Review for Sophia Electric™ 274B Tube
By Mr. Gabbard, Tennessee

The tube made a dramatic difference in my system. The sound stage is more open and much deeper. There seems to be more detail in the music, as if there are more layers to the sound. Transients are much faster and crisper. It is diffidently worth every cent.
