Features:
a)High SNR.Since no power supplied,it cuts itself off from the source of interference.The thicken cover of the transformer effectively prevents itself from the electromagnetic interference.Comparing with some pre-AMP of vacuum tube or transistor tube of high level in tone quality,the music it plays sounds more peaceful and the machine is the best choice for audiophile who persues high SNR.
b)The sense of hearing is much better than the index.From the test index of frequency,this kind of pre-AMP without power isn't better than those with power supplied.However,the result of audition convinced that MC-9 feels more smooth and there is no obvious coloration and personality,so it sounds more natural.No wonder it cost the earth to buy some antique transformer of EC and UTC in the last century.
c)As a reliable pre-AMP without power,there is no need to concern about the changes of index of aging.And the accuracy and each index won't change by using for years.On the contrary,it takes some time for the run-in and the natural aging of the material of transformer,in order to get a better tone quality.
