If this line transformer is connected between each equipments, it will become the sound which distortion decreases and the sound has a depth, spread in both sides and a reverberation.

It is because you were heard as the treble-sound region was extended more by the distortion. When used for the first time, since the tone quality was improved by these, the sound is not felt the powerful sound so the sound is not satisfied, if you hear the sound for a long time, the sound is a little distortion and natural sound will be noticed. .
If to take off it to a trial, one will notice a noisy sound hearing.
