This is a rather basic question but I wanted to make sure it would work. I found a used Marantz sr600 for a next to nothing price. ($75 bucks and it comes with a set of decent speakers and a sub from Cambridge sounds works, which I don't plan on using. and I was thinking about using it with my current receiver to power just the front 3 speakers. My receiver has RCA outs for each channel and the marantz has a dedicated line In for each. I am assuming I could use the outs from my HK receiver to the Marantz and use the HK to run my rear 4 speakers. My HK AV_254 says its 55rms a channel at 7 driven and the Marantz says 110 rms with what I am guessing x2. I figured even with driving 3 channels it would be more than the 55 my HK is making.

So my question is

1. Would this actually work?
2. If it did work would it be worth my time and would I actually hear a difference? Or would I have a sound delay or something else I could be missing
3.If it did work could I potentially hookup a second set of front speakers that would not have a lag in sound from the others?

Thanks for any help.

What kind of speakers do you have? This could work, you might hear a difference. Try it.

Am i understanding how to hook the two amps up correctly or is there something else required?

Make sure you do a microprocessor reset of the Marantz receiver to clear out whatever settings the previous owner has configured. If you aren't getting a copy of the manual, one can be downloaded for free from the Marantz Web site, and will include instructions for doing that reset.

You can connect the appropriate preamp outputs of your HK receiver to preamp inputs of the Marantz. Set the volume control knob of the Marantz to an appropriate value (0dB if using the relative volume scale) and then run the HK's speaker equalization software to get all of the speaker channels set to the right sound level.

Of course, you might consider doing the opposite, if the Marantz receiver is fully functional and its calibration microphone is included. My understanding is that Audyssey is more sophisticated than the equalization support provided by HK receivers.

In general, however, Klipsch speakers tend to be quite efficient. I doubt you'll hear any difference with the dual-amp configuration. Splitting the load between the two amps would only make a difference at high sound levels.

Thank much for the info. If you don't think the difference will be much better not ire it would be worth doing. Would I be better off going with a better receiver like a Onkyo 818 or denon 3313? Or keep my hk and get a emotiva 5 channel

There is no SR6002, so perhaps you mean the SR5002? Regardless, as Seldon notes, nothing really to be gained there with its use at average volume levels, rather you would be much better served upgrading to a model with Audyssey MultEQ XT (Denon 3313CI) or XT32 (Denon X4000) over simply adding an external amp to the HK.

Oh sorry its a SR6200

I think I will hold off on getting it. Save up for a new higher powered receiver instead of getting separates. I got the HK for free so I have zero loss for not using it. Would going with the 818 with xt32 over a denon 3313 or marantz sr5007/6006 that have the xt be better? I had a Onkyo 616 a few months back and returned it due to the 7th channel not working. I figured stay away from onkyo after that point, but maye the 818 is better build quality?
I then got a pioneer 1522 and that had video issues and the costco didn't have any for me to exchange so I returned it. I was looking for something in that $600 range. I figured with the new models coming out last years higher end ones might fall into my $600 price range.

Or ill just get another svs pc12+ and wait on the receiver until mine breaks.

Again, no real advantage to using it, other than perhaps powering Zone 2 via a model that has Zone 2 pre-outs.

I have klipsch rf 5, Rc7 and rs35 and I used to have a hk AVR 247 and it drove it plenty loud without any problems. In fact I compared the sound quality to an onkyo 804 (back in 2007) and the hk blew it away. Like the other person said, the klipsch you have are very efficient and won't make a difference.
