ADC ALT-1
Low cost version of the LMF-1 tonearm. Comes fitted with an aluminium arm tube (instead of carbon fibre) and detachable headshell.
Description
The optional stabiliser base ASL-1 provides additional mass to help stabilise lightweight turntable bases, thus establishing a firm foundation for mounting the ALT-1 arm.
The ASL-1 replaces the nut normally used to secure the arm to the turntable base.
Special lead wires (CD4W) are required for CD-4 systems. They are also useful to audiophiles whose preamplifiers have a large input capacitance.
The removable head (LMH-1) allows the audiophile whose tastes require alternative phono cartridges to make premounted changes in seconds.

Review
A low cost tonearm sourced in Japan. Of about 8.5g effective mass, it will suit most medium compliance cartridges, but does not give a good sound by modern standards. Failings include a treble brashness or brittleness and lack of stereo precision, not helped by slack bearing adjustment - £44 HiFi Choice 1984
