The Hydras model 2, 4 and 6 are very similar in concept, design and material
construction as well as performance. They are purposefully specialized, direct devices intended to provide circuit to circuit noise isolation and system protection without interfering with peak or continuous current delivery.
The Hydra 8 and Hydra 8 V-Ray both v1 and v2 models are far more complex in material construction. They use direct independent circuit wiring instead of buss straps, an inner chassis housing the ZrCa compounds and large copper buss array, in addition to more elaborate filtration methods. There are definite and obvious sound differences between the 8 outlet models and the 6, 4 and 2 that are best qualified through evaluation.
