Kinda new to the vintage Polks. I've heard that the SDA speakers are very picky on amplification requirements. Something to due with special grounding requirements? Is there any truth to this?
I've been looking at a good deal on some SDA-2a locally and wondering if they will work with a Denon 90 WPC (x6) receiver or a Sony 100 WPC (x2) receiver.
Any help would be great.
