I am really confused about Bryston Amps running at different wattage at different ohm setting 4 vs 8.

For example, the 3BST amp is 120 Watts per channel at 8 ohms, 200 watts at 4 ohms but in combined monoaural operation it outputs 400 watts at 8 ohm.

I would guess (as a lay man) that if you join 120 watts and 120 watts it should be 240 watts - the combined output instead is 400 watts at 8 ohm.

What is the ideal way to run a amp - sonically - at 8 ohms or 4 ohms?

Also, I am guessing that if you want to bi wire you have to use 8 ohms as all binding posts of the speaker have to be used.

Request some comments on 8 ohm vs 4 ohms operability for quality of sound.

Thanks for any advice.

Ash: If you run an amp at 8 ohms mono,you are combining the 2 channels together.Each channel sees half of the load (4 ohms),so it makes(in this case) 200w+200w=400w. Hope that helps.
