To anounce that Mac amplification is slow and un-natural is really odd to me, Mac gear do need good cables to perforn at its best maybe your cables were not good enough , your sources or other components at your system were weak I don’t know... the last thing that I can said about my Mac pre/dac & power system that it slow or un-natural at the contrary it’s sharp,transparent and natural . I have no wish to change it at the near future.
