Hi,

On several of these, the answer is of course - Yes, certainly. I have not got enough in most cases to either accept or falisify the hypthesis presented with any certainty.

In one case "instrumental" observation presented a small but repeateble difference, which may very well be audible and hence supports a potentially audible difference.

Meanwhile I notice that others, having found themselves without any reasonable argument to allow themselves to chalk up a "victory" (phyrric as it may be) took refuge to ridicule instead, how quaint.
