Resale (not selling mine) 22 years ago 3k, average now on eBay 3500-4000.
They started out making mil spec and industrial amplifiers, not necessarily audio or consumer. Driving machines, flight simulators, etc. It morphed into consumer.
I recently took a good look at my MA6300 phono section, good specs. It uses a high accuracy AD op amp and a discrete RIAA section. imo no need for a separate phono amp. It has gain of 52 dB and SN of 81 at my cartridge level of 3.5 mV (rated sensitivity is 2.5 and SN of 90 at 10 mV). With my cartridge 28 dB of OL headroom (90 mV).
It looks old school, it's a love/hate thing, but the sound is good, by that I mean accurate with low signal degradation. I am not nouveau riche', and as plain Jane vanilla as you get. Lol
