Context
Pioneer attempted to enter the semi-professional market with quadraphonic 4-track decks around the same time, positioning machines like the RT-2044 in competition with the Akai GX-400 DSS.
Market
The Akai GX-400 DSS is considered fairly rare. It has been described as a home studio classic and among Akai’s most ambitious reel-to-reel offerings. While some sources cite average sale prices between $400 and $800 (circa 2011), more recent discussions suggest values may range significantly higher, with claims of $2,500 to $9,000. It has also been noted as a deck that can be finicky and potentially problematic in use.
