Anyone have one of the "monster receivers" of the late/early 1980s from the "receiver wars" era?

Looking for info on those who have one of those "warm beasts" like the Pioneer SX-1980, Sansui G-33000 ,Nikko NR-1415....... and speaker pairing selections(old school 1970s speakers, mid 1980s, today's speakers....), cost of having a pro tuneup/repair and such.....

Update: Late 1970s/early 1980s.
Update 2: must be under 40y/o.

Those receivers sound 100X better than any modern one. Many of those were made on production lines by *hand.*

That's why they cost up to $6500.00 and more!
