Default 16bit vs. 24bit? Kraken Pro

Will there be any difference in sound quality if I plug in my Kraken Pro to a 24bit soundcard?

Only if the source music is actually 24bit which most is not.

This. Really only blurays use 24-bit.

Thing is you won't even be able to tell the difference with your current headset and most headphones.

It's complicated.

You can run 24 bit sound but it's not better than 16 bit if the sampling rate is less for the 24 bit. The product of sample size and sample rate will give you a good idea of the overall quality of the sound on regular speakers, say up to 16,000 Hz range.

In other words, the sound fidelity is essentially the product of the sample size and the sample rate, so you would obtain a number in units of bits per second, which is quite logical and just what we would expect.

However, only ultra fast sample rates can fully capture ultra high frequency sounds, which come out as a shimmer to the trained ear, as these noises are actually out of human hearing range. So you end up feeling them and seeing them more than actually hearing them.

If you imagine a sine wave with a frequency of 20,000Hz, and you have a sample rate of 40,000 Hz, then you can see how you would be missing a lot of the information the 20,000Hz wave has encoded in it. In fact, if you started a 20,000Hz wave and polled it at 40,000Hz starting when the 20,000Hz wave is at a "zero" value, then you would actually obtain no information about this wave at 40,000Hz. If we bumped the poling rate to 41,000Hz we would get a series of triangular waves. This is why for doing good quality audio recordings you use 96kHz, which happens to be the same rate as a blue ray.

So in short you can notice a difference between 16 and 24 bit samples on any speakers in that the sounds feels fuller and clearer as at a common poling rate there will be more bits/second pumped into your speakers so the computer does a better job at emulating the real sound an instrument gives off.

Unless you're recording your own music you probably don't have any music that's 24 bit

However, most speakers stop at a range of about 16,000 Hz, so a higher sampling rate (such as a blue ray) will not show off better "shimmers" as common speakers have a small range of frequencies they can emulate compared to an acoustic instrument.

I hope my wall of text answers more questions than it presents!

24bit 48000Hz is intended for use with 5.1 sound sources such as Dolby Digital and DTS as both these technologies use compressed lower bit rates per channel than 2 channel 16bit 44100Hz CD audio

Upsampling 16bit 44100Hz to 24bit 48000Hz is no more than an exercise in futility as there is no (real or imagined) increase in quality and may even introduce such unwanted anomalies as jitter and crosstalk.

So 16bit 44100Hz CD audio is in fact a higher quality source which contains more information, which means higher fidelity should the source material not have been a victim of the 'Loudness Wars'.

1) the source and playback would have to be 24 bit
2) baseline headphones audiophile.. Sennheiser 650 HD
3) an excellent DAC or soundcard like RME, Lynx or some of the better DACs out there
4) remember you will need to be able to playback ASIO

Lastly, 24 bit is for Professional audio recording, at that level, absolutely 24 bit makes a big difference

Also depends on the mastering of the source material. Sometimes lossy DTS or Dolby tracks sound better than their lossless DTS-HD or TrueHD counterparts, for example, strictly because of superior vs. inferior mastering.
