Impedance Resistance

I posted this in another thread, and I notice that there are quite a few people asking about it so I thought it might warrant a thread of it's own. I wrote all of this fairly quickly, and I'm not sure I understand all of the concepts perfectly. I know there are quite a few other people here who probably understand this beter than me, so correct me if I state anything incorrectly. I found pretty much all the other info I read on the subject to be accurate, but sometimes misleading. Here is my explaination of why resistors help sound quality, and why lower impedance... read more

How To Clean The Filters

If it is metal mesh, no tool is going to clean it up. However, there is still one way: Get some pharmacy grade peroxide solution (H2O2 in 3% or 5% solution), pour a little bit in a small container and dip only the metal mesh part of the nozzle in. Let the metal mesh submerges for 3~5 minutes and allow the magic to happen. Dips the metal mesh into water to rinse, then dry it up with tissue (you might need to repeat the whole process several times before all the wax is cleaned). Be sure that the nozzle is always facing down so no liquid will go into the housing. You... read more

An Interview With John Grado

  • by ClieOS Contributor

[ The following is an original John Grado's interview done by Zanth, posted on 7/29/05 ]   Well folks I just had one heck of a time chatting with John Grado of Grado Labs (like that needed to be mentioned ) I rang him at just after 9 am today and we talked for a little over three hours! I was pretty nervous in the beginning but John was so laid back and forthcoming that I soon settled into a comfortable state and it felt like talking to a friend rather than me "interviewing" a manufacturer. I just arrived at work so I can't write too much just yet, but I will... read more

Syncing music and making playlists work with the Astell & Kern AK100 and a Mac

  I figured out how to create playlists on my Mac and put them on the AK100. It's a bit of a PITA but it works.   First, I use Markspace Android Sync to copy the iTunes playlists and music I want to my micro SD card. I first set that up to tell it the types of files that can be played, as the default doesn't include m4a, and others. This re-creates the playlists in a folder/directory named Markspace/Playlists on the SD card and puts the music in Markspace/Music.  I open up those playlists in BBEdit and change the paths from "../Music" to "/mnt/SD0/Music" (Note!... read more
