United States of Analog | December 19, 2025
🎙️ Early Video Analysis
What is this video about?
This video is a review of the DS Audio DSE3 optical phono cartridge, which the host Bob describes as revolutionary. He’s doing a shorter format video (under 5 minutes) to demonstrate this unique cartridge system that uses optical technology rather than traditional magnetic pickups.
What gear, products, or brands are discussed?
- DS Audio DSE3 optical cartridge system – $3,000 for cartridge plus dedicated proprietary phono stage, uses LED lights, has cantilever and stylus like regular cartridge
- Cambridge Audio Alva ST turntable – has removable headshell, used for testing the cartridge (host notes it’s not necessarily price-appropriate pairing)
What are the host’s main opinions or takes so far?
- [00:01:13] Host describes the cartridge as “fantastic”
- [00:00:20] Initially disappointed it doesn’t use laser beam technology as he expected
- [00:00:56] Impressed by easy setup process, got it running “literally within minutes”
- [00:01:13] Had “a lot of fun” using it over three weeks of testing
Were there any funny moments, strong opinions, or memorable quotes?
- [00:00:20] “That’s what I initially thought, but to my chagrin, it did not use a laser beam” – host’s disappointment about the lack of laser technology
- [00:01:06] “Man, it lights up those grooves” – enthusiasm about the LED lighting effect
- [00:01:10] “No, it’s not reading the grooves. I think it’s pretty much just decorative” – clarification about the LED’s actual function
3-Paragraph Summary:
Host Bob introduces a special under-5-minute video reviewing the DS Audio DSE3 optical cartridge, emphasizing its revolutionary nature in the analog audio world. While initially disappointed that it doesn’t use laser beam technology as he expected, he’s intrigued by its LED lighting system and optical approach to audio pickup.
The cartridge system costs $3,000 and includes both the cartridge and a dedicated proprietary phono stage, making it a complete system. Despite being price-mismatched with his Cambridge Audio Alva ST turntable, Bob found the setup process remarkably easy thanks to the turntable’s removable headshell, getting everything operational within minutes.
After three weeks of testing, Bob has clearly enjoyed the experience and describes the cartridge as “fantastic.” The LED illumination of the record grooves appears to be decorative rather than functional, but adds to the unique character of this optical cartridge system. He prepares to explain in layman’s terms how this innovative technology actually works.
⏱️ Mid-Video Analysis
What gear, products, or brands are discussed in this portion?
- DS Audio DS-E3 optical cartridge [00:01:58]
- Moving magnet cartridges [00:01:24]
- Moving coil cartridges [00:01:43]
What are the host’s key findings, verdicts, or opinions?
- [00:02:43] The beryllium shade in the optical cartridge has much less mass than traditional coil/magnet systems, resulting in lower distortion and higher output
- [00:02:48] The reduced mass allows the stylus to track much better
- [00:03:00] Host noticed “fantastic separation” and extremely precise instrument placement that was “almost not to be believed”
What are the host’s key findings, verdicts, or opinions?
- [00:02:43] The optical cartridge produces lower distortion and higher output compared to traditional designs
- [00:02:48] Better stylus tracking due to reduced mass
- [00:03:00] Exceptional stereo separation and instrument placement precision
Any audiophile tips, advice, or how-to content?
- [00:01:24] Technical explanation of how moving magnet cartridges work (magnet moves between coils)
- [00:01:43] Technical explanation of moving coil cartridges (coil moves between magnets)
- [00:01:58] Detailed explanation of optical cartridge technology using LED light, photo sensor, and lightweight beryllium shade
Any memorable quotes or strong takes?
- [00:03:03] “the placement of instruments was so precise, it was almost not to be believed”
Summary:
This portion of the video provides a technical deep-dive into different cartridge technologies, starting with explanations of traditional moving magnet and moving coil designs. The host explains how moving magnet cartridges work with a magnet at the cantilever end moving between coils, while moving coil cartridges reverse this setup with a coil moving between magnets.
The focus then shifts to the revolutionary optical technology of the DS Audio DS-E3. The host describes how this system uses an LED light projecting to a photo sensor (like a digital camera), with a lightweight beryllium shade attached to the cantilever that modulates the light to create the audio signal. This design eliminates the relatively heavy coils and magnets found in traditional cartridges.
The host emphasizes the significant advantages of this reduced mass, explaining that it results in lower distortion, higher output, and better stylus tracking. From his listening experience, he reports exceptional stereo separation and instrument placement that was so precise it was “almost not to be believed,” suggesting this optical technology represents a major advancement in cartridge design.
🏁 Final Thoughts & Verdict
What gear, products, or brands are discussed in this final portion?
- DS Audio DS-E3 optical phono cartridge [00:04:42]
- Moving magnet cartridges (comparison) [00:03:13]
- Moving coil cartridges (comparison) [00:03:29]
- Wax-wing phono stage [00:04:21]
What is the host’s final verdict or conclusion?
[00:04:50] The host concludes the DS-E3 is “$3,000 for the system. Easy to set up, super satisfying to watch, super satisfying to listen to.” He describes it as providing a “completely different experience” compared to moving magnet cartridges with “transparent, clear, precise instrument placement, large soundstage, wide soundstage” [00:03:20-00:03:29].
Any final tips, caveats, or advice for viewers?
- [00:03:46] The elliptical stylus will wear over time and will need factory replacement
- [00:04:05] The cartridge doesn’t reduce pops and clicks from vinyl records
- [00:04:21] For noise reduction technology, viewers may need to consider a “wax-wing phono stage”
- [00:04:28] Clarifies that it’s not using lasers or light beams on the grooves to extract sound
How did the video wrap up?
[00:04:55] The host wrapped up with his standard channel sign-off: “We’ll see you next time here in United States of Analog. Cheers.”
Any memorable closing quotes or strong final opinions?
[00:04:37] “But it does make a lot of sense when you think about it. Low mass equals low noise, higher output, better tracking.”
[00:04:50] “Easy to set up, super satisfying to watch, super satisfying to listen to.”
Summary
In this final portion, the host delivers his verdict on the DS Audio DS-E3 optical phono cartridge, emphasizing its superior performance compared to moving magnet cartridges. He highlights its transparent sound, precise instrument placement, wide soundstage, and notably higher output than typical moving coil cartridges. The visual appeal of the green LED and the listening experience both impressed him significantly.
However, he addresses some limitations and clarifies expectations. The cartridge still uses a traditional elliptical stylus that will wear over time, and contrary to his initial hopes, it doesn’t reduce the pops and clicks inherent in vinyl playback. He explains that for noise reduction technology, viewers would need to look at specialized phono stages instead, and clarifies that this isn’t a laser-based system reading grooves optically.
The host concludes with strong enthusiasm for the $3,000 system, praising its ease of setup and dual appeal as both an engaging visual and auditory experience. He summarizes the core benefits as “low mass equals low noise, higher output, better tracking,” positioning the DS-E3 as a compelling option in the high-end cartridge market before ending with his standard channel sign-off.
