ERS Paper = No weaknesses!
ERS Paper around headphone cable with toilet paper rolls and cotton thread dielectric
3 months ago I wrapped my headphone cable in ERS Paper that was hanging from the cable with scotch tape, the ERS Paper was 5mm from the surface of the cable. It made it sound worse so I had to remove it.
Then I tried it again and used toilet paper rolls and a cotton thread to suspend the cable inside. Now the ERS Paper is separated 1+cm from the cable. I'm not hearing any weaknesses at all, it made it better in every way! Background is crazy black, there is more low-level detail and clarity than ever before!
The background got quieter which revealed more bass information. It gave the illusion of heavier bass. But the bass is more solid and doesn't interfere with the rest of the music. Everything is faster and more distinct, there is higher resolution.
The high frequencies are cleaner and whiter as well. It made everything more revealing and the jitter of my transport is more apparent now. The differences between tweaks for my transport is bigger than before.
The low-level details are clearer than before, but now I'm also hearing new detail that used to be cut off. The quiet sounds extend further and they are audible because of more clarity. A new world of very quiet detail has opened up. Those sounds aren't quiet because of dullness, but because they really are so quiet. The music sounds more true.
There are no weaknesses, everything got better. But the improved dynamics made it more fatiguing to listen, it reminds me of 16 months ago when I got my first vibration isolation rack where it took 2 months for my brain to get used to the extra speed.
Since there is more information in the music everything sounds louder, the only way I can keep listening is to reduce the volume with 3dB. My amp and DAC were fully wrapped in ERS except for the headphone cable, and now when I wrapped the last part of my system it made the biggest difference. Now the bass is so heavy and fast it makes me sick!
Taking it for a ride
When I upgraded the headphone cable from Nordost Solar Wind into Nordost Valkyrja I had to brace myself in my chair (link). When I wrapped the Valkyrja with ERS Paper I had to lie down.
