A:AnswerThe difference is a “Voltage Regulator”. The 5400 will adjust the voltage should it decrease. All other features are the same when comparing the 5300 and the 5400. Both of these units will provide superior picture quality should there be electrical interference. These units also have the same amount of power banks to plug your components which also eliminates interference from your components. My suggestion would be to save your money and purchase the 5300. Should you have issues with your electric levels I suggest having an electrician check your electrical system.
A:Answermy understanding is that they have power all the time. they are labeled on the back so their is no confusion as to which components should plug into which outlets.
A:AnswerI placed a aragon 4004 on top of mine. I just made sure each device has it's own shelf. So if you want to place the amp directly on the panamax I'd say absolutely not.
A:AnswerThough the pamphlet isn't exactly clear about which one to use, outlet bank 5 which doesn't limit current to your equipment is appropriate for an amplifier which has a high current demand compared to other components in your system.
A:AnswerYes. Should be fine. The power conditioner does not have vents on top and puts out very little heat. You can always use cork blocks to give both units a little head room. Hope this helps!
