connected-fidelity AC-2K Balanced Mains Transformer.

"I am amazed that the balanced mains transformer has so markedly enhanced the sound of my system which plays through occasionally lean-sounding full range single driver horn loudspeakers. There is satisfyingly more middle and bass weight and impact, more of everything, in fact, and nothing negative. I am very happy with the unit."
