Just purchased used Adcom 535 amp and am using it to power Niles outdoor speakers. Unit has A/B speaker switch. Didnt receive amp yet but was wondering if I will be able to play same source material inside while also listening to it on outdoor speakers. I own Marantz SR19 receiver which is multi room capable. On another note, I am powering Martin Logan Aerius 1 Speakers which are rated 80-200 watts at 4 ohms. Receiver puts out 110 watts per channel on front,center,and rear. Would a separate amp significantly improve sound on front speakers for music listening which is what I mostly use system for? Thanks for any input !
