LS3/5A & Pass Labs

I am looking for new speakers to go with my Pass Aleph 3, Aleph P, and 9X16X8'celing room...concrete walls. I found a used shop that sells used Spendor LS3/5A speakers $550-$650. I wonder what you all think of this combo in terms of musicality, sound volume, sound staging, speaker placement etc...

thanks
