Its fully discrete circuit design avoids operational amplifiers for ultra-low noise performance and accurate RIAA equalization, resulting in clean, natural sound with lush mids — typically found in much larger and more expensive tube phono stages. Supporting both moving magnet (MM) and moving coil (MC) cartridges, Tube Box E features adjustable gain and loading options to match a wide range of cartridges. The front-panel subsonic filter and gain controls let you tailor performance on the fly, while replaceable 2 x ECC83 tubes offer the freedom to experiment with tube rolling and fine-tune your sound signature. Built in a rigid metal enclosure with beautifully machined aluminium controls and gold-plated RCA connectors, Tube Box E offers both reliability and elegance — available in classic black or silver finishes to fit any hi-fi system. \u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports MM \u0026amp;
