Upsampling, Can there be too much?

Perhaps, a blanket statement regarding up sampling is overly general.  Octave records has recently started mastering in DSD256, but prior to this they mastered in DSD64.  So, they have been upsampling the 64 to 256 and so far the reviews, to my surprise, are uniformly positive.

I hope you’re certainly not suggesting that results from consumer grade up-sampler is on par with mastering done in a professional studio?

I think that was my point.  Results are dependent upon implementation.

In this discussion, we are not talking about mastering in pro studio. My initial post was in context of upsampling at consumer grade level, which nets nothing; all that perceived detail is nothing but a form of distortion.

I do see your point, a DSD file professionally up sampled in a mastering studio probably carries more legitimate info across the spectrum. Personally, I prefer to listen files in its native resolution. 

Well, in the past (around late '80s) we do have 8x oversampling CD players.  That means we are very accustomed to 16bit 352.8KHz sound signatures.

Personally I tested myself on a headphone, anything more than 24/176.4 makes no difference to me.

IMO having 24/352 is perfectly fine.  And I like upsampling music playback, NOS sounded a bit rough to my ears, but some people swear by it as some holy grail DAC mode.  Definitely subjective opinion here.
