I owned a 4B SST and I ran it with Von Schweikert VR4 Gen III HSE loudspeakers (89db/6 ohm). Even at it's rated 250wpc (or whatever it was...I forget), the 4B SST would clip and shut down when running at relatively high volumes (95db-98db).
Eventually, I bought a 14B SST. The low volume performance was improved due to the better bass in the 14B SST, and the amp never clipped or shut down.
