I've used Audioengine powered speakers on our desktop computer systems for a long time. The pair in front of me at the moment, A5s, were purchased in 2013, and have been reliable in daily use since then. Combined with an SVS SB1000 sub, carefully matched, the system sounds very good. Not as good as the Revel Salon2/Velodyne DD18Plus main system, but pretty darn good. The AE A2+ speakers in another more space limited desktop system do a great job considering their diminutive size. The A5+ was reviewed by Amir, and they did pretty well. I've been on Audioengine's email marketing list for all these years, and sometimes I read them. In this most recent email though, they really got me laughing. Maybe it will for you:


Why Analog Amplifiers Are Essential for Vinyl Enthusiasts

Introduction

Vinyl records have experienced a remarkable resurgence in recent years, captivating music lovers with their warm and authentic sound. For true audiophiles, the appeal of vinyl lies in its ability to reproduce music with unparalleled richness and depth. However, this authenticity can be compromised by the choice of speakers and amplifiers.

Why Do Audiophiles Prefer Analog Amplifiers for Turntables?

Vinyl records are beloved for their analog warmth and depth, offering a listening experience that's as authentic as it gets. Analog connections, like AUX or RCA, are the preferred choice of audiophiles because they maintain the integrity of the sound without introducing digital compression. Bluetooth technology, even with advancements like aptX HD and aptX Adaptive, compresses audio data, potentially losing some of the nuanced details that vinyl enthusiasts love. This compression can strip away the warmth and richness that make vinyl records unique, similar to the effect of digital amplifiers.

Many audiophiles prefer the purity of an analog signal path, directly from the turntable to the speakers, ensuring an unaltered connection without digital interference. This approach guarantees a true connection to the music, capturing every detail and emotion as intended by the original artists.

In this article, we explore why analog amplifiers, such as Class AB amplifiers, are essential for preserving the integrity of vinyl records, and why digital amplifiers often fall short.

The Beauty of Analog Sound

Vinyl records are analog by nature, capturing the nuances of music that digital formats often miss. When music is recorded onto vinyl, a cutting stylus etches grooves into a master disc, creating a continuous physical representation of the sound waves. These grooves correspond to the sound's frequency and amplitude, directly translating the original audio into a physical format. When played back, a needle, or stylus, moves along these grooves, vibrating to reproduce the sound waves, preserving every detail of the recording.

Analog sound means that the audio signal is a continuous wave that directly mirrors the original sound waves. This process preserves the full range of audio frequencies and the subtle variations in the music, offering a warm and rich listening experience. Vinyl enthusiasts prefer this format because it delivers music with all its original depth and character.

In contrast, digital formats convert sound into binary code, which consists of a series of zeros and ones. This conversion process, known as sampling, takes snapshots of the audio signal at discrete intervals, typically thousands of times per second (for example, 44,100 times per second for CD-quality audio). While this sampling rate is high, it still only approximates the original sound wave. Some nuances and subtle details can be lost in this process, leading to a less authentic reproduction of the music.

The true essence of vinyl can be compromised when played through speakers with digital amplifiers. Digital amplifiers first convert the analog audio signal from the vinyl into a digital format for amplification and then back to analog for playback. This conversion process can introduce digital noise, distortion, and a loss of audio fidelity, undermining the benefits of the analog format. This is why preserving the analog signal path, from the turntable to the speakers, is crucial for vinyl enthusiasts who seek the most authentic listening experience.

Why Digital Amplifiers Fall Short

Digital amplifiers are popular in many modern speakers due to their efficiency and compact size. However, they prioritize cost-saving measures over audio quality, making them less than ideal for vinyl playback. Here's why:

  • Conversion Losses: Digital amplifiers convert the analog signal from a vinyl record into a digital format, which can result in loss of detail and audio fidelity. The reconversion back to analog may not accurately reproduce the original sound.
  • Digital Noise: The digital processing involved in Class D amplifiers can introduce unwanted noise and distortion, affecting the clarity and warmth that vinyl is known for.
  • Budget Constraints: Many digital amplifiers are used in speakers designed to meet budget constraints, often sacrificing sound quality to keep prices low. This can lead to a compromised listening experience.
For vinyl enthusiasts who appreciate the analog sound's warmth and detail, these drawbacks are significant. The choice of amplifier can make or break the listening experience, and that's where analog amplifiers, such as Class AB amplifiers, shine.

