Just flip the switch

few ways you can do it...

i am using a power amp with switchable dual input

so for music i use Oppo balance output to my Bryston then to my Q900 speakers

for movies...Oppo to AVR > bryston > Q900

I have deleted all my earlier comments here a few times because my answer will not be correct without further details from you.

Is this what you want to connect for your system as shown below...

[attachmentid=7363940]

Mmm... if its connected like the above, its a bit confusing because you can just connect your AVR Pre-Out directly to your Power Amp so its not necessary to use the Int. Amp. Is it because you want the CD Player and Turntable to be connected to the Int. Amp so you need the Int. Amp?

When you play PCM Stereo from the bluray player... yes, the integrated + power amp will send audio out to your Stereo HiFi Speakers BUT your 2 Home Theatre Front Speakers will also have sound too.

You need to mention what AVR, Integrated Amp and Players that you are using AND what are your actual intentions. Are all your source players connected directly to your AVR, not to your Int. Amp? Difficult to answer without specific details loh.

Right now, if I assume you have a bluray player, I don't know whether your bluray just have a single HDMI out and a single Optical Out OR also have two Stereo RCA Outs.

Are you using just a single bluray player connected to your AVR?

Is this what you want?....
When you are using the bluray player to play blurays disc with 7.1 surround audio, you intend to switch off the Int. Amp connected to your bookshelf.
When you are using the same bluray player to play CD discs, you intend to use the Int. Amp connected to your bookshelf and don't want sound from your 7.1 speakers.

If you have a CD player and a Turntable... you should connect them directly to your Int. Amp... if they are connected to your AVR then what is your reason for not connecting to your Int. amp?

so ur case is 2 amp 1 spk.
your way can be use. just follow what u mentioned earlier.

bd to *avr pre out* to *int amp pre out* to power amp
cd to *int amp pre out* to power amp

int amp job become a middle man only

I think I know what you actually want. I did almost the same thing previously but I only used a Hegel H300 Int. Amp direct out to the 2 Front floor-stands, no power amp used.

I think this is what you want as shown by my poorly drawn diagram below...

[attachmentid=7366820]

I do understand why you would want your other sources such as the CD player and Turntable to connect directly to your Int. Amp because obviously the sound quality is much better than your AVR loh. Also, you can only connect your Bluray Player via HDMI to your AVR due to HT decoding (DTSMA, Dolby TrueHD, etc).

If you connect the AVR Pre-Out (Front L and R) directly to your Power Amp, you will get much better sound quality for your HT... BUT... you have to connect your CD Player and Turntable to the AVR which is okay but not as good compared to using your Int. Amp.

Aaah.... now you want to squeeze the best out of your system by adding in the Int. Amp specifically for your CD Player and Turntable. Fine, no problem... just disconnect the AVR Pre-Outs to the Int. Amp but you will not be able to use your Front speakers for HT!! IF you throw away the Int. Amp and use the AVR directly connect to your Power Amp, then your CD Player and Turntable needs to be connected to the AVR which will not get better sound quality compared to the Int. Amp, hehehe. You also want to "share" your Power Amp for all your sources (Bluray Player, CD Player, Turntable, etc) to just 1 pair of Front Speakers!!

WOW... pretty complicated and same for me too because I did it in a similar way.

Phew... after all my complicated explanations, the connection diagram above should tell the whole story better.

Its time to answer your question on whether you can do it that way.

Mmm... you can BUT do remember that BOTH your AVR and your Integrated Amp do have Volume Controls.

Normally, when we connect a Pre-Amp/Integrated Amp "Pre-Outs" to a Power Amp, its the Pre-Amp/Int. Amp that controls the audio volume so the Power Amp don't have such volume control.

In your situation, I think there should be an issue when both your AVR and Int. Amp can control the audio volume!!! The audio loudness will drop significantly so you need to push your Int. Amp Volume to maximum so that your AVR volume control can adjust the "correct" volume for all your 7 speakers. You just cannot use your AVR volume as maximum to allow the Int. Amp to control because your centre and other speakers will BOMB! There is a danger when you set your Int. Amp to max volume for playing blurays from AVR and you forgot to turn the Int. Amp volume down to play your CDs... your speakers will go BAM, POW, crackkk!

