Benchmark DAC-1

Just attached my new Benchmark DAC1 to mediaCenter 23 on UBuntu and it sounds gorgeous. The DAC1 up-samples everything to 110KHz then outputs a sweet analog to headphones or XLR. Question: any suggestions on what to set Output Encoding to? Currently trying 88.2 KHz 64 bit 2 channel. Source is 44.1 16bit 2 channel (linear PCM WAV files)

I'm not an expert on this but you could try turning on the SoX resampling option in MC then use sample rates that are even multiples of your source material.
I.E 44.1k -> 88.2k or 176.4k
48k -> 96k or 192k

Like Bob, I'm no expert either but I'd set MC to do no encoding and leave the source signal untouched. If your DAC upsamples - great. Let it do that work in one step.

Keep it simple and don't mess with the signal more than you have to. I'd use MC for volume leveling / replay gain. That sort of thing - just the basics.

At least do a comparison and let your ears decide.

Thanks for the suggestions!
In other words turn off the Output Format and let the DAC1 do the upsampling and DA conversion.

RD James:
You'll have to set sample rates for <44.1kHz and >192kHz, and probably want to set channel mixing to 2 channels too, rather than outright disabling it.
Enable SoX and TPDF Dither too.
 
You may also prefer to upsample everything to the maximum rate that your DAC supports if you play random tracks rather than albums, since that will avoid sample rate switching between tracks.
