Air Tight ATM-300R Stereo Power Amplifier

Abolishing Vanity and Extracting Musicality   Even now many audiophiles are still longing for 300B direct-heated triode valve. We too, were captivated by the charm of this valve. Our approach is to pull out the full potential of 300B valve’s musical soundstage without any additive coloration. As a result, we could achieve a goal of timbral purity and tonal realism by means of 300B’s idiosyncrasy. Detail Researched Design without Compromise In all of circuit design, manufacturing and choices of components, researches are done to details to realize the vivid music reproduction without tonal coloration. At the same time, the stability in the long term is also considered. Best obtainable electrolytic capacitors, coupling film capacitors and winding resistors were chosen. Traditional hand-winded plastic bobbin-less interlaminar transformers were employed for the power transformer and choke coil. They are made by an orthodox lacquer vacuum impregnation method to minimize the v
