Default 24/192 basic question

Do you need a transport or computer that sends a 24/192 signal to the DAC to take advantage of 24/192?
I either use a cd transport (Shigaclone) playing regular cd's
Or Windows media player
Thanks.
Paul

Your source will determine sample rate and resolution.

24/192 audio is only available from downloads ( 2ch) Blu -ray players work with the higher format and some video blu-ray concerts supposedly have the audio done on 24/192.

So yes you can if you have a blu-ray transport in your PC or cd player ...

so connecting a blue ray drive via usb to my laptop will download the file (and play) a regular cd at the higher bit rate?
Thanks again,
Paul

No, regular CDs can only be played out at their recorded rate of 44.1kHz. Some software will up-sample to a higher bit rate if you want, but the advantages of doing that are debatable, depending on your hardware setup.

Default digital to digital converter

Are people using things like this Lindeman Digital to Digital converter ,
LINDEMANN.: Product & Features

Or is it more recommended to install a blue ray dvd player into my laptop?
thanks,
Paul

Long ago I upsampled a 16 bit/44.1Khz signal to 16 bit/96khz . On playback from the hard drive the 96 khz file sounded different and preferable. However doing this DOES NOT mean that it improved the sound ! Something changed and most likely it might be better performance of the dac at 16bit/96khz . But I never went back to it . Might have lost something too !

One needs to do a very careful test. But what's not there in the 16/44.1 signal can never be introduced by a higher bit rate or higher sampling rate conversion of the original 16/44.1 signal. The conversion could add artifacts of it's own.
As mentioned by abraxalito it would probably sound different due to the hardware.
Nothing like trying it out yourself.

First, I can't see why you would need 192KHz as a playback rate, 96KHz is plenty, tho many people want thins that don't make practical sense, so don't let that stop you.

Second. You need a player (source) and a DAC that can do that bitrate. Many good soundcards will do 196KHz these days. With USB it's just now becoming possible and affordable.

My Dell computer will play 192Khz thru it's internal soundcard, but there is no digital output so I'm stuck with the poor quality of soundcard circuits. I don't know of any Blu-Ray players that will output a 192Khz stream, but some might. Someone here should know. As stated above, if your computer has a Blu-Ray drive, you might be able to get the 196Khz stream (if it's there).

Can you give an example of the playback flow you wold like to do? Recording/Player/Output?

No, as stated , you will need a blu-ray disc done at 24/192 bit rate and you never want to upsample, upsampling has worst sonics than the original 16/44 and yes getting a dac capable of 24/192 is the way to go.

DAC quality is all over the place, the difference is astonishing, 24/192 is noticeably better then 24/96.....
