The LKV Mission
LKV Research offers music lovers great sounding audio preamps and amps at affordable prices. We focus on the characteristics of each component that truly matter for sound quality and use good engineering design and extensive listening to achieve excellent performance without incurring unnecessary cost.
Science and Art in the Service of Good Sound.
At LKV we believe that designing excellent audio components involves three fundamental steps: (1) identifying the necessary characteristics or elements necessary for the device in question to perform well; (2) applying sound engineering principles and techniques..
Welcome to LKV Research - The LKV Phono 2-SB
The 2-SB is LKV’s state of the art phono preamplifier, designed to enable your system to convey to your ears the emotion, drama and beauty of the music on analog LP recordings. It has every element needed to amplify and equalize with great fidelity the minute voltages produced by the cartridge as it traces the grooves on your vinyl records.
Harry Pearson, of HPSoundings.com, preview describes LKV’s Phono 2-SB as, “a home run … a great phono stage, at a quite reasonable price (given the cost of such), but most of all, its sly way of getting inside the soul of the music itself.” Click here for additional reviews and press comments.
Tom Lyle, of Enjoythemusic.com says, the Phono 2-SB is “… one of the best phono preamplifiers I've ever had the pleasure of using in my system. I could imagine owner Bill Hutchins having to deal with backorders in the near future, because when word gets out that he is selling such a great product for such a reasonable price, the LKV Research is likely to become a very popular product... and for good reason! I highly recommend ordering one of these babies now, before everyone else gets the same idea.” Click here for additional reviews and press comments.
Very low noise and distortion allows all of the low level detail and subtle information encoded on the LP to flow to the rest of your system and to your ears. This information conveys much of the meaning and emotion of the music and contributes to creating a believable soundstage and solid, palpable images. The 2-SB achieves these very low levels of noise and distortion through good design:
- Multiple stages of power supply noise control using resistor/capacitor filters, capacitance multipliers and modern IC regulators to create very smooth, quiet power rails.
- Ultra low noise active components (jfets and bipolar transistors) biased into their quietest operating ranges.
- Cascode amplification circuits and active current sources to assure low distortion in each amplification stage.
- Differential (balanced) amplifier circuits to block incoming noise.
- Signal path capacitors using accurate polypropylene dielectric to pass the musical signal without smearing.
- Four-layer circuit boards to keep signal paths short and improve grounding.
- Three grounding options to minimize noise and avoid ground loop hum in a variety of systems.

LKV Line Stage Preamp First Prototype.
Chief Designer Bill Hutchins has completed the first prototype of LKV's second product, a line stage preamplifier tentatively designated the Line 2-SB. It is an all-out effort, designed to complement its older sibling the Phono 2-SB. Together they will deliver state of the art reproduction of recorded music.
EVENTS: LKV Research will be demonstrating its state of the art phono stage, the Phono 2-SB, at two audiophile shows this spring and summer.
May 31-June 2, 2013
The Home Entertainment Show in Newport Beach, California.
