Weiss Minerva Dac

All I know is what the display on the machines say. However, a friend (who brought is Oppo over to test out the Cary) says he uses a Sound Devices 722 Recorder: http://www.sounddevices.com/products/722.htm
This recorder has 24/192 capability and only has one aes/ebu and only one spdif in and out and it has no trouble handling 24/192. The Cary shows 192hz on the display when fed the 192hz signal from the Oppo. When I talked to my friend, he volunteered to call Benchmark (Benchmark Dac folks) as he knows them well. What my friend says he was told is that initially two cables were used to transmit the high bitrate signals. Subsequently, and for the last 5 years or so, digital cables, such as SPDIF have been found to be fully capable of handling 24/192 signals and thus it is no longer necessary to use two cables for high bitrate digital signals up to 24/192. My friend called using two cables to transmit high bitrate "old technology". I don't know any of this information personally, and this is obviously hearsay, but my friend does a great deal of recording and has a great interest in high bitrate digital recording. I guess I have answered my own query and hope that this helps.

Hi Luvwine,

A simple test if possible would be to connect a computer with a sound card capable of 24/192 connected to your cary's digital in and stream music via foobar or equivalent @ 192K and see if plays!

If it does then yes it works!!

Until then I will dig out some white papers on SPDIF and see it does allow it!

I have no such equipment so I cannot conduct the test. Am happy to learn what you find out, however. I do not claim to be an authority and am only reporting what I have observed and what I am told. Thanks.

Wish someone from the Industry could chime in on the same!

Below is a few threads talking about the same.

All conclude its RARE or maybe non-existent to transmit 192K/24Bits on S/PDIF perhaps I2s it is possible too.

Theoretical limit of S/PDIF is 25MBPS so a 192K 24Bit signal should be about in the range of 12MEGS which is on the border of supporting it after taking into account transmission loss. I don't know how the STACK is designed (maybe unfair to compare) but in basic networking(TC/PIP) there's a 70% transmission loss!!!

Hopefully we have more educated people tell us more about it.

What I am interested in learning is if any person has compared a Weiss DAC against a 'respected' CD Player & can write some comments on it.
I am more interested to learn how a CD Player performs against a computer / firwire DAC.
Thanks.
