2 Stereo amps to be used in Mono...hookup?

@minkwelder 




So.....from preamp left and right out to left and right. In of each amp?

@georgehifi 



Well I guess that opens things up to weather the sound would improve?

Would it not have any benefit as far as better seperation...i.e. Imaging..Soundstage?  Seems to be like the jury is not quite out on one amp or to Mono....

As per manual..."Identical Signals"...
Would mean....preamp left out split to left/right input of amp.

Same for right channel....

I am not in possesion of 2 amps but may have an opportunity to land a second one for a friend or perhaps keep for myself if to bridge...given yours and Elizabeth's post I will pass on bridging.  I am really satisfied with my sound.   If I looked at my components I should probably if anything consider my delivery of music...I am a streamer using Bluetooth.....rblink Arcam....should go network..or ethernet cable....
If I had the A400's which are bi ampable I would consider for sure your passive diagram sent. I have a screenshot saved.

Thank you.

Thank you but speakers are not bi-ampable...

Speakers are 8ohm.
