The Shrimp Preamplifier Features: Very short, simple minimalist signal path. All-tube design. 2 x 12AT7 + 2 x 7044 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-tube 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. NOBLE audiophile-grade level and balance 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. Read the Owner's Manual
