Farhad, Grounding is an interesting subject. While manufacturers are required to have their components built to specifications which allow for grounding, grounding itself in not necessary with every component. The one component in your system which SHOULD be grounded is the preamp. Every component connects directly to the preamp via interconnect cables so...in essence, every component is truly grounded as long as one is. Make sense?
I have dedicated lines in my house with a dedicated ground for audio. The Mephisto sounds the same with and without the ground and I notice no additional hum or noise.
