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
