I have been reading these posts with some consternation. A story of high hopes, fears of disappointment, virtually child-like innocence in the expectation of wonderous joys, etc. The hours counted, the bated breathe, as each of you who implemented the upgrade sits down to listen ... again. 'Will it be better today?'
One thing that strikes me about the posts and the very few extant reviews in the press about the V3 is the absence of considerations about the effects upgrading may have on system synergy and the related matter of psycho-acoustics, i.e., our experience of sound.
Presumably, the upgrade/modification will influence our experience of the sound quality coming from the source(s) as well as the all-important preamplification we use. In other words, it is not likely that in any system there is a constant against which the effects of such upgrades/mods can be 'objectively' assessed. Is is rather not the case that the 160 hrs many of the posts cite for critical break-in time are in effect the hours are brains require to 'process' the modified sound quality from the whole system we use?
