VM540ML Audio-Technica cartridge replacement for AT440MLa cartridge

VM540ML AUDIO-TECHNICA CREPLACEMENT FOR AUDIO-TECHNICA (AT-440MLA AT 440MLA) AT440MLA CARTRIDGE
- AT440's Provenance of Excellence: 2013, 2014, 2015, 2016, 2017, 2018 Editors Choice Award The Absolute Sound March Issue 231, 241, 251, 261, 271, 281.

With the formidable VM540ML phono cartridge, Audio-Technica has replaced and superseded—at a more affordable price—the highly regarded AT440's (retail: $390.00) musical excellence that rightfully should be compared with moving magnets costing up to $500. Yes, it is that good. The Audio-Technica VM5440ML's excellence lies in the suitable employment of advanced designs uniquely available to Audio-Technica because of its rich technical history and production capabilities:

● Audio-Technica's Vector-Aligned Dual Magnet design, which uses two tiny magnets to achieve ideal geometry and low magnet mass, for excellent channel separation and extended frequency response.

● The Audio-Technica VMN40ML's MicroLine stylus produces more accurately rendered high frequency response with less wear and distortion than elliptical or conventional linear contact styli. The small curving rate of the MicroLine stylus enables it to track and playback the inner part of the record groove that other styli can hardly maintain. Also the curving rate of the MicroLine stylus does not change until the stylus is almost worn unlike that of conventional styli which increases as they are used. Accordingly, the MicroLine stylus has a much longer average playing life. It plays better, longer.
