The DMB purchased the Grateful Dead's final touring PA system in late 1995. This system was designed, sourced and built by Ultra Systems. This system was not the Wall 'o Sound.
The WoS was so large, complex, and costly to transport and maintain, it saw only a very limited life cycle. It would take an entire day (or more) to erect the scaffolding, arrays and de-bug the system prior to a show. At one point early on, Bear tried to convince the band that they really need two complete systems, in order to leap-frog over each other during tours. If you watch "The Grateful Dead Movie" shot during the Dead's October 1974 run,this was the swan song for the system, leading up to their hiatus from performing. Their self-imposed, slightly more than a year off, was the result of near financial ruin for the band, brought on by the Wall of Sound and an accounting scandal involving Mickey's father. When the band returned to performing live again, they did so without the Wall of Sound.
In addition to McIntosh amps, they also employed a number of Bob Carver's Phase Linear 400s. Jerry was partial to this amp in his guitar stack.
