Hoping someone can help. I have been listening to PC audio since i got my XDA-2 about 2 weeks ago with jriver. Imported my itunes library and everything I have played displays 192 khz on my DAC. Since yesterday it will only play 44.1 on tracks that were previously showing 192. Yesterday when I opened jriver I got a message that displayed that it could only play 44.1. I tried going in the settings to change it back to 192 with no luck. Can someone help? Thank you.. Are you saying that all your original files are 192/24? Purchased from HDTracks and the like? None of them are CD rips (which would correctly display 44.1)? Anything I have played so far from my itunes library has displayed 192 up until Saturday. Yes all my CD's display 44.1. ;D |

You might also pop over to the jriver forum and ask a few questions? They might help if there was a setting or two that might need to be changed? I figured I'd ask over here first, but thank you.  |

I am doing that already.
BTW, is there not a multi quote function on here?

Assuming that your iTunes library wasn't specifically comprised of high-bit-rate files, I suspect that either Windows or jRiver was upsampling the output to 192k (this could be configured in several places). In other words, it could have been wrong before, and not it's right..... Therefore, the first thing to determine is the bit rate of the files you're playing.... Hoping someone can help.

I am just curious - do you hear any difference in the audio quality of the files between when it was displaying 192 versus now that it is displaying 44.1? |

Jriver shows input of 44.1 khz 2 ch. from source input. Output shows 44.1khz 24bit 2ch. using WASAPI. Where as before output would show 192 khz using WASAPI. Assuming that your iTunes library wasn't specifically comprised of high-bit-rate files, I suspect that either Windows or jRiver was upsampling the output to 192k (this could be configured in several places).

Still trying to pin down what is the source of your digital files? Did you rip CDs? Did you buy HDTracks? Or both? Do you know what the correct bitrate for the different files should be? It's important to know you are playing the correct bitrate (44.1 for CDs, higher for HD audio files), then figure out if something is or was up-sampling to 192. |

darylrsv4 did you look through the DSP settings? Maybe you have something turned on that is changing the sampling rate? What output settings do you have set?

AHHH, found it. ;D Thanks greenkiwi, not sure how, but a setting did get changed in DSP studio. Now shows audio path resampled from 44.1 to 192. Output settings are WASAPI. AudioHTIT - majority of my library is from itunes, 44.1. Hope this answered your question, I'm still a newb at this PC audio thing. Thanks again all.  |

Just a quick side note, jriver can be setup with zone switch, this would switch between playback settings based on the music playing.
It would allow you to up sample to 192 when you are playing 44/96 music and 176 when playing 44/88 music. I haven't poked around, they might have something that resamples dynamically like that, in a more direct way too.
Glad you were able to find the settings.

Just to clarify one thing here: Upsampling a file from 44.1k to 192k does NOT "make it into a 192k file". Changing a file to a lower sample rate discards extra musical information (whether you can hear it or not); changing a file to a higher sample rate cannot magically create information that wasn't there before. (I just wanted to make sure everybody here understands that upsampling a file to a higher sample rate is NOT the same as getting an actual high-sample-rate file. Likewise, converting an MP3 or AAC file to a WAV file or a FLAC does NOT restore the sound quality that was lost when it was converted into an MP3; you simply end up with a very good quality copy of a poor quality original.) There are two ways upsampling a file to higher sample rate can affect the way it sounds. First, different equipment (especially DACs) handle different sample rates differently. Even though the actual information is the same, most DACs use different filter parameters on files of different sample rates, so a 192k version of a certain file will sound different (and often better) on a certain DAC than the 44.1k original - even though the file itself contains no additional information. Second, the resampling process also involves filters which can themselves change the sound (which could be for the better).
Now, when you BUY a high-bit-rate file from someplace like HDTRacks, there are also a few reasons why it may sound different. One is that, assuming the mastering process was otherwise identical, the high-res file actually DOES contain more information. The other reason is simply that often more effort is put into mastering the HD version of the file or album; because it is a "premium" product, more care is spent in the mastering and conversion process, and in correcting minor defects or ensuring that quality is maintained throughout the process. So, it may sound better simply because it was engineered or mixed better. (Alternately, if the master was of poor quality, the HD version may not sound any different at all.)
Sorry to hear about your problem and I hope someone can help you get that fixed. I am just curious - do you hear any difference in the audio quality of the files between when it was displaying 192 versus now that it is displaying 44.1? Yes, there is definitely an audible difference between 44.1 and 192, at least to my ears. |

