Informative! Thank you.

I LIKE THIS! YOU EXPLAINED IT BETTER!!! ''NOW I GET IT!!!!

Terrific video!

Thanks for the explanation. So, if I want a better clear sound when I watch some movies, I have to connect my source to the DAC, then amp, right? And for the sound quality: I don't like much bass in the sound, I prefer natural balance with little bit of accent on speech clarity. I have class-D amplifier, and just wonder if it would worth the effort to add DAC to the system?

You've just killed my argument, I've always found dacs sound I've always been a analog fan boy but I've been checking out dacs lately, I've just learnt several mistakes in my audio chain.

great video

thanks bro

Excellent video, thanks for the explanation, much appreciated. One thing still puzzles me though - Bluetooth. If a standalone DAC has Bluetooth, when it Bluetooth-connects to my phone or laptop, is the digital audio file it receives for conversion to analogue getting degraded in any way by the Bluetooth connection? Or put another way is it better to use a cable, please? Maybe the answer is complex and your views on this would make a whole new video!!

So the amount that the digital audio is degraded by bluetooth will just depend on the original quality and the quality of the bluetooth connection. So AAC (Apple's Bluetooth standard) has a max transfer speed of 264kbps and 44.1khz 16-bit audio. Standard aptX (common on Android) does 352 kbps and 48kHz/16-bit. Generally speaking, if you're streaming Spotify or KZread, this means you'll have very little loss in data, but if you're streaming TIDAL Masters, Qobuz, etc, you're basically downgrading your hi-res files to lower resolution. There are some newer better Bluetooth protocols that can stream higher resolutions, but there's also some fluctuations in the quality. So even though it can stream 500kbps at maximum, you might actually still end up at 250kbps average due to the signal strength (from local interference and the like). So wired is typically best, but as Bluetooth tech improves, it's closing the gap on the quality difference.

What about modern onboard 3.5 audio jacks on PC motherboards? I've heard that onboard has improved hugely ... but would I should I get and external usb DAC to take it from PC to my Edifier R1700BTs's RCA/Aux in jack ... would it make a difference improvement?

I own two DAPs. An Astell and Kerns Kahn Alpha and a Shanling M6 Ultra. I must confess I like the sound signature of my Shanling best, as they have the AKM dac’s. The Shanling UA3 dongle has the same AKM 4493 as my M6 Ultra. If I hook the UA3 dongle to the Kahn Alpha, will it combine the two sound signatures into a hybrid signature?

So if you connect an external DAC like that to a DAP, it would bypass the DAC in the player, and the sound would essentially be the same as connecting the external DAC to your phone or any other device. There would be some advantages to a dedicated player from the perspective of reducing potential distortion or interference, but in terms of the tuning and sound, that would all be coming from the external DAC.

very good explanation. Thanks for the video

Can the DAC be connected to the TV and then output headphones so as not to disturb the family members with sound??? Please enlighten me 🙏🙏🙏

boy i found the high end store link here to bad their ant anything in the middle much but thats ok i use old sansui or my 20 junk amp boards to play with

All sound is analog, digital is only file storage.

Great video! But I'm still not sure about this: since my phone already has a DAC, what will happen to it when I connect a portable DAC? Which one will be used?

Connecting it via USB will send the digital signal direct to the external DAC without processing it, and then the Digital to Analog conversion will happen on the external DAC and not the phone.

@@edmondo785 Yeah, so basically, if you connect via a digital connection (USB, Optical, SPDIF), the external DAC is what get used to do the conversion. If you are using an analog connection (RCA, headphone jack, XLR), you're using the DAC in the device you're plugging into. On some devices (like a lot of Desktop DAC/Amp combos), you might have the ability to either use the device as a DAC by connecting to it via a digital connection, or use it as an Amp - bypassing the DAC - by connecting with an analog connection.

@@BloomAudio Hi, I just learnt there's SRC on Android phones, how does that affect sound quality? Will DAC be able to bypass it? And I heard only some apps, like Tidal, support bypassing SRC.

@@edmondo785 Yes, so there are some limitations with Android's sound system, but I haven't personally used Android phones extensively, so I don't know all the specifics for that. I'm also seen some mixed messages on forums as to whether or not the quality is really degraded or what apps actually fully bypass the Android SRC. So I'm not 100% sure on the best solution or options there.

Given my limited technical knowledge, I would be interested in knowing if a DAC can be employed through an auto system to upgrade sound from a CD or mp3s?

In most cases you wouldn't be able to directly upgrade the DAC in a car audio system, and because of other factors in newer cars (like a digital signal processing system that's specifically tuned for the cars speakers) there's not too much you can do outside of getting a whole new audio system.

You don't need a DragonFly Black in particular, but on most new smartphones you do need some kind of portable DAC for wired headphones since they no longer have a headphone jack.

I've never understood DACs, so if my source is X digital and passing through the DAC of my device, like a motherboard or an amplifier, how is another DAC going to help after that output? Isn't that just reprocessing?

@BloomAudio

Using an external DAC will bypass the one your device. The digital signal is unchanged until it's converted to analog (unless you have some other digital processing software), so the most important piece from a digital audio end is the moment it is converted to analog. Of course, once it's analog, there's a whole new set of concrens... :)

Can you prove in a double blind test that the DAC sounds better?

mqa ???

Please tell me what is a good file and what is a bad file. Just what constitutes one or the other. It can't be copying a digital file or it would not copy, there would be an error, if it does copy its exactly the same. If you are referring to someone copying a record to an MP3 format with a cheap microphone, or direct with maximum compression or even recompressing a MP3 file then that's not a bad file as such, its a poorly created file and nothing will restore it to the original recording. Using lossless compression files through a DAC would give a wave output that is indiscernible from the original. The quality of the DAC in most reputable brands products, not the just the high end, with a lossless or minimum compression file is sufficiently good enough to fool an oscilloscope that its not the original file and in a blind test I dare say the majority of audiophiles, though even they have a 50-50 chance of getting it right or wrong depending on where one stands on DACs, compression, amplifiers, speakers, environment and music choice. Also paying a mint for gear or peanuts.

So right, a CD quality .WAV would be a baseline for file quality, and then you'd have any number of lossless compression options like FLAC alongside of that, and then lossy compression which can run the range from "99% of people can't tell the difference" to "practically unlistenable." What the DAC does isn't just a matter of decoding the audio to produce the WAV file, it has to then algorithmically convert the digital information analog sound signal. While the conversion process has been "solved" there are still many variances between different DAC types that relate to how they process aspects of the sound, like transients, and how they compensate for timing issues in the processing of the sound. Beyond the processing itself, any DAC unit will also have a short analog signal path for its output. So the difference between DAC devices comes down to 1. The initial digital processing (is any noise or external processing added between the input signal and the DAC), 2. The specific algorithm used to process the signal (including things like multiple parallel DAC chips or running the signal through multiple passes), and 3. The final analog output (is anything lost or added between the DAC processing and the output terminal of the device). As a concrete example, I've experienced cheaper DACs which would often lose the first approximately .5 seconds of each track due to shortcomings in their digital input design. Some popular DAC chips have notable characteristics in any unit where they're used - like sharper or grainier treble vs. smooth treble - which someone might prefer for their setup. And some units have a good DAC, but a bad preamp, so when running with a line level out they sound significantly better than if you use the DAC units preamp/volume control. Some cheap units sound great. Some expensive units sound bad. It's up to the listener to try to find the best information and use their ears to find what works for their budget.
