How to Get 24 bit 192khz Files From My MacBook Pro To Play Through The DAC Of The Fiio E17

post #1 of 40
Thread Starter 

Hi Folks,

 

I have a beginner's, stupid question to ask. I own the Fiio E17, and intended to use it with my MacBook Pro (late 2011) as the source. I bought some hi-res files from HDTracks.com (24 bit 192 Khz) before I realized that using the USB input on the Fiio E17 will only go up to 24bit 96Khz resolution. The higher resolution needs to use the S/PDIF input on the Fiio E17. So, the question is, how do I play the files I bought using the MacBook Pro as a source through the DAC portion of the E17? If you can't, then how do I play the files some other way to engage the DAC of the Fiio E17? If you could, be VERY concrete in your answer (assuming there is a way to do it)--which types of cable connected to which types of other machines, etc. Thanks so much for your help in advance.

The E17 takes S/PDIF, your Macbook Pro outputs that from its headphone jack (it is a combo jack, analog & optical out). You need an optical Toslink (S/PDIF) cable that fits the headphone out (3.5 mm) and hook it up to the S/PDIF input on the E17. I believe the Fiio L12 would do the job, but you might want to confirm that.

Thank you SO MUCH! I just ordered one. All the best,

I believe this is the cable KraftD1 is talking about.

Thanks, PurpleAngel. I just placed an order with Monoprice on Friday. Should have asked earlier. Will try that as well. All the best,

Not quite, you need a mini to mini toslink for that.

I assumed that the E17 came with a 3.5mm male to Toslink female adapter.

But I guess the cable your recommending works (MAC to E17) with out the adapter.

True as I just found out from the E17 spec, but any adapter should be avoided whenever possible.

All,

 

I can't find a definitive answer online, but I thought the MBP Toslink out was limited to 24 bit 96kHz? If it is, then the OP wouldn't gain much by buying this separate cable...just a different way of getting the signal to the E17.

Most likely, as you really need a highend AMP/DAC go get a true 24/192 out with no down sampling or other sync issues.  But if you already have such an AMP/DAC for 24/192, then there is really no point on hooking it up with the E17...

Hadn't considered the MBP's limits on optical output, if it is unable to do 24/196, sorry if my earlier post misled.

No worries, you can still get the cable and try it out anyway, as 24/96 vs. 24/192 is VERY HARD to tell apart, especially when your source files are native 24/192.

Thank you all for helping me out. We'll find out in a few days. I ordered the Fiio cable and it should be here soon. I'll report back on the outcome. I have a nay-saying friend who is convinced that the headphone output on the MacBook Pro is only analog out and NOT digital out, so that no cable will work. It's certainly worth a $12 experiment. Another question.....if the output from the MacBook Pro only goes to 24/96, will it down-sample my 24/192 files and play them at 24/96, or will they turn out to be a useless purchase until I get a better DAC? Just curious.......

Oh, I wasn't trying at all to attack your post- we're all trying to help. It was more I was having difficulty finding a "definitive" spec on that output jack.

 

To the OP- if you are set on getting 24/192 to the Fiio without any sort of downsampling or manipulation, consider a USB to SPDIF converter. Models like the hiface Two, Peachtree Audio X1, Musical Fidelity VLINK192, etc support a wide family of sample rates (I think the three here support 44.1/48/88.2/176.4/192kHz) and can in partnership with your Mac deliver a bitperfect signal to the E17 for decoding.

 

A few notes though...these converters run as much if not more than the cost of the E17. Also, if you are using iTunes, I don't believe the audio sampling rate is automatically changed when you play songs of differing rates. You'll need to change the supported bit depth/sampling rate in the Audio MIDI interface, close, and restart iTunes each time. Otherwise, if you have it set for 24 bit/96kHz for example, ALL of your songs may be converted to that before being spit out to the E17. Programs like BitPerfect and Audirvana are around to help perform this "switch" for you, but again they cost more money. Again, I don't own your particular setup, but these are just a few items of note I've come across in my research...

 

*EDIT TO ADD*

 

To the OP, I'm pretty sure it will downsample, but not 100% positive- it might not play at all if it exceeds the maximum bit/sample rate available as seen in Audio MIDI. Also see my notes above- you might need to take a few steps to make sure the MBP isn't mucking around with the signal before delivering it to the E17.

It should down sample as it is a hardware limitation of the MBP, so getting one of those USB to SPDIF (with the correct spec. as mentioned above) is a must in order to maintain 24/192 stream.
