Krell 300p Phono PREAMPLIFIER: Unleashing the True Essence of Vinyl

Product Overview

The Krell K-300p is a high-performance phono preamplifier designed for audiophiles who use both moving coil (MC) and moving magnet (MM) phono cartridges. It provides an optimal interface for each cartridge type with separate inputs and extensive adjustability, ensuring superior sound quality and flexibility. This preamplifier is ideal for those seeking to enhance their vinyl listening experience with precise control and high fidelity.

Key Features

Separate MC and MM Inputs: Allows for optimized performance with both moving coil and moving magnet cartridges.

  1. Adjustable Loading and Gain: Offers adjustable resistive loading from 10 to 47k ohms for MC inputs and capacitive loading from 10 to 680 pF for MM inputs. Gain is adjustable up to 62 dB for MC and 36 dB for MM.

  2. Selectable Infrasonic Filter: A 14 Hz high-pass filter can be engaged to eliminate low-frequency noise and acoustic feedback.

  3. Selectable Absolute Phase: Allows correction for recordings that may be phase-inverted.

  4. Easy Setup and Operation: All adjustments are accessible on the rear panel, and MC/MM selection is available on the front panel.

From the opening track the K300p lets it all happen

One of my most treasured albums is the clear vinyl 45rpm John Coltrane Blue Train from Classic Records. This fantastic pressing gives the incredible music its due. "Blue Train," the K300p allows the bouncy swagger of all involved to carry the music down the tracks with great forward momentum.
