Hear the sound or listen to the music

Over the years I have tried to feel the music in changing things in my stereo system. Last thing I have discovered was Bybee products name QSE and the new one iQSE. I try them cause the investment worth it and there was a 30 days trials. First I try the iQSE under the power distribution bar, with very good result. But the iQSE is suppose to be install inside the cover of a CD player for exemple, using the magnet included, so I move it inside my CD player. I order one more, but this time, it was a QSE a little larger device, to be install under or over a component, I install it under my power amp. The music is well separated from left to right, but also back and forth. Also there are much more micro informations, that is discovered in my CD collection. It takes about 2 days to settle down, you may try other positions in your system, all systems are different and react differently. If somebody have experiment such improvement with ByBee QSE and iQSE let me know.
