Topic: Edirol UA-1D

[cgrooves]

I recently stated in another thread that I have been using this device to transfer DAT to laptop. Someone responded that it is not bit perfect. I requested some info on this subject, but apparently the info wasn't at hand or the request was not seen. All the spec data states that this device is a 16 bit digital interface. I have searched the threads and found where someone claimed to have knowledge of someone else proving the device NOT bit perfect. I have been pleased with the results from this device myself, just wanting to do a little research into it not being bit perfect. Can someone point me in the direction of some data supporting this claim, rather than just hearsay? Thanks.

I don't have one and can't point you to any data, but perform  a simple test yourself:

Transfer a DAT.

Transfer the same DAT again.

Trim both waves to be the same size and compare them using EAC's Wave Compare utility.  It'll be pretty apparent if it's bit-perfect... either the waves will match perfectly or they won't.

Or, instead of testing first, call Edirol and ask.  If they say it's not bit-perfect, no point in testing.  If they say it IS bit-perfect, I'd test to confirm.

That might have been my comment, sorry I didn't check back. Here's the proof, from an Edirol rep herself:

No apologies are necessary.
+T for the link!

"if the purpose of your transfer is preservation of the audio quality from your DAT, the loss of data is so insignificant that human
ears won't decipher any difference"

I think I'll continue to use this device. I've been pleased with the results so far, and it isn't like my recording, transfer and playback systems are all state of the art anyway. 

Thanks again.

P.S. If anyone performs the above suggested test, please post the results.
