    Stereophile LogoBenchmark AHB2 Power Amplifier

    AHB2 - Receives Stereophile's Highest "A" Rating for Power Amplifiers

    "Benchmark's AHB2 makes use of THX Corporation's Achromatic Audio Amplifier (AAA) technology, in which a low-power feed-forward amplifier drives a low-bias class-AB output section."

    - Stereophile, 2023

    "Much more apparent low-level detail in already-familiar recordings" - Kalman Rubinson

    "A tonal balance that sounded more 'right' than any of [the other amps on hand]." - Kalman Rubinson

    "An extraordinary amplifier." - John Atkinson

    Benchmark LA4 Silver

    LA4 - Receives Stereophile's Highest "Class A" Rating for Preamplifiers

    "Benchmark's usual approach to design is to out-spec the competition, and so it is here. Like other Benchmark equipment he has tested, the affordable LA4 challenged the resolution of John Atkinson's test instruments, with 'superb' channel separation, 'extremely low noise, and virtually no power-supply-related spuriae.'"

    "Benchmark's LA4 is the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I have encountered." - John Atkinson

    "In his listening room, Kalman Rubinson compared the LA4 to a cable—and couldn't hear any difference. He concludes, 'the LA4 is probably the most transparent and revealing audio component I've ever used. It does not seem to leave any fingerprints on the sound.'"

    DAC3 - Class A+ Recommended Processor - Stereophile

    Benchmark DAC3

    DAC3 HGC, DAC3 B - Receive Stereophile's Highest "Class A+" Rating

    "The DAC3 B is a stripped- down, lower-priced version of the DAC3 HGC, which omits the headphone amplifier, balanced and unbalanced analog inputs, volume, mute, and polarity controls." - Stereophile

    "The DAC3 was all about depths, in several respects...I heard deeper into the music."

    "All I can say is Wow!"

    - John Atkinson

    "In a Follow-Up, JCA wrote of using the Benchmark processor with the same company's AHB2 power amp—a combination of high source output voltage and modest amplifier gain that he describes as 'optimal for minimizing noise and distortion' —and reported hearing 'richer and more interesting' reproduction of very subtle details."

    Making Sound with Plasma - Hill Plasmatronics Tweeter

    by John Siau June 06, 2023 2 min read

    At the 2023 AXPONA show in Chicago, I had the opportunity to see and hear the Hill Plasmatronics tweeter. I also had the great pleasure of meeting Dr. Alan Hill, the physicist who invented this unique device.

    The plasma driver has no moving parts and no diaphragm. Sound is emitted directly from the thermal expansion and contraction of an electrically sustained plasma. The plasma is generated within a stream of helium gas. In the demonstration, there was a large helium tank on the floor with a sufficient supply for several hours of listening.

    While a tank of helium, tubing, high voltage power supplies, and the smell of smoke may not be appropriate for every living room, this was absolutely the best thing I experienced at the show!

    System Performance Calculations

    by John Siau June 03, 2023 13 min read

    If an audio system is composed of multiple components, we may have detailed specifications for each component, but we will not know the performance of the combined system without doing some calculations. You may have questions such as these:

    • Will my audio system produce audible noise?
    • Will my audio system produce audible distortion?
    • How will my audio components work together as a system?
    • How loud will my audio system play?

    Use Benchmark's online audio calculators to find answers!

    For example, if we know the output power of an amplifier, as well as the sensitivity and impedance of our loudspeakers, we can calculate the maximum sound pressure level that our system can produce.
