Is this possible ....

For listening to music - I have the following:
- Ayre Evolution CD Player
- Audio Research LS 25 mk II Pre-amplifier
- Pass Labs 250.8 Amplifier
- Aerial 10T front speakers.

For TV 
- Aerial Center Channel
- Mirage back Speakers 

I want to buy an AVR that I can use to send signal to all 5 speakers ....
The center channel and back speakers are easy..... but 
How do I sent signal to front Aerial 10T speakers without changing cables ?
The Aerial 10T front speakers are connected to the Pass Labs amplifier which gets its input from the Audio Research Pre-amplifier.

Can I buy an AVR and use it's front speaker pre-out to pass the front speaker signal to the 
Audio Research Preamp -> Pass Labs Amp -> Aerial 10T front speakers ?

I understand that if this were to work that I will need to change input setting on the Pre-amplifier between CD player and some Aux input.

The Audio Research LS25 manual says you can use the processor rear input and front toggle switch to engage HT bypass mode, so that’d be the way to connect your AVR’s regular left/right pre-amp analog outputs to the LS25.

Thank you very much !!!
I really appreciate your help !

Hello - so I get this up with the Marantz AVR model 7012 and I go from the Preout on the Marantz and I go into the (single ended) PreProcessor input on the ARC LS25. I then put the ARC setting to preprocessor and yes it work buy I hear a slight hum or buzz coming from the 2 front Aerial speakers .....

Any idea of why that would be ? and how can I eliminate the buzz ?
