I have two HK 5 channel amps powering my setup. 4 speakers in the back/sides. My mains are MA Silver 5i, so I prefer to use my Sub with 2 channel music. Thats a Velodyne 10 inch.

Give the 6 channel bypass a shot for your stereo music listening and let me know what you find. It really is quite an improvement to my ears, so far.
