So, I recently acquired a Yamaha HTR-5250 that I have been using as my receiver for the last couple weeks. It was great find as even though it is about 9 or so years old, the owner kept the remote control, manual, and even the warranty papers (though useless now) in perfect condition. It was almost like buying a brand new (yet 9 year old) toy. Anyway, I was searching through the extremely long manual and on the back of the receiver are outputs designed to go to another receiver or amplifier via RCA out. I understand the amplifier part completely, but to connect to another receiver? Does the 2nd receiver act as an amplifier, or would you use it to maybe take the strain off the first amplifier by say, playing the center and fronts off one receiver, and the rears off another? I was wondering if it had any value whatsoever, because I have a 2nd receiver that is a Technics (some panasonic brand) SA-DX930 which is just as old, but had an overheating problem so I disconnected the original fan and put in a new one that was wired to run as long as the receiver was on, rather than only coming on when the receiver "thought" it was too hot. I got it for free a while ago and so I had no problem living with it and now it works as it was supposed to (better actually). Will I have any "upgrade" from using both receivers somehow? I'm getting an amp in next week specifically to run a couple sub woofers, but I'm looking at things to do to the main channel. Any input is welcomed as I'm still fairly new to home audio, coming from car audio.
