BTW I finally managed to get that review to open. On previous attempts the site wouldn't load. I find a few things odd. Perhaps it's just me, but when they looked at distortion at 50V RMS they've...

They're good for 2 channels. (>128dB SNR A-weighted with reference to 300W @ 8R. Although, THD at <0.05% is nothing to write home about and certainly not over the narrow band they quote.)