Yes, and it is important to distinguish what happens where...... The display on the XDA-2 will ALWAYS display the sample rate of the signal it is receiving from the computer. WASAPI will always relay whatever the player program sends it to the output without resampling it. (Normally, by itself, in DS mode, Windows 7 WILL resample everything it sends out. By default, modern Apple Macs also resample their output; unless you run a program to override that.) It is up to the player program whether IT resamples the sample rate or not. Some always do, some never do, and some, like jRiver, allow you to choose. Some even offer you selectable filter options for the upsampling process. (Every player I know of displays the sample rate of the file it is playing, and NOT the sample rate of the output, if it has resampling enabled.) Just a quick side note, jriver can be setup with zone switch, this would switch between playback settings based on the music playing. It would allow you to up sample to 192 when you are playing 44/96 music and 176 when playing 44/88 music.

I just got a HRT Music Streamer11 usb dac. The 7.1 direct inputs on my UMC-1 are being used for the dvd audio player.If I plug in the L&R rca cables from the dac into the cd analog input and use (direct), will this bypass the umc-1 dac or will it convert it A to D and D to A and use the umc-1 dac, or is direct a true bypass straight wire connection. I do have a niles axp-1 passive analog switch box to hook both to the 7.1 inputs,but I would need to buy more rca cables. I dont know if thats a good option. Any opinions or suggestions. Thanks

Okay, I've read through this thread and others, but still have a few basic questions. I've ordered an XPA-200 and XSP-1 as the start of a new system. I need an option for digital playback from a Mac, so I need a DAC. I was looking at the XDA-2, but was concerned at the redundancy aspect, already having an XSP-1. Am I better off going with a DAC-only unit (like a Schitt Bifrost), or does it matter? In other words, does injecting another preamp into the signal matter, and if not, how would I set the XDA-2 so that it's only being used to convert the signal and send it to the XSP-1. The XDA-2 would only be $50 more than the Schiit.
Finally, I'll probably be running a Toslink cable from the Mac to the DAC, since Apple TV has some limitations on output. However, the cable length may need to be around 15-20 feet. Does that pose a problem with the Toslink or USB cable?

It merely adds a volume control but is not going to be like doubling up on preamps. Also, it has more inputs and is more versatile than the Bifrost. And.. since it sounds like you need a USB input the Bifrost would actually cost you $50 more than the XDA-2 because Schiit charges an additional $100 to add the USB input. I don't think you will hear much if any difference between the two so I would recommend the XDA-2. It will match the Emo gear footprint-wise, too. |

This thread looks like the right place to post this.......
I have always enjoyed music but have been mostly HT over the last couple of years. As I upgraded my system, I have been enjoying music more and more like years past. I recently purchased an OPPO 105 to upgrade a LG BRP and am now enjoying the benefits of my computer audio via USB thru the USB DAC's of the OPPO.
I am currently using both the MC analog outs and the XLR stereo outs (toggle between the two) and am loving the sound.
My question is what have you all found to be some of the better streaming sources? I have really been enjoying MOG and also have Jriver on a trial basis but was wondering what other sources / programs are of high quality.
Thanks in advance for your suggestions.....

Hey tasdom, I use Jriver and am quite happy with it. There is an andriod app for Jriver called Gizmo that is fun as well. Sunday I was listening to my computer files from Jriver through my phone on the back porch. Cool that!

This revised DAC would surpass in features for example with the much more expensive Bryston's BDP-2 . So long as the price point of the XDA-? is marketed with the familiar Emotiva approach and then throw in Bluetooth control of the music library linked to the DAC using a Smartphone such as {ahem}  an iPhone and then the comparison becomes laughable. I'm waffling between waiting on an XDA with these minimally added features garym is citing and just going ahead and purchasing an XDA-2 paired with 2-XPA-1's for 2-channel listening. My dilemma is the longing for 2-channel listening against the visual barrage of XPA's, XDA, huge speakers and a computer. Even the much anticipated XMC-1 with its proposed DLNA certified LAN connection paired with the two behemoth amps will still require the XSP-1 to pass-through 2-channel audio. More links in the chain and more clutter. The one lesson the UMC-1 taught Emotiva is to have a solid product upon release. The one lesson the XMC-1 is teaching Emotiva fans is patience. It may take a long time but I'm sure Emotiva will eventually develop a DAC product which approximate this above wishlist. |
