Had previously Bose 601 in (stereo) insert. The boxes do 30 years in service to a variety of amplifiers and then have 2500 DM tasted. Now I'm on a Yamaha 675 Audio Video Amplifier ungestiegen and thus to 5.1 .As I've heard a lot of good things about the devil and are very fair with test time and return, I took my yew Consono come directly from hell 35. What can I say. Did the Bose connected to the second amplifier output and compared directly: Bose 601 are still at rather quieter room volume and acoustic instruments in terms of transparency front, in all other tasks, the devils are just the beginning. And not only when viewing videos or XBOX, being there just gorgeous, but also in rock, ballads and orchestral pieces, where you turn something. Can only be recommended!
