Manley Laboratories Jumbo Shrimp Preamplifier Black

The Manley Jumbo Shrimp Preamplifier delivers wide bandwidth, exceptional signal-to-noise performance, and substantial output drive capability through a direct-coupled, all-tube signal path. Hand-assembled in California with audiophile-grade components including MIT/MultiCap polypropylene coupling capacitors, this preamplifier demonstrates that sonic excellence is achieved through circuit simplicity and precision engineering rather than complexity.

Direct-coupled topology with zero global feedback
The Jumbo Shrimp employs a non-inverting two-triode gain stage in direct-coupled configuration, eliminating interstage coupling capacitors for maximum signal purity. Engineered with minimal local negative feedback and zero global feedback, the circuit achieves exceptional transient accuracy and dynamic linearity. High input and output signal headroom ensures the preamplifier maintains transparency across all operating levels, preventing sonic bottlenecks within the signal chain.

White Follower drive stage with exceptional load capability
A dedicated White Follower output stage utilizing 5670 dual triodes provides robust drive capability for all downstream components and passive networks. Combined with 50 Ohm output impedance, the preamplifier delivers stable performance into complex loads and extended cable runs to any power amplifier configuration. Substantial power supply capacitance ensures dynamic authority and low-frequency extension across demanding program material.

Wireless remote operation with precision volume control
An RF remote control system enables seamless operation of the motorized ALPS volume attenuator through walls and enclosed cabinetry without line-of-sight limitations. All signal path components meet audiophile specifications, including MIT/MultiCap polypropylene film capacitors for coupling applications. The Jumbo Shrimp embodies Manley's commitment to uncompromising sonic performance through refined circuit topology and premium component selection.
