Scott, imo, running all three dedicated lines is not overkill. Each time I've done it I've not regretted running dedicated home runs (no splices, no intermediate receptacles) for each monoblock and the front-end. (And in my case it's always four lines so I can separate the digital from my analog.). I've also never regretted using the Jena Labs deep cryo'd receptacles and avoiding the various flavors of platings that seem to pervade other otions. Once you've completed your lines, I recommend you leave the Hydra out for a couple of weeks, give things some good playing time to break-in, and only then put the Hyrda back into your system to evaluate whether it is needed or makes a positive contribution.
