Vincent,
Jonathan Tinn makes a good point. There c-o-u-l-d be a player or converter which is better than the AX24 and also better than all the other players and converters you mentioned. Of course, if you had listened to all those which are popularly thought to be contenders for top of the heap, (those you mentioned and others), and had also listened to many others, and you had come to the same conclusion, and done so with an objective ear and evaluation, then your conclusion would appear to be based on a "rational" process of evaluation, and it could be a credible and defensible opinion. In which case, those who would seek to impugn your credibility simply because you did not share their opinion, and who would do so without also mentioning their similar process of evaluation and the results and t-h-e-i-r opinion, might in turn see their credibility questioned.
