SAnSUi AU-5900 vs AU-7900 integrated amplifier vintage ?¿ soft battle

The content of this video illustrates the difference between the two integrated amplifiers Sansui AU-5900 and AU 7900. At first glance, these two integrated amplifiers are almost the same, but in fact they are very different.
the difference is in the front panel buttons, the final amplifier transistor.

I built an amplifier based on the circuit of Sansui AU70 during the late 60.
Then owned AU111, AU9900 and A80.
Still have a SS2 headphones.

Some 30 over yrs ago i tried a couple of popular Sansui but find its sound not to my liking. Rough, 2 dimensional & lacking in detail. Any small british amp from the same era will beat almost any solid state Sansui easily. Luxman was far better to me.
