BEZdz Q3B-1 Belgium transmission transformer preamplifier

What the benefits of using active or passive transmission transformers are:
Stable circuit impedance in all range frequency;
Eliminate the undesirable digital sound from CD player;
Modify the mid/highs and shows quite good performance’
Powerful bass;
Density of sound and resolution are much better than RC coupling circuit.
