assessing talent in tennis is as subjective as assessing the merits of components and stereo systems. you are entitled to your opinion.
for the nth time, it is more useful to state the qualities of an amplifier that you consider laudable rather than to suugest that one will have to spend more money than the cost of an ayre to get a better amp. to my ears, i might be able to achieve what is in my opinion more favorable sound than i would get from having an ayre amp drive my mg 1.6 speakers, by spending less money than the cost of an ayre amp.
