HTIB systems are so popular, with value and ease of use coming in high on the list. The four updated HTIB systems from Yamaha certainly stack up pretty well: a couple of systems (YHT-791 and 591) with HD audio codec support are balanced out by a pair of 5.1 systems (YHT-491 and 391) that trim the price without leaving you totally out of the game. Holding pole position is the $850 YHT-791, packing 90-Watts to the seven discrete channels and 100-Watts in the 10-inch sub. Four HDMI inputs, HD audio codecs and even a iPod dock round things out and pretty much ensure you'll have the audio thing covered. If you need that DTS HD-MA and Dolby TrueHD support but not 7-channels' worth, save yourself $200 with the YHT-591 and up to 5-channels at 105-Watts each -- it'd be the direction we'd lean in. But don't take our word for it -- hit the link, check out all four systems yourself and let your own ears decide.
