Excerpt: T he Harman Kardon AVR 660 does not support 3D video … as I write. But a firmware upgrade is promised for September 2010 to add this capability. Harman Kardon says that this will be as simple as downloading the firmware to a USB stick, putting it into the receiver, and running a routine to upgrade it.
Pros: Powerhouse, Bullet-proof audio performance, Very good video performance, iPod dock included
Excerpt: Home cinema amps from Pioneer, Denon and Yamaha have all set exceedingly high standards at this level, so the Harman Kardon AVR 660 has a tough job on its hands. The stylish, minimalist look makes a good first impression. The majority of buttons are behind a flap on the front; just a power button and volume dial are left exposed.
Pros: Attacking, powerful sound, beefy midrange and bass, decent detail, iPod dock is supplied
Cons: Hard treble, average dynamics, unintuitive remote
Excerpt: "Yes, I know it claims a mere 75 watts for its channels, but unlike most brands, that is 75 watts from all seven channels at the same time. Generally brands base their power figures on only two channels running. You are unlikely to find either a set of loudspeakers or a volume level that will trouble this receiver."

Excerpt: Somehow Harman Kardon continually pulls off the extraordinary feat of producing high-quality home cinema receivers that actually look rather nice. As one of the company’s high-end models, the Harman Kardon AVR660 is a big receiver. It stands an imposing 165mm tall. Normally the best you can hope for from an AV receiver of this size is that it doesn’t look overwhelmingly horrible. Yet there it is, looking elegant and stylish. Incredible.
