Hi, I recently purchased a Marantz 4400, and as it's in the mail on its way, I happen to run across the Pioneer CS-99's 10 minutes from my front door. I brought those home and connected them to an Onkyo 50w/ch purchased new 10 years ago, but the 99's, as talked about on may threads, just don't carry a lot of bass. I own a powered Dynaudio 250 SAT Studio Sub that was quite costly and it sounds great in combination with the 99's. When the Marantz gets here I would like to keep the Dynaudio connected if possible, and when another pair of 99's comes available near by, I'll scoop those up too and have four 99's in the corners of my listening space and the sub hopefully connected and tucked away. Any advice? I finally moved out of a tiny place and want to fill my new home with beautiful sounds!!!!!
