Shunyata Hydra

I think my response is a little simplistic.
The cabinet is bigger and there is more "magic gook" (the stuff that makes it sound good) inside.
And let's not forget the cryoed premium outlets.

The value of the 4, 6, 8 is that you don't have to purchase more power cords that would be required by 2, 3, 4 Hydra 2s.
As always, tailor your perspective to read:
"I'm not buying equipment, I'm buying GREAT SOUND!".
Makes spending the big-bucks easier...

Thanks guys. I'm quite happy with the Hydra4 except that I might upgrade to the 6 for more input outlets

I dont think you got your question answered did you?

I think the buss bars are of a different material and could result in some minor differences? I could be wrong!

There were NO buss bars in the Hydra-6, irrespective if what Shunyata claimed. It was all point to point wiring. This is a first hand info, since I opened mine.

Did they change the design ?

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.
