DESCRIPTION
The Ray Tubes RESERVE 300B is the pinnacle of classic audiophile vacuum tubes, meticulously hand-selected and crafted for deep musical expression.

The RESERVE 300B’s legendary design offers warm, elastic bass, delicate and layered midrange, clear and smooth highs, and a wide, well-defined soundstage with excellent spatial clarity.
