This Audio Research LS25 MKII tube preamplifier is a high-quality device that offers a number of audio inputs, including stereo L/R RCA and XLR inputs. With two channels, this preamplifier is perfect for enhancing your audio experience and delivering superior sound quality. The brand, Audio Research, is well-known for producing top-of-the-line audio equipment, and this model, LS 25 MKII, is no exception. Whether youre a music enthusiast or a professional audio engineer, this preamplifier is an excellent choice for amplifying your audio signals. Its perfect for use in a home audio setup or in a professional recording studio. So, if youre looking for a reliable and high-performance preamplifier, the Audio Research LS25 MKII is an excellent choice. This particular unit was re-tubed, serviced and all switches cleaned in Dec 2023. Since then, it has about 100 hours on the new tubes. I purchased an Audio Research Reference 5se, so I will no longer be using the LS 25 MKII. That is the only reason I am selling it. The unit has a broken screw head in the top panel (right rear). The included remote control battery back tab (not control) is broken. A small piece of tape or a drop of glue works perfectly to hold it in place (See Photos). Visually the unit shows like new and has very few imperfections. The photos do it no justice. Sonically it is perfect! The unit will be packaged in the original box. Comes with manual, power chord and remote control. You are going to love it!
