Harman Kardon AVR 645

Not the most straightforward amp to use, but get the settings right, and the Harman Kardon AVR 645 rewards you with a rich home theatre experience.

EZSet equalisation results in excellent sound. Plenty of power in reserve. HDMI upconverting.

Plasticky controls. Terrible manual. No HD video upscaling. Not as intuitive as rivals.

Get the settings right, and the Harman Kardon AVR 645 rewards you with a rich home theatre experience.

Harman Kardon AVR 645

I had a yamaha 657, upgraded to a denon 2805, did not work well, the store changed it for the hk 645, the thing is great, sounds beautiful, and lots of power, surprising 75w/ch. The video switching to hd a little annoying but nice.

great looks, beautifull sound, underrated power, heavy built, usb connection (great for music from the computer)

plastic volume knob and little door, video switching to hd signals is not smooth, but after it switches looks very good

Harman Kardon AVR 645

Continued from above...

Good video and audio, when it is not crashed

Crashes every 2 to 3 hours of viewing, loses all signals, have to re-setup the receiver after doing a cold boot (what is this, a Microsoft machine?)

Harman Kardon AVR 645

I upgraded to this from the Harman Kardon AVR 520. It worked for several hours, then decided to cut the audio while watching my HD PVR. I went to the unit itself, and the entire receiver was frozen. Not even the soft power button worked. I switched...

Sound is great

Even though the composite inputs can now be viewed on the component monitor output, still, there is no way to see the volume/mute, etc. when viewing a component HD source. This is frustrating, because my components are in another room, so no way to...
