The D+PRO is not my daily driver, and I'm more interested in the digi+, digi+pro, and i2s-- where I find bypassing power is a fundamental improvement. So really can't say if stock USB power vs. 5V/3.3V LPS improves on the D+PRO...Buuut I've set this up just in the last few days, for another project involving making a good a/b testing platform for the Kali FIFO buffer (long story). So maybe I'll listen, then go to USB & see if it's diff. However, I noticed in your testing, you always go through USB (not GPIO)-- On the digi+ using linear power vs the stock USB power wart *thru the USB* didn't audibly change anything... also Hans mentioned this in his vid re: (usb/GPIO) whereas thru USB made no change. You can see my setup somewhere in the linux section, Kali... there's a pic.. I'm borrowing my 4x LPS's (LT3042 based, and cheap) supplies to play with this-- I'm cool if it measures the same, but would really like to see you re-run the tests taking it all the way thru GPIO, see my setup -- Then maybe play with the digi+/digi+ pro also :D 'AudioSystem' (http://bit.ly/1ruj0Zw) - 'YouTube' (http://bit.ly/1ULq4fT) - 'Twitter' (http://bit.ly/1q8dTgc) ------------------------------------------------------------------------ sckramer's Profile: http://forums.slimdevices.com/member.php?userid=20311 View this thread: http://forums.slimdevices.com/showthread.php?t=106213 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
