Bin since 3 days owner of this receiver. Amazon order within 3 days received! Have unpacked after I had previously printed out all the operating instructions from the Internet and had the scope of the possibilities that offers this device records, if I can cope with it with my 68 with a little tummy ache the device. The 636 was intended to replace a 25 year old Kenwoodanlage. Once the wiring was finished and I had started the TV and the AV, everything went off like clockwork. Only the speaker calibration, then, then loaded into the net with WiFi the latest firmware, all with the simple user interface on TV. Now the big moment had arrived which the 5.1 system will bear. The first notes I drew with a Bluetooth connection between the phone and my joy was overwhelming, because what there 840 came to my ears from my 25 year old Heco Superior, I had not experienced before! Crystal-clear treble, bass I've never heard before with the Kenwood, especially classical music from the Internet offers a listening experience in a concert hall. Opera arias in the highest pitch crystal clear without distortion and clink! My Blu-ray discs now offer a cinematic experience that inspires me. The supplied CD Player Onkio 7030 transmits perfectly via Toslink. The tuner programming via cable BW presented as not a problem. Again, a nice channel separation of music and language (center), as on TV. My conclusion: Everything that is relevant to me works perfectly, so five stars for a "super box"!
