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...

LX81 is SRC + DAC fore all channels, LX71 is only use DAC
