  BP-320 All-FET MM/MC Phono Preamplifier

BP-320 is a MM/MC phono preamplifier. This is the top-of-the-line phono preamp. The PCB layout incorporates features such as ground plane, MC loading switch, and RIAA options.
BP-320 is one of the best phono preamps money can buy.

Highlights :

• Only JFETs are used in input and VAS stages to achieve very low
noise and high-resolution amplification. High current biased
MOSFET output stages ensure low output impedance and
drivability.
• Very low noise.
• Gain settable for 44dB (MM), 54dB, and 64dB (MC).
• Hybrid (passive-active combination) and all-passive RIAA
equalization are supported.
• MC pickup loading selectable by an on-board 6-position switch
• Configurable for balanced operation
