In the September issue, Fred Kaplan reviews the Krell Evolution 505 CD player.
Can someone explain to me in layman's terms how it is that a CD player can operate in a "current domain" vs a "voltage domain"?
My understanding that as per Ohm's law, Current is the function of Voltage divided by resistance. So, what's within the chain of the components that provides sufficient resistance as to make the signal flowing from one component to another a function of the "current" rather than typical voltage?
If anything, I would expect the speakers' interaction with the amplifier to be in the "current domain" since the speakers provide resistance and require the amplifier to provide sufficient current to drive them. How does that translate vis-a-vis electronic components?
Furthermore, provided that there is something to the components being driven in the "current domain", as I understand it, the benefits of that would be that the interconnecting cables become irrelevant or close to it. Yet, Fred Kaplan states that when he hooked up Nordost CAST cables (in the current domain), he heard a pronounced difference vs. the Krell cables he used.
That statement leads me to believe that either:
a) The reviewer is deaf and he simply responds to more expensive shiny objects or
b) Current domain is a marketing ploy and there's nothing to it.
Either this circuit implementation makes a difference in terms of making interconnecting cables irrelevant or it doesn't.
Any thoughts are greatly appreciated.