Here is what happened to my relative early this year... his connection is slightly different as he uses 2 bookshelfs and 2 floorstands speakers. He has an Onkyo AV Pre-Amp so he needed a 5 channel Power Amp to connect (not using 7.1). Unfortunately, he only have a 3 channel power amp and a Denon AVR !!! What he did was use the 3 channel Power amp for his 2 Fronts and 1 Centre, then used the Denon Pre-In for his 2 Surrounds. When he connected his Onkyo 2 Surround Pre-outs to his Denon AVR 2 Pre-ins, he had to turn up his Denon AVR to MAXIMUM in order to hear the proper surround loudness!! Unfortunately, turning volume to max is actually pushing the AVR internal "power amp" circuits to work very hard and at the same time, its internal "pre-amp" is still running. I would expect that heat issues for his Denon AVR should be a problem. I told him this at that time and I was not surprised when he told me that his Denon AVR feels very hot so he sold off his AVR and 3 channel Power Amp and then got a 5 Channel Power Amp for all his speakers!

The connection diagram below shows my previous setup before I sold off my Denon AVR-4520 and Hegel H300...

[attachmentid=7366822]

My Denon AVR only have 150watts @ 8 ohms so I wanted to make use of my Hegel Amp 250watts @ 8 Ohms which has better power and better audio quality for my 2 Front Floor-stand speakers. Similar to you, I only have 1 pair floorstands to use so I do need to "share" them with my AVR and Hegel, hehehehe. If I disconnect my AVR to my Hegel, I need another pair of speakers. If I throw away my Hegel, I lose the audio quality of a very good Hegel Int. Amp. Of course the best solution for me is to buy another pair of floorstands or bookshelves which are more suited for HiFi listening BUT BUT... my room is just not big enough to accommodate so many of my AV/HiFi gear plus speakers, not possible so I had to "share" my floorstands. That's why I had to compromise on buying a pair of floorstands which has the "best" overall audio quality for both HiFi and HT eventhough there is no such thing loh.

I bought my Denon AVR first, then I thought of getting an Int. Amp for my HiFi needs BUT I also need my 2 Front floorstands to "somehow" be shared with both the AVR and Int. Amp. Then I thought of this *ah-hem* "brilliant" idea. The solution is an Int. Amp with HT (Home Theatre) Bypass Inputs which allows it to function as a Power Amp only by bypassing or switching off its internal pre-amp circuitry so that its Volume Control is disabled AND the output is fixed at near to 100%.

I found what I needed in the Hegel H300 Integrated Amp which has a HT Bypass Input. When I play my blurays, I switch my Hegel knob to "HT Bypass" and woalah, my Hegel behaves like a Power Amp with the volume set to 85%. When I play my CD player, I switch my Hegel knob to "CD" input and my Hegel now goes back to normal integrated amp with the volume back to normal, hehehe.

I upgraded to solely use a much better AV Controller (Pre-Amp) as the main central unit for ALL my sources from DAC to Turntable to CD/SACD to Blurays so I sold off my Hegel H300. Then I added in a few Power Amps for my various speakers.

I don't actually know whether your Int. Amp can produce audio that is powerful enough when you turn its volume not to max. If you can get the proper loudness for your blurays, then your Int. Amp should be good enough for your purpose. BUT if you needed to push your Int. Amp to max volume, then you may have overheating issues or mmm... maybe audio clipping. You can try, and maybe its all good for you but ... I will just full stop here.



My personal unqualified view is to change the Int. Amp to one that has Home Theatre Bypass which should properly fit your needs here but I am not a pro in this so my views may not be correct. If you cannot afford to change the Int. Amp or still prefer to use the Int. Amp because of its excellent audio quality, then obviously the "replacement upgrade" will be impossible.

I hope my comments and views here helped you in some way. As usual, if anyone finds any errors here, please do correct me. No problem.

Optical has limitation of bandwidth

pre and power basically unleashes more power....if your pre or power has gain setting, try lowering down the gain setting first...

also....due to more power....try to reposition you speakers....moving it away from the rear wall may help you to reduce boom....

for music....i am assuming you are sending full frequency to your fronts....so having a high pass xover setting for your fronts will cut off the bottom bass...for music best to let the speaker roll off the bottom frequency naturally

No probs bro...glad to hear problem solved....may i ask what pre n power amp did u buy?

parasound p5 is nice!!..
