High resolution audio on a PC questions

Not a stupid question.

Audio quality can be improved almost indefinitely. I have listened to PCs, MACs, iPods, iPads… stand alone streamers (special built PCs that look like audio components) through all sorts of DACs. For example my headphone system (see my user ID) now has a $3,500 streamer, a $5,000 DAC, and a $6,000 headphone amp. This system sounds better than any of its predecessors… and there have been many.

So, a separate high quality DAC will sound better than using one in your PC. PCs are horribly noisy places for audio. A separate streamer will greatly increase the sound quality by getting the PC out of the equation.

Getting your feet wet. You have to decide how much climbing this road to better sound is worth to you. It can be frustrating and expensive or supply a lifetime of audio satisfaction.

I would start by getting a good set of headphones… this will give you the ability to hear the differences changes in source equipment you make. Companies like Focal make headphones that do not require enormous power to drive. Most folks after they upgrade headphones will get a separate amp, this will drive your headphones to have greater impact and dynamics. After that comes a DAC… this will add detail greatly beyond the little chip on your sound card. Finally, a dedicated streamer… this gets the PC completely out of the picture… reduces the noise floor and does amazing things.

About files. First there were CDs, then SACD, high resolution files to purchase, now streaming services. If you are thinking of any but the last, I would skip it. For $14.95 / month with Qobuz you get access to 500,000 high resolution albums and millions more. Qobuz is the preferred service among folks interested in high quality audio. Tidal is second. I recommend you start with Qobuz… if you climb up the audio ladder you have the right service with the most high resolution albums… and it will only get better over time. So, you join the service and listen… from your PC and any other device you own.

To connect your Onkyo to the PC through the analog output / input you'll want to use the line out on the motherboard (usually labeled front speaker output or something similar). You'll probably need a 3.5 mm plug to male RCA cable for this.

Sometimes onboard audio is perfectly fine. If you don't hear any noise through the headphone output or line output at the volume you want to listen to, then it's good to go.

Chances are you're going to be underwhelmed with hi-res files. Remastered content tends to sound worse because the trend is to simply make the recording sound louder (Google 'loudness wars'). It's probably best to find a version that's as close to its original release date to get the best sound quality. Oftentimes, that means the material is only available at CD quality.

I use a dedicated PC (mini X) with a dedicated player. My library is on an external HDD. The output from the PC goes to an external DAC via a re-clocker.

The sound is very good, bordering on excellent.

As to hi-res and remasters, etc, I confirm @yage ’s comment above: you’ll often find flattened dynamics in exchange for somewhat extended FR- often not even that.
On the contrary, however, I find that many classical music remasters of historical performances are quite good, especially the work done on the sacd versions.

I was thinking about getting into the high resolution audio fray using my PC. I was doing some research and found that it's recommended to buy some sort of USB DAC unit that supports high res audio. These range from less than 50 bucks to hundreds... I'm kind of not sure where to begin.

Can someone explain to me why I need a fancy external DAC, if most modern PCs are equipped with integrated audio chips adhering to the Intel High Definition Audio standard which supports sample rates of up to 192 kHz and 32 bit depth?

If I plug decent headphones into my PC's headphone jack (which is a current generation Mac Mini) and play 24/96 FLAC files using VLC, should I be able to hear an improvement over standard 16/44? If not, why not, and why is an external DAC better https://1921681254.mx/ https://100001.onl/?

Also, I have an Onkyo TX-8255 audio receiver (it's completely analog). Would I hear an improvement if I ran the signal from my PC's headphone jack through the receiver? (it doesn't have a line out). Sorry if these are stupid questions.

I got this,...

OP,

The DAC in your PC is located in a very noisy, vibration ridden environment and is not purpose built for high quality sound. Just being able to play high Rez files doesn’t mean they sound optimal. You might have a look at my system… every one of the 9 components weighs at least 35 pounds and performs a specific function. The more design effort, isolation, high quality components used, the better the sound. There is almost no end to this.

External DACs are available from a few dollars to well in excess of $20,000… I have owned and listened to at least a couple dozen from $100 to $22K. In general, the more expensive the better they sound… exactly like other components… streamers, preamps, amps, speakers and turntables.

The optimal sound will be from a system is to have similar and complementary components. If you want to do a single purchase and no more… then think of a USB or general purpose external DAC costing somewhere in the vicinity of your receiver.

Just running your analog output through your receiver may sound better… probably… but so many variables try it.
