  The receiver forms the heart of any home theater, allowing you to switch between multiple video and audio devices. With the HDTV revolution, you may need to upgrade an aging receiver to include high-definition HDMI connections. HDMI ports simplify the number of cables needed by carrying both audio and video signals in the same cable. Each model featured is a Home Theater Magazine top pick.
  
  

Pioneer VSX-918V

• For the entry-level budget, this Pioneer model offers only two HDMI inputs, so if you have a limited number of HD video sources, you won't miss the expense of adding more inputs. The VSX-918V supports both Sirius and XM radio and the built-in USB port works with any iPod that has a USB adapter cable. Although limited in its support of newer surround sound technologies, the 918V still offers better overall audio quality than receivers costing more money. The VSX-918V sells for around $350.
  
  

Onkyo TX-SR607

• The Onkyo TX-SR607 moves up the price ladder at just under $600 and is among the first receivers made to support the new Dolby Pro Logic IIz surround sound format. The SR607 also supports Dolby TrueHD and DTS-HD Master Audio decoding, for the best audio quality available from Blu-Ray discs. The unit features improved video processing thanks to the licensed Faroudja DCDi video processing technology. You won't be at a loss for connections with six HDMI inputs.
  
  

Denon AVR-3808CI

• For mid-range consumers who have a bigger home theater budget, the Denon AVR-3808CI provides full 1080p up-conversion for non HD video sources, so even older DVDs look great when played on large HDTVs. With the standard four HDMI inputs, there are ample additional video inputs for older standard-definition equipment. The Audyssey MultEQ XT auto-setup feature allows you to calibrate your specific room for the very best audio quality by plugging the supplied microphone into a front panel jack and letting the unit self-equalize. The AVR-3808CI is priced just under $1,600.
  
  

Marantz SR8002

• A high-end choice for most consumers, the $2,000 Marantz SR8002 represents the best combination of performance and features, including support for HD radio and THX Select2 certification for surround sound audio quality. As with the Denon unit, the Marantz includes Audyssey MultEQ XT automatic room equalization tools and full support for the latest Dolby audio technologies. Remote control junkies will appreciate the LCD screen with a full featured menu, eliminating the need to search through a multitude of buttons.
