This is a good amplifier for those who no longer have
a turntable and dont need the phonopre,because despite
Sansui`s claim the phonosection in this amp is on par with
their high value units,the truth is its a single Opamp
cuircuit with a cheap and noisy Mitsubishi part and not on
par with earlier, cheaper units.
