I recently took my pair of PLS-A speakers out of the back office, where they were being used as computer monitors (!). I had exiled them because they are so freakin' huge. But I was getting a bit weary of the cold but accurate sound of my Martin Logans, and rearranged the living room to accommodate the PLS-A behemoths. The moment I fired them up I was reminded why I loved this pair so much. The sound is smooth, accurate, with a beautiful sound stage and a spacious, warm sound. The speakers have a definite sound personality, which may not appeal to a lot of listeners, but which I find compliments the kind of music I listen to most: organ, choral, symphonic, chamber and opera. I'm not a tech guy, and understand none of the tech talk, but I think I will get better results from these if I bi-amp them. I'll need to use a 5.1 AV amp since they also function as the from speakers for my home theatre, so I'm looking at the Onkyo 805 7.1 which has a bi-amp option and plenty of power. Any thoughts or help would be appreciated. Finally, if you run across a pair of these beauties and have the space and floor trusses to make them work, they have been great friends to me and I would recommend them.
