Caiman Question - Inputs, Oversampling and Outputs

[Frizzup]

Looking for someone to explain the Caiman specifications in terms of inputs, oversampling and output. The reason I ask is I'm using two methods of streaming music files to the Caiman, 1) Squeezebox 3 (max 48khz/24 bit) which is Coaxial connected and 2) Laptop running CMP/Cplay and optically connected to the Caiman. With Cplay I can have the Laptop up-sample using SOX or SRC up to 192khz/24 bit. I'm trying to understand should I let the Laptop up-sample or should I let the Caiman over-sample my streamed music to avoid multiple "samplings" happening in the audio chain.

i.e if I have a 44.1kHz/16 bit FLAC file through optical/coaxial or USB into the Caiman is the unit oversampling to 192kHz/24bit as analogue out courtesy of the WM8716 - 64x, 192KHz oversampling DAC chip built into the Caiman.

i.e if I have a 96kHz/24 bit FLAC file through optical or coaxial is that being oversampled to 192kHz/24

.i.e if I have a 96kHz/24 bit FLAC file through USB is that being downsampled by the PCM2902 USB chip in the Caiman then oversampled to 192kHz/24 by the WM8716-64x DAC chip in the Caiman

i.e if I have a 192kHz/24 FLAC file through optical or coaxial is that being down sampled to 96kHz/24 bit by the input chips then oversampled to 192kHz/24 by the WM8716-64x DAC chip in the Caiman.

I notice that the instruction sheets that came with the Caiman is titled "2 channel 24Bit/96kHz Audio Digital to Analogue Converter. Is the reference to 24Bit/96kHz for the max resolution for coaxial/optical input or the max resolution output?

If I've not confused people with the above trust someone can explain this to me

Cheers

The 24Bit/96KHz refers to the maximum incoming sigal on the coax and toslink.
Stay well clear of any upsampling. Let the DAC do its own thing.

Sorry for a thread necro, but the question is related.

Can the Caiman handle 192/24 over S/PDIF coax? I know optical won't do more than 96/24.
The WM8716 will do it, but has it been implemented?

Cheers.

It's not a problem of D/A converter implementation, it has to do with the S/PDIF receiver's limits.
The optical and coax inputs use the same S/PDIF receiver, imho.

Righto, thanks! :)
