Hi Bryon,
Interesting update. I have very little familiarity with Mac's, but in connection with the volume increase, does it seem conceivable that it might somehow have been attributable to a difference in the software installation on the new internal SDD, compared to what was on the original internal HDD? Either in the operating system software, the application program, the codec that may be in use to decompress the files (if they are losslessly compressed), or settings or updates that may be applicable to any of those things.
Did you implement the software installation to the new internal SSD by installing everything from scratch, or by using an imaging program to restore a recently generated image file containing the entire contents of the original HDD, or by using a cloning program?
Did the volume increase seem like it might perhaps have amounted to 6 db (keeping in mind the rough rule of thumb that a 10 db increase is subjectively perceived as twice as loud)? A 6 db increase would correspond to the bits in each digital sample being shifted up by one bit location. In other words, if at some point in the data path through the computer a 32 or 64 bit word length were being used, and the audio data comprises 16 or 24 bits, if the 16 or 24 bits were shifted up by l bit location toward the most significant of the 32 or 64 bits, that would result in a 6 db volume increase, corresponding to twice the voltage at any given instant.
Just some (obviously very speculative) thoughts.
