Pioneer is expanding its CES lineup with four new audio-video receivers, one of which supports the new high-definition audio codecs found in Blu-ray and HD DVD. The VSX-518-K, VSX-818V-K, VSX-918V-K, and VSX-1018TXH-K A/V receivers all feature Multi-Channel Acoustic Calibration with an included microphone for tweaking acoustics in the room, three 1080p-capable component inputs, and Auto Level Control for equalizing volume between sources. The VSX-518-K, 818V, and 918V all feature P.H.A.T (Pioneer Hybrid Amplifier Technology) power sources and support for WMA9 Pro over 5.1 channels, with the 518 dropping support for XM and Sirius satellite, iPod, and HDMI inputs. The big news is the VSX-1018TXH-K, with its support for 130 watts over 7.1 channels using a Direct Energy power supply, HDMI upscaling to 1080p, six digital inputs, and support for the lossy Dolby Digital Plus and DTS-HD High Resolution, and lossless Dolby TrueHD and DTS-HD Master Audio codecs. The VSX-518-K is priced at $199, the VSX-818V-K at $249, the VSX-918V-K at $349, all releasing in April, and the VSX-1018TXH-K will come to market in June for $599.
