels are easily adjusted using Creative's software during DVD movie playback. A computer's onboard sound and software can be used the same way. One thing to bear in mind is that sounds that would normally come from center and rear speakers, in a true 5.1 surround sound setup, are mixed into the front speakers. But their independent levels are still adjustable, for example, the virtual center channel sounds exactly like a real center channel speaker is there and you can adjust how loud you want it to sound.

4 out of 5 eggsQuirky, but works good

Pros: It has a fairly simple to use interface. Nice bass and treble settings, and the ability to turn off the modifications is nice, especially when using headphones. It is nice that it comes with an FM antenna, the last Onkyo I bought didn't. remote works well, and doesn't require you be pointed exactly a 1 square inch sensor on the front of the unit (I am looking at you Sharp!). Even though I am using it on a computer, having a mute function is rather nice. It also has other nice functions, like a sleep timer and whatnot. Remote appears to have all the functionality, and is laid out relatively cleanly.

Cons: The AB and headphone jack setup is a little quirky. The AB speakers are set up the same way as my antique Technics receiver, but both that and my Onkyo automatically detect headphones being plugged in and redirect output to the headphone port. With this receiver you have to manually turn off channels A and B to get audio through the headphones. I also find the double power on and standby thing kind of obnoxious, but I will likely get used to it, though it would be nice if it went back into its previous mode on power on.

Other Thoughts: I haven't used any of its virtual surround sound settings, so I can't really comment on them, but overall, it is an audio receiver, and it does what it is supposed to do.
Also, this is not natively surround sound, some people will see it has a virtual surround decoder and assume surround sound is present. That isn't quite true, it is matrixed 2.1, and it can add enhancements to make the B channel sound like the rear channels, but its inputs are 2 channel stereo, so it isn't natively surround. Its surround features are synthetic. I only have 2 speakers for it, so I don't know how good it is with its virtual surround sound. Just something to keep in mind.

4 out of 5 eggsNo HDMI, so why the combo?

Pros: 5.1 receiver for low price, comparatively.

Cons: Manufacturer's spec page says this is 2.1. But still says it has 5.1 connections.

Other Thoughts: WHY is this bundled and HDMI cable when there is no HDMI port on the RX-4503?
