Tested using SEQ3 from Lindos CD2 - noise shaped.

Volume control on unit shown in dB, with 0dB as the maximum.

Volume needed to be set at -8dB to get the test level as close as possible to 0dB on the MS10.

'Super-Sound Equaliser' is a preset that gives the most realistic sound according to the manual.

Very poor distortion figures, phase error above 1k5 caused by using a single A/D on the output and multiplexing the channels.
