Onkyo has continued to roll "X06" updates across its receiver lineup. Last month we heard about the TX-SR576 and TX-SR506 models, and now we get the TX-SR606 (not to be confused with the TX-SA606X). Apparently Onkyo wasn't too eager to mess with the success of last year's TX-SR605 receiver, the new model adds 1080i upscaling, two more HDMI inputs (making a total of four), and trades off Neural Surround in favor of Audyssey Dynamic EQ and Onkyo's Music Optimizer processing. The amplifier section and pricing look to be the same, which isn't a bad thing on either count: $579 (MSRP) nets you 90-Watts across 7 channels, all backed by the heavy transformer cores Onkyo is known for. Available any day now, this might look good with your stimulus check; or consider picking up a TX-SR605 on the cheap.
