I stay 3 days together with Sakuma when he came to Italy around 1988,my friend of shop Nonsolomusica wanted to be his distributor but was too difficult to comunicate with him
Sakuma arrived in shop with 5/6 friends and brought some mono amp,phono and pre to demonstrate us
He arrived with espadrille shoes much bigger than his foot and with a rope instead a belt for his trousers and a big grey wool pullover.
His friends connected the system,mono and we gave an Altec 19,all signal and speaker cable was the black/red cable of 50 cent each meter.
He didn't believe cable.
Sakuma was listening in the armchair in the middle of the room and his friend/cooperate people behind him sit on the floor and when he stand up all stand up and when he sit down all sit down like he was a God.
Was very funny but we were excited because after listening always Jadis, ARC,YBA,Spectral,ML,Rowland,Cello,we listened something very special.
The sound was amazing,very full,dynamic with big presence and we listen natural sound on voice of callas with a dynamic never listened.
He sold this product to my friend of the shop and after he back to Japan we never had news or contact with him.
I was not interested to buy because i was not ready for mono system
