AVSforum Dave Vaughn有詳細power rating報告...
http://www.ultimateavmag.com/avreceivers/pioneer_elite_sc-05_av_receiver/index.html從而估計sc-05 沒有THXultra2認証是marketing策略...故是不為...非不能也....(當然lx-71/81是否與sc05/07相同,另作別論...)
其實除power外... dac部份lx71/81都使用相同192 kHz / 24-bit DAC Wolfson WM8740 DAC...

yuppi hing,
有小小資料分享, lx-81用的一棵src: Burr Brown SRC4190,作用是兩聲道升頻(44.1KHz or 48KHz to 192KHz)

LX81 is use 4 SRCand 4 WM8740 DAC for all 7.1 channels
The main function for SRC is not 升頻, it is use for Time Base collector
