They never got to compare Redbook vs either MQA or SACD with the exact same recording which is a real let down to me.
But then the converter in it is a BD34301EKV "Delta Sigma" based converter and not the best thing for "bit perfect" Redbook PCM CD conversion, like R2R dacs are.
As Delta Sigma can only give a facsimile of PCM, good for SACD and DSD.
