Alpine CDA-9815 vs Panasonic THD Meter vs SMD DD-1 OldSchoolStereo

Distortion? THD? Total Harmonic Distortion...that's what the Panasonic VP-7704P measures and this time the Alpine CDA-9815 is up for the challenge. How does it compete against the previously tested Alpine CDA-7977? See that video here:    • Alpine CDA-7977 vs Panasonic VP-7704P Dist...   As many of you know, the Alpine CDA-9815 has a built-in amplifier (IC) called V-Drive and was one of the first head units to require 10GA wire connected directly to the battery. The V-Drive amplifier was MUCH more powerful than previous head unit amps...but how does it affect THD or pre-amp voltage output? Watch the video as I test the Alpine with the amp enabled and with it turned off for maximum SQ.
