Thinking of upsampling in my stereo system...

[RCduck7]

I heard the benefits of upsampeling my CD's on my PS3.

My PS3 is connected to an external DAC and when i go to the settings of my ps3 to upsample the cd i can see the higher rate displayed on the dac.

Allthough my receiver can't handle the 176.4 khz rate (then i have no sound), it can handle the 88.2 khz rate instead of the regular 48khz rate that is provided from a normal cd player.

There is a cd player from Nad that upsamples up to 192khz.

The cd player has an usb slot for your musicfiles but will they benefit from upsampling?? And will the samplerate be adjustable so receiver's can handle it??

My PS3 seem to upsample cd's but not WAV files.

I also seen a website that provides music albums that can take up to 4.7GB and provides 192khz/24 recordings to download at a price.

These files can then be played through a device that supports it, it seems.

Anyhow, it should be possible to set the 192khz upsampling lower as most receivers can't handle it.

Any advice or suggestions to get upsampling from either cd or files??

Has noone some positive experience with upsampling music??

When the display shows it, can you hear the difference?

Your post is a bit confusing, I am not sure what you are aiming for.

Many CP players and DACs use upsampling before the conversion to analog takes place. Upsampling works well, because there are very good interpolations routines that can be implemented on a chip. It probably also makes the analogue conversion and "postprocessing" of the signal easier. I would not feed an upsampled digital signal to your amp, just let the CDP or DAC do the conversion and use the analog output signal as input for your amp.

The is no reason to store upsampled files on a computer if the original source is normal cd quality 44.1Hz/16bits. Only if you have source material that was created at a higher definition it makes sense to store this (from SACD, from downloaded 'master' recordings, or from your own live music recordings should you have that). But if the source is 44.1/16 you might as well do the upsampling realtime by the DAC whenever you play the file.

Yes i can! There's a little more air to it and the highs sound sweeter to.

I can't hear any difference between a cd (running normal and not upsampled) and a WAV file though.

Yes, i suppose the source should be upsampled to really make a difference but i have to say that i do hear a difference when a listen to a normal cd that is upsampled when i select this option on my Playstation 3.

But to be a bit clearer, i'm looking for ways for higher definition audio files or upsampling files (if that is possible) to play on my stereo.

I'm not sure my DAC (cambridge DacMagic) does upsampling, The Playstation 3 does when i select the rate at the menu.

The dac only displays the upsampling rate, correct me if i'm wrong.

I guess i have to try a SACD and see what rate of upsampling it does becausse i do have one of the first PS3 models that came out that play SACD's. The newer models don't.

And maybe if that works i wonder if it is possible to extract SACD files from the disc to my harddrive to see it can do high definition audio through files to.
