Changing Hard Drive in a Melco

[simoncn]

If you look at the whole thread of discussion, you will see that the Crucial SSDs I used are no longer available and Donuk used a different model of Crucial SSDs. This shows that not all SSDs (even from the same manufacturer) are equal in terms of sound quality. Also, the comparison between HDD and SSD depends on the sound quality of both the HDD and the SSD, so if the user starts with a better HDD they are less likely to hear an improvement with an SSD.

Also, if all SQ improvements are caused by expectation bias, Donuk would not have found his new sound worse (because he was expecting it to be better). I am not denying that expectation bias exists but this does not exclude the possibility of real SQ improvements.
