Thursday thing - Minidisc battery bays & Auvi's dead 1-Bit stereo

Today, Aiwa AM-F70 meets Sharp Auvi in a battery-extension face-off and an ears-on test of a just unboxed TRRS - TRS 3,5mm adapter intended to restore stereo sound to the Sharp MD-DR7 when paired with unbalanced earphones. The pretty photos and data I refer to came from these articles: RMAA AND REVIEW: AIWA AM-F70 MINIDISC RECORDER 16-BIT: http://ohm-image.net/data/audio/rmaa-... RMAA AND REVIEW: SHARP MD-DR7 1-BIT AUVI MINIDISC RECORDER 16-BIT http://ohm-image.net/data/audio/rmaa-... I shot the photos with a Fujifilm GFX on Cambo GFX rails. The lens is my favourite 80mm Sinaron Digital.
