There was never a claim for buss bars in the Hydra model 4 and 6 units. The large copper buss bars are used only in the Hydra model 8 and V-Ray.
There are custom made buss straps (long solid flat copper straps) adjoining the outlets in the 4 and 6 models --instead of any point to point wiring. The only wiring in these two units is from and to the AC input IEC and EM breaker. This IEC input wiring exists in all electronics. The 7 awg. equivalent buss straps replace wiring between the three duplex outlets in the model 6 and the two duplex outlets in the model 4.
Performance wise, there should not be any appreciable difference between the models 4 and 6 as they are constructed similarly. There are substantial construction and performance differences between the model 8 and V-Ray Hydras, and the models 4, 6 and 2.
