You've been bombarding us with questions on the Forums about the replacement for Onkyo's Award-winning TX-SR605 multichannel receiver, and today we have received full details of its successor, the £400 TX-SR606, which goes on sale next month.

Onkyo has also given us a detailed technical specification for the new TX-SR576 (£300) and TX-SR506 (£250) models, available from May.

The new SR606 won't cost a penny more than its predecessor and is equipped with the latest 192kHz DACs (digital-to-analogue converters) for all seven channels, advanced 32-bit processing and Onkyo's proprietary WRAT (Wide Range Amplifier Technology).

It delivers 7 x 140w power, has onboard decoding for Dolby Digital Plus, Dolby TrueHD, DTS-HD and DTS-HD Master Audio and has a Music Optimiser function for improving the sound quality of MP3 and AAC tracks.

HDMI video upscaling to 720p/1080i is included as standard, there are now four HDMI inputs and one HDMI output, and Onkyo has specified Faroudja's DCDi (Directional Correlational Deinterlacing) circuit designed to eliminate video artifacts.

The Audyssey 2EQ room distortion correction and set-up system is retained on the new model, but it has been further improved with the addition of Audyssey Dynamic EQ. The SR606 can also be biamped to further enhance sound quality.

The full technical specification of the TX-SR606 is listed below. We'll post details of the TX-SR576 and TX-SR506 in a separate story.
