Just as an FYI. There is a quality 12 gauge 20A cord included with Hydras upon the customers request. All dealers should be aware of this and inform the customer.
Often the reason better power cords on Hydras (or most other power distributors)offer improvement is that the cord to the wall is often supporting the current load for more than one component. It doesn't make sense to have high quality cords going to indvidual components if you have zip wire on the power center that feeds all or multiple electronics. There are certainly many options.
