Onkyo has on its hands this week two new THX Ultra2 Plus certified 7.1-channel A/V receivers which are available now. These are the TX-SR876 and TX-NR906, pricing at around $1,800 and $2,300, respectively.

Features wise, the only main difference between these two new A/V receivers seems to be that on the TX-NR906 there are “advanced networked audio capabilities.” Key features otherwise include HDMI repeaters for four high definition video sources, THX Loudness Plus processing, Audyssey’s new Dynamic EQ and Dynamic Volume technologies, HQV Reon-VX video upscaling to 1080p, multi-room support and HD Radio.

Sony is updating its line of upper end “Elevated Standard” A/V receivers with three new models. The STR-DA4400ES, STR-DA3400ES and STR-DA2400ES receivers are priced at around $1,500, $1,000 and $800 respectively.

Sony said all three receivers will be available later this summer. Key features include 7.1 channel surround sound, support for advanced audio codecs like Dolby TrueHD, a new graphical user interface and auto audio calibration.

Say you seek a multi-zone A/V receiver to go beyond your traditional two or three zone models. How about a receiver which can do eight zones? That’s the idea behind the new Audio Design Associates Suite 8200, priced at around $5,000.

The Audio Design Associates Suite 8200 can be combined with another Suite 8200 to give you 16 zones if you like. Beyond that, you’ll find this A/V receiver offering dual radio tuners to support XM or Sirius as well as HD and standard AM/FM radio.

Sometimes custom installers are the only ones who get access to the potentially really cool products. This seems to be the case with the new featured loaded DTR-5.9 A/V receiver from Integra, priced at around $800.

The new model, according to Integra, “features the same HDMI 1.3a repeaters and high resolution audio processing as the best-selling DTR-5.8 that it replaces, and adds two additional HDMI inputs for a total of four, 1080i upscaling of standard definition sources over HDMI, and Audyssey’s new Dynamic EQ loudness compensation technology.”

Home electronics company Onkyo is set to bring us two new entry level A/V receivers which are each available in black or silver finishes. The 80 watt-per-channel TX-SR576 and 75 watt-per-channel TX-SR506 are priced at around $480 and $380 respectively.

These new Onkyo A/V receivers offer dual source “powered zone 2″ capability, meaning the receiver’s rear surround amplifier channels to power stereo speakers in a second room while still listening to 5.1-channel sound in the main zone. They also both offer support for Audyssey’s new Dynamic EQ loudness correction technology.

New A/V receivers are always plentiful at CES. One is from a company called Sherwood and it is known as the Sherwood R-972. Price is around $1,800.

The Sherwood R-972 is Sherwood’s new flagship receiver. You get a lot of features for your almost two grand: 100 watts RMS per channel for each of its seven channels, HDMI 1.3b support, decoding lossless audio from Blu-ray/HD DVD and a very advanced speaker performance measurement system.

NAD Electronics, an audio-video manufacturer, is introducing three new A/V receivers to the market - the T 765, T 775 and T 785. The T 785 seems to be the most interesting of the lot, priced at around $3000.

The NAD T 785 offers up four 1.3 HDMI inputs for those who have multiple HDMI hardware pieces. It also looks to offer something called “cross conversion,” which delivers “all analog-video inputs (composite, S-, or component video) to HDMI with full quality.” A built-in calibrated microphone helps balance and adjust a multi-channel speaker system and “electro-mechanical configuration” reportedly makes the T 785 makes it easier to upgrade the receiver as new A/V technologies emerge.

Word on A/V Street this week is Marantz, a developer of audio-video gear, is out with a new and highly desired A/V receiver. The Marantz SR8002 is priced at around $2,100.

The Marantz SR8002 is a 7.1-channel receiver loaded to the gills with features. Take a look at this laundry list of its most pronounced ones: HDMI 1.3 repeating capability, HD Radio, THX Select2 processing, Dolby TrueHD, Dolby Digital Plus, and dts HD Master Audio as well as MultEQ room correction and calibration technology from Audyssey Laboratories. You also get multi-room signal distribution.
