Sony Liberty

Very rare set of compact hi-fi components, launched at a time when it became obvious a fair chunk of the audio market would go there : small, cute and unobtrusive.

Named PRODIGY in the USA, this was Sony's original LIBERTY system in Japan - with the Statue of Liberty as symbolic tag.

TA-YX7F : amplifier
ST-YX7F : tuner
TC-YX7 : recorder
PS-LX7 : turntable
SS-X300 : APM loudspeaker

Optionally, the SE-Q5 equalizer and pretty SU-Y5 rack could be added.

However gimmicky in design (but very coherent and well executed), we're still talking about respectable 6kg components and 2x 50W between 20Hz and 20Khz of Pulse Power Supply power - enough to shake your ear lobes.

Other features are BSL motors, a motor-driven volume control, RM-50 or RM-80 remote controls, soft-touch buttons all over with built-in LEDs, aluminium diecast enclosures for the TA-YX7F amplifier and ST-YX7F tuner, SBMC chassis for the cute as can be PS-LX7 turntable.
The SS-X300 APM loudspeakers' drivers are mounted on thick aluminium frames.

Pretty and well-built : no-headache high-fidelity. Ok, mid-fidelity.
But pretty enough and successful, sales-wise, in Japan, to even see a DIY scale model !

"Updated" in 1983 as Liberty CD, aka, outside Japan, SYSCON353CD.
