Three of the models are some of the first to be certified for iPhone and iPod compatibility, with the amplifiers also promising to enhance the sound quality of compressed MP3 files while they're at it.
The top three models – the '819, '919 and '1019 – can decode all the HD audio codecs, while the '919 and '1019 allow upconversion to HDMI. The top of the range '1019 also provides upscaling of all video signals to 1080p.
Focusing again on the top three models, you'll find a 'multi-format USB port' for connecting MP3 players. Direct digital signal transfer from the iPod to the receiver 'guarantees' the purest sound possible, we're told.
