I have heard various Nordost cables in various systems whether at shows or at dealers, and of all the cables out there - they really do have a cool slightly bodiless tonality that has a treble lift. Nordost do a great marketing job in persuading us that they are the benchmark in terms of neutrality - but I am not so convinced.
@parrotbee , I agree with your assessment. Many folks misinterpret emphasized high frequency tones for neutrality.
In my opinion, neutrality means neither the bass, midrange, nor treble regions are emphasized.
Of course Nordost could sound 'neutral' with gear that has rolled off high frequencies.
