This brings back good memories! The year is 1993. I had a Pioneer A400 (not the X iteration) and was quite blown away then by the amplifier's clean, neutral sound. In those days, the A400 was regarded as a great budget amplifier, for those on a tight budget. Those with deeper pockets would usually end up with the Audiolab 8000A. I think the A400 still holds quite well by today's standards.
It would make a great amplifier!
Best regards
