Step 1 ..... Audio output connection
Connect the Optical digital audio output of your TV to one of the optical inputs of your PM6006 (There are two optical inputs available) ... This is the best and right method of connection ... The audio output of all the sources connected to your TV via HDMI or USB will be available through the optical output of your TV.
Step 2 ..... Speaker cable connections
You need a speaker switcher - 2 pairs in / 1 pair out ... (Do-it-yourself project - can be easily done - Send me a PM if you any need help on this) ... Connect your SR6006 front left+right speaker outputs to the input 1 of the switcher and your PM6006 left+right speaker ouputs to the input 2 of the speaker switcher ... Finally connect the left+right outputs of the switcher to your Paradigm Floor standers.
Thatz it, you are done ... Depending on your requirement, you just need to change the input on the speaker switcher.
Cheers
Interesting suggestion. I would have thought that doing preouts from SR6006 (FL and FR) into PM6006 would be a better choice. The SR6006 should also be able to simultaneously send signal to the preouts while also sending the powered output to the center channel (and the preamp output to the sub which it was doing already).
This is how I have mine setup, although I have a 2.0 setup, so now my AVR (Marantz slimline) acts as a pre/pro. (It still runs hot though, no clue why).
I'm trying to think of the pros and cons between the two setups.
The way I am suggesting, you would be using the Marantz PM 6006 as a power amp. You would probably want to turn up the volume knob to full, turn on Source Direct, and use the SR6006 as a preamp which also controls volume and tone of the sound being supplied to the PM6006. But you will lose the DAC and preamp section of the PM6006 and will literally be using it as a power amp. Plus side is also that you will be able to connect all your audio and video sources into the AVR and treat it as your control hub. You can then use the AVR for volume control, source selection, and can also program Logitech Harmony to do this at the click of a button and make it really WAF friendly.
The way you are suggesting - from what I can think (i could be wrong), what you would lose is Audyssey room correction and EQ for the FR and FL channels as you are bypassing the AVR entirely and feeding digital audio directly from the TV into the PM6006. You would also have to independently increase/decrease volume on both the SR6006 as well as the PM6006 every time you need to adjust the volume. Furthermore, both will have to be done at similar proportions, otherwise you will end up with unbalanced sound.
I'm also not sure if sending digital audio from TV to PM6006 will cause a slight delay in video vs audio, or in the two audio streams which are being played by different sources.
Upside is that you will get to use more functionality of the PM6006 including its DAC section, volume control, and possibly source selection (if you choose to plug a stereo source into PM6006 instead of plugging it into SR6006). Possibly for stereo audio listening, this might work out better - assuming the preamp and DAC sections of the PM6006 is better than the SR6006 (although to be honest, I suspect it is the power amp section of the PM6006 that is significantly better).
