I disagree, I own this pair myself and have tested them on different DAC's/AMP's and cables, as well as interconnects. There was definitely a improvement on changing just the cables alone to pure silver cables.
I find it's very subjective others are capable of hearing it some can't.
It's just like many people cannot tell a difference above 60 Hz on monitors. I have a 144 and 360 sitting next to each other and can easily tell the difference between both regardless of if one or the other is being used side by side.
Then again I've been nit picking equipment for years. You know it's bad when you can tell when a monitor or TV is off of the 6500k white point because you used to spend 3+ hours a day a few days a week for years calibrating them. Some people are just more sensitive than others, I assure you 99.99998% of the population can't tell the difference between most of this equipment, or even calibrated or uncalibrated equipment unless it's just that far off of calibration. Until they actually AB them side by side and can actually see/hear the difference based on the equipment being AB'd.
That aside these are the best headphones I've owned period. Unlike other sound stage headphones they give you a accurate detail of positioning on everything this not only includes the surround effect, but depth and height as well. I remember the first time I used these on modded Minecraft I could hear a bird off of my 6 O clock, over my left shoulder but at a elevation that was above my head. I couldn't believe I could actually tell the height of where the sound was coming from it's something I've never heard from a headphone before prior to this.
The clarity, detail retrieval is also on another level from most headphones. It's solid across the spectrum some say there is a slight peak in the mids but I've never found it a problem
