I was wondering if downgrading, with sox, material with 24-bit and 192kHz samplerate, to 16-bit and 44.1kHz samplerate hurts a lot.
Not that I have noticed anything, but is this a dirty technical procedure?

Yes Nick.C,

This is my understanding too.

However I have some vinyls that I happen to found very good rips but they are 24/192, that is, too overkill.
Since the person ripped on such high-resolutions, does down-sample cause it to have artifacts like "horribly distorted" sound as I recollect someone said here that "downsample" was worse than "upsample".

OK, you've got a vinyl rip at 24/192.

The worst conceivable way of converting it to 16/48 would be to throw away 3 out of every 4 samples without bothering to apply an anti-aliaing filter (ie. just keep every fourth sample), and to truncate every sample to 16 bits without dithering.

Since the source material was vinyl, I suspect you may very well not hear any difference even after such a ham-fisted approach. A well-executed downsampling using a decent application like sox will be completely benign.
