A great-sounding, ALL-TUBE, line-level preamplifier, the Jumbo Shrimp is very quick and lively sounding. Its transparent presentation will bring out new details from your favorite recordings. Direct-coupled, non-inverting, two-tube gain stage uses 2 x 12AT7 and 2 x 7044. The quality of parts used, such as the MIT/MultiCap polypropylene capacitors and cool backlit logo are simply not found in other components at this price level. In addition to the Remora Remote control system, an additional White Follower buffer stage was engineered into the Jumbo Shrimp to better drive the volume control. This fortunately resulted in greatly increased headroom and significantly reduced distortion in the whole unit. It is a big improvement besides being convenient. TAS Review At Manley Labs being shrimp-like is a good thing, as it means a smaller, less painful price. The Manley Shrimp is anything but small, however, when it comes to aesthetics, parts- and build-quality, and what matters most, great sound."
Features:
  • Very short, simple minimalist signal path. All-tube design. 2 x 12AT7 input, 2 x 5670 driver, and 2 x 7044 output.
  • Signal path furnishes very high dynamic range with prodigious input and output signal headroom.
  • Signal path also delivers high bandwidth, low noise, modest local negative feedback and low distortion, and is voiced for best musical performance.
  • Radio-Frequency based remote command of the silicon-free high-quality motorized VOLUME attenuator set, for infinitely resolvable control of listening levels. No need to "point" the remote in any direction. Now the Shrimp's attenuator set can be controlled from another nearby room, through walls, floors and doors, and through opaque equipment closet or cabinet doors too!
  • Dedicated White Follower stage using the 5670 dual triodes effortlessly drives all passive interstage circuits; volume, balance and output stages receive crisp instruction from the Follower regardless of control settings.
  • Generous energy storage via large power supply capacitors for more impact in the bass.
  • No global feedback makes the Shrimp very fast sounding.
  • Non-inverting two-triode gain stage is direct-coupled for most pure signal path.
  • Cool White-follower output stage provides low 50 Ohm output impedance. This is much better than a boring plain ol' cathode follower. The Shrimp can drive anything, not to worry.
  • Filament supply floated 80V above chassis ground for quieter operation and longer tube life.
  • ALPS audiophile-grade balance and motorized VOLUME pots. We use the nice parts in here!
  • MIT/MultiCap polypropylene audiophile-grade signal coupling capacitors, including two 30 uF monsters on the output stages.
  • Warm-up delay / MUTE button. Features and quality components usually not found on entry-level pieces.

    I wish I knew how to describe things better, but I have been listening this for about 2 hours now. Sound is just fantastic. I am hearing instruments pop out that I had not noticed before. There is just more of everything. I love it!
