Reviewer’s Reactions to 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.





Michael Fremer titled his Phono 2-SB review “Affordable Excellence” and concluded that very positive review by saying, “So, is the LKV Phono 2-SB 'an overachiever and a ridiculously great value for the money'? In a word, 'Yes.'" Read more...

Harry Pearson describes the Phono 2-SB as “… a great phono stage at a quite reasonable price.” Originally published on HPSoundings.com. Read more...

Tom Lyle says that the Phono 2-SB is “… one of the best phono preamplifiers I've ever had the pleasure of using in my system.” Read more...

Scott Hull awarded the Phono 2-SB a Part Time Audiophile “Best of 2013” and more recently said that, “Overall, the 2-SB seems to fall on the warm-side of sonic neutrality, with excellent dynamics and detail retrieval. It is, in a word, excellent.” Read more... Also read "An Analog Twist: Bob’s Devices 1131 Step Up Transformer" using the 2-SB. Read more...

More about the LKV Phono 2-SB

The Phone 2-SB's 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.
