To owners of MD players which utilise the HD-Digital amplifier I have a few questions if you don't mind. I have an MZ-R30 which has a normal amplifier which, well, just sounds normal ;-) Right, to my questions. 1. How does it sound compared to the normal amplifiers found in CD and MD portables? 2. I note line out uses the headphone socket on HD-amp fitted models with a menu mode to select 'line out'. Is the digital amp disengaged at this setting or does the digital amp feed line out?