The Superiority of Analog Amplifiers

Analog amplifiers, like Class AB, are designed to preserve the authentic sound of vinyl records. They combine the strengths of Class A and Class B amplifiers, delivering high-fidelity audio with minimal distortion.

Here's why Audioengine Home Music Systems, which feature analog amplifiers, are the preferred choice for many vinyl lovers:

  • True Analog Sound: Class AB amplifiers handle audio in its original analog form without converting it into digital signals. This maintains the richness and detail of the music, allowing you to hear every nuance as the artist intended.
  • Smoother Sound: The design of Class AB amplifiers provides a smoother and more detailed sound, capturing the essence of the music. This results in a listening experience that is both engaging and authentic.
  • Dynamic Range: Analog amplifiers offer a dynamic range that captures the full spectrum of sound, from the deepest bass to the highest treble, ensuring that nothing is lost in translation.
  • Quality Craftsmanship: Speakers with analog amplifiers often prioritize quality materials and craftsmanship, resulting in superior sound quality and durability.
Choosing the Right Equipment

When it comes to enjoying vinyl records, choosing the right speakers and amplifiers is crucial. For those who value authenticity and depth in their music, investing in speakers with analog amplifiers is a decision that pays off in spades.

Analog amplifiers preserve the essence of vinyl, delivering a listening experience that digital amplifiers simply cannot match. Whether you're a seasoned audiophile or a newcomer to the world of vinyl, the choice of equipment plays a significant role in the enjoyment of your music.

Conclusion

If you cherish the authentic sound of vinyl records, don't let digital amplifiers compromise your listening experience. Analog amplifiers, like Class AB, provide the fidelity and richness that vinyl enthusiasts crave. Just as you wouldn't listen to vinyl with Bluetooth earbuds, opting for speakers with analog amplifiers ensures that you hear your favorite records as they were meant to be heard.

Explore the world of analog sound and discover the joy of music in its purest form. Embrace the warmth, detail, and depth that only analog amplifiers can deliver, and elevate your vinyl listening experience to new heights.
 
This looks like it was written by an undergrad who used AI.
I had the same exact thought.

This is what happens when you fire or lose the old marketing person who knows audio and hire someone green who just craps things out of ChatGPT.

Pretty gross and lame. Audioengine, shame on you.
 
Sometimes the marketing department does not talk to the engineering department.
You are assuming good faith... there is none
B.S. and they know it
Best way to describe this Audioengine drivels and pack of lies: "anything for a buck"

Peace.
 
It's blatant slagging of class D amplification. What a load of drivel and rubbish
Yet the newest iteration of their N22 amp is chip based TDA 7492. Not exactly cutting edge stuff. You can get these modules on Aliexpress for a few dollars apiece. Isn’t this basically a DIY board?
 
My favorite part is where it says:

This conversion process, known as sampling, takes snapshots of the audio signal at discrete intervals, typically thousands of times per second (for example, 44,100 times per second for CD-quality audio). While this sampling rate is high, it still only approximates the original sound wave. Some nuances and subtle details can be lost in this process, leading to a less authentic reproduction of the music.

Apparently Nyquist-Shannon sampling theory eludes Audioengine. I've tried to imagine how embarrassed their engineers are when they read this nonsense. It is cringeworthy.

As for the "digital amplifier" reference, even Audio Precision has made that mistake on their website. If you search for "digital amplifiers", you'll get hundreds of links.

Edit: Audio Precision still has the article I was referencing on their web site:

These speakers remind me of a powered set sold by U-Turn, the maker of turntables in Boston. U-Turn emphasizes the Class AB amps built into their desktop speakers as points of differentiation with most other makers. As a fan of the Fosi TPA3255-based amps I don't see the appeal but there you have it.
 
If I only had the business/marketing chops to sell a snake-oil disguised as a blanket.
Yeah: A blanket!
Replace blanket in place of the word 'vinyl' and see if it has potential.
