Head shell with built-in head amplifier HSA-01 was greatly published by the Analog magazine.

The audition report of HSA-01 was published by the analog magazine.
It seems that it asks a critic teacher and the result with the sufficient top was able to be obtained.
Moreover, in order to hear the sound of HSA-01 more simply and conveniently, I have contributed audition scenery to the Instagram.
The sound which hung LP gas record in our audition room is recorded by a smartphone.
You could hear the true sound from the sound of the smartphone only a few.
In this Instagram, you can hear the the original record of the jazz of the 1950s to the precious 1960s etc.
Since I think that the record of an actual original record etc. does not almost have an opportunity which can hear it, I recommend so that you may hear it right or wrong once.
