If I remember correctly there is a review on www.stereotimes.com about the hydras. I think ( not positive ) it was mentioned that the makup of the 8 Hydra is a bit different then the others ,sound and internal make up. From what i can remember the 8 was the best ,as far as bass weight and authority....due to the beefier power supply. Not sure if that helps at all,,,,
Hydra 6 vs Hydra 8?
If I only need 6 outlets is the Hydra 6 as good as the Hydra 8? Whats the sonic difference?
