Thank you, bitracer, for your advice. I have been listening with SoX upsampling for a week now and as I said the sound is great. I couldn’t make out though what I liked best, with or without SoX. I tried again this morning the several possibilities, deactivated, upsampling by the power of two and maximum sample rate. The differences are tiny and I think it is a matter of personal taste. It all sounds good. The SoX usampling gives the sound a bit more dynamics, while without the SoX the sound is a little bit brighter. At least on my audiosystem (Macmini, Cambridge audio Dacmagicplus, Cambridge Audio Azur 851A and Monitor Audio Silver RS8). When I realise how the instruments and the voice would sound on stage in real life, I come to the conclusion that without the SoX the sound is the most natural. So, I have come to the conclusion that, for me, the Dacmagicplus beats the SoX.
