New Aurender models; X100 vs N100 vs N10 vs S10 ?

[kenreau]

Is there a consensus on which digitial interface should sound the best into the Devialet?

I see the newer Aurenders are USB output only. Would there be a significant sound quality benefit to using an USB to SPDIF convertor (e.g. Berkeley convertor) to feed the Devialet? Or, just go for the S10/N10 models with Coax and AES outputs? I recall reading the new X100 has a high quality USB (from the W10?) port.

Thanks
