The RXV-793 is a discontinued model dating back to about 1997 or 1998. It does not have dts processing, not even S-video switching for dvd.

I can't find any RXV-350, the lowest current RXV model on their website is the RXV-450. Power ratings of 110 watts at 10%thd at 1khz are pretty low. Typically you'd want a rating at .05% thd and 20-20,000hz, which would give a much lower number but would be much more realistic.

40wpc at .05%thd 20-20,000hz is probably a lot more real power than 110 at 10%thd at 1khz.

the RX-V350 is the lowest model here in canada, dunno if its available in the US.

Its also known as the HTR-5730

I just purchased the RX-V450, aka HTR-5740, and its miles better than my old kenwood... much better sounding... amazing how far technology has gone these days even an entry level receiver can provide 6.1 and very deceent audio.

Thanks for the help guys.


1. what is THD?
2. What are the 3 most critical things i should look for when comparing receivers?

Once again, all help is appreciated by this newbie enthusiast.

1. THD=total harmonic distortion. The lower the better.
Weak amplification results in higher distortion. 100 watts at 10% thd means the amp puts out 100 watts when the distortion reaches 10%. The same amp would reach a much lower power output at lower distortions. Thus 100 watts at .05% thd is a lot more real power than 100 watts at 10% thd.

The less thd the cleaner the sound.

Mainly when comparing specs you need to take thd into account when looking at power specs. It's not the only factor but it helps to compare power ratings at as similar a thd level as possible.

It also takes less power to output a 1khz fixed tone than it does to produce the entire 20-20k hz audible range, hence a power rating taken at 1khz is going to be inflated compared to one taken over the full 20-20k range.

Typically some mfgs use high thd and 1khz frequency to let them claim a high power rating.

2. Different people are going to have different ideas as to what are the 3 most critical things to look for in receivers, depending on their priorities.
At the entry level you pretty much want halfway decent real power. To run a set of fairly efficient 8 ohm speakers set as small with a powered sub to take the load of the low frequencies (the lows are the most power hungry) you can get away with surprisingly little real power--60wpc from a mfg with honest ratings can be plenty.

2nd priority for a beginner would probably be ease of use and an understandable owner's manual.

3rd in that class would be reliability and freedom from weird glitches. Often entry level stuff from Yamaha, Pioneer or Denon can be less glitchy than sophisticated high end boutique brands, just as a Toyota Corolla is less troublesome to own than a Lamborghini.
