I bought a pair of used SD acoustics speakers about 5 years ago-hardly used them as too big for the house! Now in a summer/party house with marantz pm66SE and sony cdp 991. Does anyone have any info on these speakers eg reviews on a website etc. Don't know what model they are but they look like serious kit. Do you think they will be ok with above amp and cdp (tried using a small receiver and speakers distorted on higher volume-amp probably too small??). Thanks for any info.
