New Angled, Single Layer Headbasket -

The MJE mods for your v250 start with a new single-layer, angled headbasket. The stock, two-layer cylindrical headbasket is ridden with standing wave coloration. The new, replacement headbasket increases open area to reduce internal reflections and coloration. You’ll hear clearer, less “boxy” and more detailed sound with more accurate transient response – hallmarks of the classic AKG C12 – itself a single layer headbasket design.

MJE-K47 Capsule Upgrade -

Classic sound is within reach. Next, my MJE-K47 capsule delivers the same frequency response as an actual Neumann K47 capsule. You'll enjoy the classic mid-focused punch of the K47 design with its natural-sounding top. This MJE-K47 capsule has greater sensitivity and output than the stock small diaphragm capsule installed in the v250 and that means you'll hear better-than-stock signal to performance.

Premium Electronics Upgrades -

The circuit used in the v250 is a close approximation of a classic Schoeps transformerless design. However, the manufacturer used inexpensive poor-sounding, under-sized capacitors to save on parts costs. MJE attacks these compromises by substituting my field proven Premium Electronics upgrade. These component and topology upgrades improve bass response and reduce mid-to-high frequency distortion while providing a smoother top end.
