Audio Research - LS-3 (PRE-ORDER) 2-Channel Solid State Preamplifier The LS-3 is an exciting new preamplifier that showcases the innovative work of our dedicated team of solid-state engineers. While it may appear externally identical to the LS-2, the LS-3 represents a significant advancement in solid-state design and technology.At its core, the LS-3 utilizes a differential JFET-based input stage, which enhances signal integrity and reduces noise, followed by a bipolar transistor-based voltage amplifier that ensures robust performance. The Class-A output stage delivers a warm and dynamic sound, making it a perfect choice for discerning audiophiles. The signal path in the LS-3 is meticulously designed with dual mono architecture, featuring separate power transformers for each channel. This configuration not only enhances channel separation but also contributes to a cleaner, more immersive listening experience. Additionally, the inclusion of a zero gain cascaded voltage reference and linear power supplies ensures optimal stability and performance. With the LS-3, Audio Research continues to push the boundaries of high-fidelity audio, delivering a preamplifier that combines cutting-edge technology with the passion for sound quality that has defined our legacy. This remarkable piece of equipment is set to elevate your audio experience to new heights. Feature Set Includes: • Full touch screen display, including balance, input labeling, and display options including color.• New machined metal remote.• Balanced XLR and RCA inputs.• Optional DAC card including USB, Coax and Optical. User installable.• Optional MM/MC Phono card. User installable.• US Retail $7,450. Adding the DAC or Phono Card adds $1,000 each, or $1,500 for both cards installed in a new LS-3 preamp.
