24-88 files play fast
« on: 7 Aug 2012, 08:34 pm »
I just picked up a Fiio E10 24/96 USB DAC/headphone amp for my home PC. For the roughly $70 I paid, it works fine for desktop playback.

Last night I connected it to my big rig using a SB Touch configured for USB output to feed the E10 DAC.  In this configuration I found that 24-88 files play fast, like I turned up the speed control on a turntable.  All other sampling frequencies I played (44,48,96) sounded fine.  Anyone know what's going on?

 Russ,
Very often there are DACs that just don't do 88k (or sometimes 24/192 dacs don't do not 176k either), so they attempt to resample and it produces fast or intermittent sound.  Can you plug it into something like a MAC or Windows machine to look and see what sample rates are supported?

Edit:  a quick google search confirms my suspicions that the E10 does not support 24/88.  A fix would be to resample (in Squeebox) those files to 24/44 or upsample to 24/96.

No 24-88?  Oh well...  I don't intend to use this dac in the big rig so not a big deal.  I was just amused to hear my 24-88 files play back fast and wanted to know why. 

When plugged into my Windows 7 laptop and using Foobar for desktop speaker & headphone playback, the DAC plays 24-88 files just fine, so I'm good.

Thanks Ted.
