USB PCI Card

Posted by: pcstockton on 17 May 2010

This may not be the best place for this question, but many here might know. Naim is so gracious for allowing these discussions in their forums. Ill keep it short.

Is there a possible advantage to not using stock USB on a PC and using a nice USB PCI card. I thought with many people using Hiface's and Transits etc, there might be an opinion or knowledge.

Apparently they can get more dedicated bandwidth allocated to them blah blah blah...

anyone?

No. IMHO... Bandwidth of audio is 2x44100x16/8/4 (last 4 for 32 bit bus) = 1.3Mbytes/sec. Even your grannies PC can keep up with this....

Why is it that my buddy cannot play from a USB stick on his Mac? Well he can, but they stutter like mad and drop out constantly.

Without testing it, I wouldn't know. Something to do with buffering perhaps?

Also my maths is wrong - 44.1k (Hz) x 2 (channels) x 2 (bytes per channel per sample) = 0.2Mbytes/sec... give or take...

Theoretically you can have more (or more dedicated) bandwidth only if you have more than one PCI bus segment in your PC and no other device is using the segment where you put the PCI USB Card. It is a well known behaviour in case of some broadcast video editing systems using Firewire connected external video interfaces (like Avid non-linear editing systems with Mojo or Mojo SDI). However I do not think it would have any effect in case of a HiFace. If you have stuttering at the moment it can be a kind of configuration problem or incompatibility. If you have AMD CPU PC, you can have this incompatibility which can be solved to put a NEC chipset PCI USB card in the PC. I have a friend with this problem and it was the solution.

Thanks for the input everyone.

I will stick with the standard fare USB ports on my Tower as it seems there is no benefit otherwise.

I figured a dedicated USB would have some advantages.
