Can players not implement "peak extend" and still use the HDCD logo? How do you detect that reliably?I am evaluating a Yamaha S657 and although it has no HDCD logo, when a HDCD is played, it shows HDCD on the TV screen! While playing Reference Recording Sampler 2 on the last track which uses peak extend, there is a noticable drop in volume 1 sec after the track starts, possibly when the decoder kicks in. The previous track is the same recording without HDCD & there is no such problem.
Any ideas anybody? How can I confirm if this player really decodes HDCD because it has no HDCD logo or patent warnings? It seems to be based on Philips 720SA. Maybe the base player plays all discs but can be disabled to reduce costs? For example the Philips 720SA does not play DVD-A but the Yamaha plays it! So it detects HDCD, but since Yamaha did not pay for HDCD, it wrongly attenuates the volume to compensate for the peak extend which never got decoded? (Some HDCD players seem to reduce the volume on HDCD so as to not clip)
