Sansui AU-20000 integrated Amplifier, fully working, beautiful condition, w/orig.Box

Up for sale is a beautiful Sansui AU-20K

Offered from my personal, curated collection. I select only the finest examples of vintage audio, prioritizing immaculate physical quality and originality above all else.
Condition: The unit just got back from my tech who addressed a small issue with the left phono channel and checked over the unit in total. It is sounding great on all sources and is all original.
The unit is in exceptional physical condition as well. There is one noticeable scratch on the top left side of the cabinet (see pic). There is also a small dent on the right panel (see pic). Outside of those two items, the unit is an excellent example of this highly collectible vintage integrated amp from Sansui's Professional line.

The original owner relayed that somehow, the store mistakenly mixed up the boxes and he was given one that denotes a BA-5000 (see pictures).
