Experience high-fidelity audio with the Jumbo Shrimp Preamplifier, designed for audiophiles who demand superior sound quality and convenience. This preamplifier features a minimalist signal path for exceptional dynamic range, high bandwidth, low noise, and low distortion, ensuring a clean and musical performance.


Key Features:

  • Minimalist Signal Path: Short and simple design focuses on high dynamic range and prodigious output drive capability.
  • Tube Design: All-tube configuration includes 2 x 12AT7 input tubes, 2 x 5670 driver tubes, and 2 x 7044 output tubes.
  • White Follower Stage: Utilizes 5670 dual triodes to drive the passive interstage volume control, providing crisp, transparent audio with excellent rhythm and extension.
  • Remote Control: RF Remora Remote allows you to control the volume from anywhere, even through walls and doors.


Design and Performance:

The Jumbo Shrimp's signal path delivers high dynamic range with ample input and output headroom. It maintains high bandwidth and low noise, using modest local negative feedback and low distortion to achieve the best musical performance. The dedicated White Follower stage ensures the passive volume, balance, and output stages receive precise control, regardless of settings. The result is a fast, responsive sound with impressive impact, especially in the bass.


Quality Components:

This preamplifier includes ALPS audiophile-grade balance and motorized volume pots, along with MIT/MultiCap polypropylene signal coupling capacitors. Large power supply capacitors provide generous energy storage for more impactful bass. The filament supply is floated 80V above chassis ground for quieter operation and longer tube life.
