Whether there is a "house sound", is harder to argue.bigboss said:Theoretically, I can understand if you say that mains cables can reduce or eliminate RFI, but how can it produce a smooth & warm sound? So does it have the ability to change the properties of, say, a bright amplifier?
IMO What cables seem to do, is take what is already there, and make it better. As a result, the sound appears more natural, dynamic, airy and comes from a blacker background. I am quite happy to say this is my subjective opinion, and has to be tried out as an individual experiment.
I was at a cable demo for TCI cables. The system was so bright that it was a form of torture just sitting in the room with it. The system consisted of a Chord Dac 64 + Musical Fidelity M6i + Focal Utopia Diablo speakers .
As ever more expensive mains cables were tried, the hard, gritty edge was gradually replaced by a more natural sound, that approached musical enjoyment. At no point could it be called smooth.
I have also heard Audioquest NRG cables make a Linn Akurate system sound less sterile.
