About the L30
The TOPPING L30 is a compact, single-ended desktop headphone amplifier that can also operate as a variable-output preamplifier. It uses TOPPING’s Nested Feedback Composite Amplifier (NFCA) design and offers three gain settings for use with sensitive in-ear monitors and more demanding headphones. It has RCA analog inputs, variable RCA outputs, and a 6.35 mm headphone output. This is the original L30, not the later L30 II.
