Using Onkyo TX SR703 to bi amp Speakers
I am currently using a Onkyo TX SR703 AV receiver to drive my Vintage Polk LS90 towers. This is a temporary setup until I can get my vintage Denon Equipment up and running.
I am am just using the front 2 channels for stereo and my question is I my thinking of bi amping the Polks using the rear surround channels and putting the listening mode into “ALL STEREO “. In this mode all 4 channels will receive the same input.
The newer Onkyo AV receivers have this as a setting in their firmware to do this and make the receiver a 5.1 setup. Since I am runnng only the 2 speakers I believe this should work.
The Onkyo is rated at a probably inflated rating of 100W per channel x 7.
The Polks are 8 ohm.
Anyone have experience with this.
