I don’t think so.
If you only keep the B&W speakers ,
You need something like this :
Using one set of speakers with AV receiver and Lamp amplifier
I have NAD T778 setup for my home theater with Vienna Acoustics bookshelf speakers. I want to buy two floorstanding B&W 803 speakers and mid range two channel tube amplifier. Can I switch floorstanding speakers from tube amplifier to NAD and vice versa if I use secondary posts on the B&W speakers. Thank you in advance.
