The Audio Research LS17 Tube Preamplifier is a high-quality audiophile preamp designed by Audio Research. This tube amplifier features two channels and comes in a sleek black color. Known as the Baby Ref, this preamplifier is ideal for enhancing the audio quality of your home audio system. With its tube technology and Audio Research's reputation for producing high-end audio equipment, the LS17 is sure to provide a superior listening experience for audiophiles. The preamp is in excellent physical and operational condition. The case and face are near mint. The top has a couple of linear marks that can’t be captured in the photos. They aren’t scratches, more like scuffs that can only be seen at certain angles with the light. It works perfectly. I don’t know how many hours are on the tubes. I purchased locally approximately 6 months ago while my SP16 was awaiting repair. I love the sound, but I do want to return to a built in phono input. This preamp is line stage only. Balanced inputs and outputs are nice to have as well for those that can use them. I do not have remote, manual, or original box. I will include a power cable. I will pack carefully and ship quickly. I think you’ll be very happy - it’s a beautiful preamp with great sound. Check all the rave reviews online.

These amplifiers are available with freight shipping available or for local pickup in Columbus, OH. Feel free to message me your shipping zip code for a freight quote. Do not miss the chance to own these amazing amplifiers at an incredible price.After two years in development, the new Reference 160M (REF160M) Monoblock Power Amplifier is built like no other, looks like no other, and sounds like no other amplifier that you have ever heard, but it is unmistakably Audio Research. It features a refined audio topology with fewer and better components in the signal-path than in previous designs, switchable Ultralinear/Triode operation, proprietary auto-bias, output tube monitoring and protection, an advanced power meter, and much more. This array of features has never been offered before in an Audio Research amplifier. The designers at Audio Research wanted to create a new style that would complement the look of the REF6 preamp while also featuring a transparent faceplate that allows a view of the glowing KT150 vacuum tubes. While this window allows you to see the output tubes, it also incorporates an innovative dual-layer construction with distinctively etched markings that create an integrated power meter. The power meter’s output-level markings illuminate via hidden LEDs, and the illumination brightness is adjustable. The REF160M includes a sculpted cover with an integrated fan to cool the heat generated by the four (4) KT150 output tubes and two (2) 6H30 driver tubes. Solid-state power regulation was chosen to provide increased efficiency, stability, and reliability. The power supply stage uses a newly developed High Energy Capacity Transformer and a hefty bulk storage-capacity network to provide extremely high current on demand for transient peaks and intense dynamics, as well as for prodigious bass depth and authority. It is understood that the best path is the shortest path. Audio Research engineers created a new audio circuit topology with the shortest signal path and the fewest components. Those components are not only the best available, many are custom made for Audio Research. Incorporating these quality components is a special 4-layer circuit board that lowers the noise floor to unprecedented levels, and a design which was previously reserved for use in our preamplifiers. The result is a new benchmark in musicality in every criterion of sound quality.The REF160M also features a proprietary auto-bias circuit that works with various tubes types, including 6550, KT88, and KT120, in addition to the supplied KT150 and works constantly to maintain precise bias of the output tubes, while also adjusting for tube wear. There is no need to check or adjust bias ever again.The new REF160M breaks new ground sonically, aesthetically and operationally, and will be available in Natural (Silver) or Black finishes.POWER OUTPUT140 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 140 watts, below 0.04% at 1 watt.
