It is always best to start from a base electrical perspective before considering external conditioning add-ons. You would be best served by separating your high-current electronics from low-current electronics and/or digital sources. It is not necessary for mono's to each have their own dedicated line, but it may be 'an ideal' from an electrical perspective.
More importantly, if you have the opportunity, separate the amps from your digital and analog sources. No power conditioner can make up for having independent lines separating high-current electronics. Summing a systems worth of current on one line is never preferable if you have multi-line options--no matter what might come after. Power conditioning alternatives should only be considered *after* you have established your system and electrical "base-line". Hydras are rated at 20 amps (4,6,8) and 30 amps (model 2), They will not "strain" any more than your panel-breaker no matter the current load--just match the breaker and Hydra current rating.
The best advice is to start with dedicated lines and evaluate options from there-- don't put the cart before the Horse! :)
