Elias:   Thanks so much for making this available This project is just amazing - videos are fascinating and the audio is spectacular. (And timely.  I just built a DAC so the 88/24 files were the first thing I really got to wring it out with!)     Great cross section of artists, and I...

Quote: That worked out pretty well.  I used 1k / 15 turn pots on the output channels.  After fiddling with them for a bit (0 db?  +4 db?) I just punted - I connected the line out of my iPod to an analog input of my (just finished!) amp and my computer to the USB/DAC input, both playing...

  Quote:     I'm guessing it's an inductive spike being coupled into either the audio or USB cable.  Try unhooking the audio cable, switching off the lamp, then plugging the audio cable back in.   If it's still working then it's the audio cable. If not, I'd suspect the USB cable.  (It...

Quote: @cobaltmute: Thank you!  I'd had "two volts" in my head from somewhere, and I just assumed p-p.   Should have looked at the spec sheet.   I got a couple of 15 turn pots today, so I'll see how padding it down works, just for fun.  I just realized that it's probably a moot point...

  Quote:   Hi Tom:   Using a software "signal generator" on the PC set at 0db, and with the PC output set at maximum, I'm getting a tad below 3v p-p on the output channels with both a sine wave and white noise.  DC coupled scope showed nothing when I turn off the input signal. ...

( overdriven = driving the amplifier with an excessive input signal, resulting in clipping on the output, which is what I was seeing when I hooked the GrubDAC to the Airhead.)   Good to hear that - are you running the computer "volume control" (e.g. the slider you get when clicking the...

Hi:   I just finished building the GrubDAC and was surprised how hot the output is.  I plugged the output into my Total BitHead and it immediately began illuminating the clipping LED, which I attributed to low batteries.  After turning the house upside down for new ones (and getting side...

Looks like - read the last five or six pages of this thread and you can see some of the ideas being discussed for locations and dates.  

Try re-posting over in the "Portable Sources" sub-forum and you'll probably get more help.     If you've got some time on your hands try scanning this thread:   http://www.head-fi.org/forum/thread/29323/the-diy-discman-repair-thread   ...and maybe you'll see something that might...

Thank Jude/recstar/volunteers/vendors for a great time! And extra thanks for everybody's patient explanations (esp TomB, Tyll & Kerry) to a novice.

Soundstage:  Forgot to mention this - you may want to do a search on "crossfeed", a feature some amplifiers incorporate to alter the soundstage.  The basic idea is that a delayed, lower level version of the signal from the right channel is fed to the left channel (and vice versa) to simulate...

Apologies in advance if you already know this, but here's my beginner's thoughts:      Think about where you'll be using them. In-ear monitors like those from Etymotics, Westone, etc. provide great sound isolation, are extremely portable and (to my low-end ears) sound fantastic and are great...
