i wonder if any one had make a comparation betwen SHM-cd and Blu-spec cd? any big difference?
ps. i know that the format is not so much important than the mastering, but wonder if you take the same very good mastering in both format(if any) and compare if there is really a big difference and better quality?
In my opinion, there will not difference in transparency of sound (barely listened improvement) between traditional CD and any other.
Because these technologies (SHM-CD and Blu-spec CD) applied to give effect of more safe reading of CD.
Cases, where damaged only most low bites for each of lower byte of 16 bit word, can lead to losing of transparency, theoretically.
But I suppose, such cases have very low probability due sequental placing of bites on CD. For damages of these bits, defects should be exactly periodical on the disk in place of the lowest bits.
As rule damaging may be listened as click and/or silence (depend on applied processing) or periodical skipping (sometimes fast).
So new formats, if it give more safety of writing/reading of CD, may cause lesser clicks/silences/skipping, but not barely listened transparency.
