post #14296 of 20227

I am not entirely sure if there is a real benefit or not, it sparked my interest when I saw those videos last week. Lots of CD players and DACs do upsampling. By upsampling they insert zero valued samples between original samples (all the original information is still there) to produce 192kHz. They operate more optimally at those frequencies, the DAC is better able to use filters to move the noise to higher frequencies so you don't hear it. I have been testing 24/44kHz with 24/192kHz for the past hour, although its very hard to detect, I think the 192kHz does sound better for my system.

 

For those interested,

Wow, the difference between velour and pleather pads is actually night and day sonically however I find the velour pads quite uncomfortable (less plush) and itchy. Is there anyway to solve this issue?

Take out the plastic mounting rings and wash them. I actually put mine in the washing machine and then the dryer, but that was probably not the best idea. They got a bunch of lint stuck to them. The better way to do it is to hand wash with a bucket of soapy water.

Warm, soapy water (not dish soap but maybe a drop of laundry detergent). Squish them around and let them sit for awhile, then air-dry. Repeating the process should help soften them a tad more. I did not remove the plastic rings when I did this. It seems to help.

hey HE400/headphone experts

 

i'm getting a weird static on heavy bass notes, i started noticing a couple weeks ago.  it sounds very much like digital static, but i can only hear it on my HE400's, none of my other cans or any of my hi-fi zones.  changing cables/usb ports etc on the DAC/amp did nothing.  so it seems to only happen with my 400's, but its very, very digital in sound and only happens on lower bass, and i can only hear it when it's otherwise quiet (bass drops).  it's really bugging me, any suggestions?  is there something to check for this in the cans themselves (although i can't believe that because of how digital it sounds)

Do u still have the original grills on with the dustscreen? And also the original pads?
As With the jerggrill mod it can happen dust getting into/onto the drivers... U then have to blow them clean..very carefully...

Maybe you have your EQ causing distortion on the bass?

What amp are you using? It could be clipping.

It's not everybody's thing of course, but thanks for admitting it's a beautiful colored tarantula. =)
