Reduced in February 2024. Was: €3.250. The LS27 is a pure class-A design with zero feedback and a fully regulated power supply. The internal circuitry and connections are differentially balanced. Gain is provided by a hybrid audio circuit that includes JFET transistors and two 6H30 triode tubes. Multiple circuit changes and refinements account for greatly improved performance, including bulk power-supply storage that has been substantially increased, a new power transformer, and costly new output and bypass coupling capacitors that bring new dynamic life and even more refinement to the presentation.
Via only the remote, you can adjust the LS27’s display to one of nine brightness levels, adjust the levels of the left and right channels, keep track of how many hours the tubes have been used, adjust the gain for each of the six pairs of discrete inputs (high, medium, low), and invert the absolute phase of the output signal. The LS27 also includes a processor pass-through for home-theater use. A new microprocessor controls all functions. It has an ability to disappear in the way all good preamps are supposed to do, and does so with outstanding image size and width. It also combines great resolving power with a tonal richness, purity, naturalness and superb Bass impact and control. Specifications: Frequency Response: +0-3dB, 0.2Hz to 160kHz at rated output (Balanced, 200k ohms load). Distortion: Less than .01% at 2V RMS BAL output. Gain: Main output: Selectable for each input: 24dB, 18dB,
12dB Balanced output. (18dB, 12dB, 6dB SE output). Input Impedance: 120K ohms Balanced, 60K ohms SE. Inputs (8): Tuner, Phono, CD, Video, Aux 1, Aux 2, Monitor, Processor (XLR and RCA connectors). Output Impedance: 700 ohms Balanced, 350 ohms SE Main (2), 20K ohms minimum load and 2000pF maximum capacitance. Outputs (3): 2 x Main, 1 x Record (XLR and RCA connectors). Output Polarity: Non-inverting.
