I am pretty sure that all of the parts perform at spec right after installation and being used.
You have to understand, that the parts used, particularly for hi end equipment were not necessarily designed or intended for this usage. The different parts have different characteristics (audible) even though parts of similar design and equal value are used and substituted either by the designer, DIY, modder, etc. Given time the sound of the unit becomes more open, with better resolution, better imaging, overall sound, etc.
And to the naysayer that feels that modding of equipment by Dave Schulte, or any other company does not have any affect on the sound, consider that many manufacturers, including companies like Audio Research may come out with a Mark II as an example with replacement parts, etc. installed in the circuitry. The 2 versions of the same machine will often sound different. Also, during the course of the run of many audio products, the machine may well go through revision and changes, and as mentioned as an example a Mark II version may come at the end of such revisions during a run of a piece of equipment.
