Thanks.

Sure go ahead and then when something happens to the house or your system and you have it inspected and find out that the house isnt grounded properly, then what ?
Lifting the 'Earth Ground' from power cables is common especially with source components. I would only do so if there is a problem like a humm (ground loop). That is the only way I would say it will sound better.
Of course like Riley804 means never disconnect earth ground from your house. Also never add a second earth ground to your homes electrical system unless you tie the 2 together
Well. i dont have grounded outlets in my listening room so i took it from a outlet in the kitchen but they are using the same fuse at least. So its rather easy to disconnect the earth in my case.

From what i have heard grounding give you a better bass and not grounded give you a more vivid sound.
There is no cut and dried answer to this, besides it can be dangerous. So you must know what you are doing. All cases can be different for best sound. Generally it is wise to have your preamp grounded and let ground run to the rest of your gear through the IC-ground. But even this is no safe bet, because sometimes your amps inputs may be isolated from ground. Somtimes you do get better sound letting your entire system float. But sometimes you do not, besides, as Riley has rightly suggested, this can be hazardous. You'll have to experiment and listen and best measure your chassis to ground for stray currents. The less current the better sound generally.
Detlof,
If you use higher or lower values on fuses compared to what is recommended in a cdplayer,preamp or poweramp does that affect the sound quality ?
Grisslehamn,
You know I never thought about that, besides I wouldn't do that. If too low, the fuses blow, if too high, the units blows. What I have done, is to substitute the stock fuses for those expensive German "gold"-fuses and, sadly, perhaps being tin-eared, I heard no difference whatever.
Cheers,
Grisslehamn,
YOu may want to consider one more option;

Dedicated earth ground for your audio system only. The medical grade outlets offer this feature, where the outlet can be ilsolated from the system or house ground. Depending on where you live in the country, and the age of your house, your house ground may not be that effective to begin with.

This is among the quietest of all the options. One has to be careful, if making the dedicated ground a wet ground, since you'll need to have a wire gauge large enough for your panel.

Johnss, if you are referring to an isolated equipment safety ground that is not connected to the main electrical grounding system, that is not acceptable anywhere in the US.....
It does work great for hunting fish worms though.....

The earth shall not be used as a means to carry fault current back to the source. The earth is a poor conductor.

Possibly if you are experiencing ground loop hum problems.
You could set yourself up with a safety issue though. Especially if you are feeding your equipment from more than one circuit and the circuits do not share the same Line, leg, from the electrical service panel. It is possible under the right fault conditions that a difference of potential, voltage, could exist between the enclosures of two pieces of equipment as high as 240Vac. That is if both pieces of equipment have their safety equipment grounds lifted.
