It'sthe first time I could really compare the muses01 and the stock without too much time gap in between (time changing the amps). I must say I have fell in love with the muses01 again. The mids are so smooth and more forward. The soundstage is bigger. They produce more power too as I didn't have to turn the volume knob up as much ccompared to the stock ones.
There is something different between this second hand one with my original one. The original one when it being turned on, you can click "one" clicking sound from the inside of the unit; Where as the second hand one made "2" clicking sound?
Ps. I'll post a photo of my stereo setup tomorrow
