I don’t use toilet paper or grilled cloth cover but add a metal mesh like the stock one of 800s

Past few years I pull out rough mesh type dust cover then immediately heard the changing. Then I creat holes with size 3mm on that cover, put it back, using until... This year, when I heavily mod my ibass SR1 to be a whole new phones, I found even fine dust cover alter the sound (there's other...

Imo best perfomance of hd800s is when using w/o dust cover.

Me too. It is not my fault. I feel backplate almost self crack, was a design flaw

Once forgot or misunderstanding what teachers told you, can remind yourself by seeing array of cars infront of signal light. Speed of ligh (R, G signal) is that speed of electromagnetic transmission. Cars speed is not light speed. Dont waste you brain think that flow of cars fast as green light...

He still thinking once the red turn to green, those cars travel at 747's speed just because he see all cars move simulanously. If those are not cars but snail (smart snail understand traffic light signal), he may think theres no electricity because snail is too slow

You checked your health recently?? You ask an electron inside accelerator??

The link in post #2: did they pull out the fuse then shortened it? I think the fuse can blury the contrast among cables. Power cable store electron that feed to the amp but a fuse is between them. Like you watching after a small gate then count how many people goes through it in certain amount...

I use a Furutech for powering hdvd800 headamp and really hear how it changes the output from hd800s drivers. Even a very short IC cable one pure silver stranded and one coper silver platted has at least, difference in bass range: kicking harder and punchy with silver, while coper with silver...

I try to feed ultrasonic (mean sound pressure is more than zero with above 20k) to Ru digitally then connect output of Ru6 to Shure1500 amp. The indication bar of the amp blinks -> Ru6 can out put more than 20k. On the other hand, I force R6 to work at 44.1k then I see no blink of indicator bar...

I did similar way, using input select button that hdvd800 and stax007tA have. I also use a switch box (all internal part bypass for minimal affect signal)... Or sometimes I compare listening w/o those support, use short memory by manually change the source. With some tracks, I even like the...

From Cayin: I understand it does not mean beyond 20k is impossible

Today I 1st time curious if Ru6 can produce ultrasonic, example 25kHz properly. Result: not sure it can or cannot (I have no criteria to evaluate). Noise heard clear as you listen to a average dynamic track by a typical headphones at volume lvl 4/100, L gain, 4.4 jack. It should be completely...

it's more about recording in pursuit of avoiding affect of low pass filter. Filter doesnt cut off really well at the right Nyquist frequency. To use 44.1 engineers have small margin to cut point, but still not perfection. With 96 or 88 it is ensure to cut after 20Khz and if, any unwant...

Delete. Duplicated.
