Some very nice features on a vintage IA that can be had for US $200 or less.
MC sensitivity to 0.16 microvolts, and impedance loading choices on both phono circuits. Will handle almost all cartridges with ease, lots of flexibility.
5 watts of pure Class A power, especially nice for headphone use.
Plenty of power at 125 wpc for even the most maniacal of hard rockers. Will easily drive power-hungry speakers.
The variable loudness and eq controls are excellent and useful for dialing-in frequency response from even the most difficult masterings.
