Down sample DSD128 to DSD64 or convert to PCM 24/192?

[Lonely_Fool]

Hi,

I have bought some DSD128 files, but have forgotten that Devialet DoP only support DSD64. I am looking for suggestion on whether I should down-sample the DSD128 file to DSD64, or I should convert the DSD128 file to PCM 24/192, which approach should give me better sound on the Devialet USB input?

Also, anyone has suggestion on free s/w for Mac platform to do the conversion? I understand XLD can convert DSD to PCM, any other free s/w available on Mac for similar purpose?

Thanks,
