I now have an abundance of redundant MC and MM cartridges. I simply could never go back after hearing the E1. I have just ordered the 003 for the main system which means that the E1 will soon go into the other room and subsequently elevate that system considerably. This is, quite simply “future analogue” at its best.

 by Bob Matthews on 

Having used numerous MM and MC cartridges with various phono stages, I was becoming more disappointed with analogue replay. As I spent more money on better but lower output MC cartridges and more sensitive phono amplifiers, I liked the improved sound quality but I was noticing an increased level of low level hum and general grunge or noise. This was really spoiling my enjoyment. Moving to the DS-E1 was a revelation, not only is the sound quality completely natural but all the noise has gone. The sound now comes from an inky black background. This is wonderful and I can't stop my foot from tapping! Thank you Guilford Audio for introducing me to this cartridge and equaliser and thank you DS Audio for a fantastic product.

DS-E1 set

DS-E1 Happy days with music I used to listen to it with DENON's station blur, so I used many types of MC, including the genuine DL-103. Since the DN-308F is equipped with an equalizer amplifier, there was no need to prepare an equalizer amplifier or preamplifier. MC listening with the equalizer of DN-308F is fun with this, but I still feel the age. Recently, I considered the introduction of DS-E1 on the occasion of converting SAEC's 407/23 to a pure straight titanium pipe. If you borrow an E1 listening device and listen to it, it will listen to only music while being more neutral than any cartridge you have ever heard. You have to be prepared for a considerable expense when upgrading the MC and phono equalizer amplifier, but the DS-E1 is a set of cartridge and equalizer, and this price is really surprising. It is difficult to make the sound into letters, but in the low range, the resolution or subduction is drawn properly, and when you listen to Bronberg's bass, you can understand the fingering and scale firmly rather than letting it be heard in the atmosphere. The drum solo at MJQ's pit-in live Rosary, and the repeated hits of tamtam, bass drum, and bass drum do not... view more

Stereophile DS003 review

“DS Audio’s DS003 photo-optical cartridge with the matching energizer delivered the complete menu of elite cartridge perks including super-silky silences, taut, tuneful, textured bass, and a vivid, Leica focused midrange that no digital source could hope to match. Sincerely recommended.” Herb Reichert, Stereophile November 2021

Hi Fi News review

“The DS 003 shows emphatically how trickle-down technology benefits the customer, while maintain a pecking order. As close as it is to the mind-boggling Grand Master, enough differences ensure that the two can co-exist: the DS 003 is the more lively of the two, the Grand Master the more subtle. That said, if you can afford a Grand Master, buy it. If you cannot, the astonishing DS 003 will still blow your mind”

Grand Master Cartridge Wins Two Golden EAR Awards!

“As I just said, the DS Audio Grand Master optical transducer comes closer to the sound of R2R tape than any other phono cartridge on the
market.A Grand Master-piece” Jonathan Valin “It would be hard to think of anything grander, at least when it comes to LP reproduction, than the new DS Audio Grand Master. This superlative device truly represents a revolution in analog playback, liberating LPs, as far as possible, from any residual dynamic constraints to strut their stuff. ” Jacob Heilbrunn


2021/7/9  Grand Master review by absolute sound

“Ken Kessler said something he seldom says about products under re- view. To wit, this is possibly the best cartridge he’s ever heard.
I hate to be a copycat, but…ditto.”

“The Grand Master is so truly supreme in resolution, transparency, spatial recreation, neutrality and any other parameter I can name that it’s impossible for me not say what I usually try to avoid: ‘This may be the best cartridge I’ve ever heard.’”  Ken Kessler Hi Fi News 2021

2021/1/6 New DS-E1 review is released 









“if you value sonic purity, supple textures, commanding bass reach, and impressive dynamic scaling, the DS-E1 will almost certainly tickle your fancy. Its transient fidelity, almost unparalleled quietude, and superb retrieval of low-level musical detail won me over. As I shared with Garth Leerer in a recent email, I am keeping the DS-E1 as my new reference. It represents shockingly good value in a world where five-figure cartridges no longer shock, and it sounds great.” All review is here.








“The Master1 cartridge and Master1 equalizer are simply outstanding components, setting new benchmarks for vinyl playback in several areas (mechanical silence, neutral voicing, and midrange-to-midbass realism).” – Jonathan Valin (The Absolute Sound)  All review is here

2020/6/28 New ION-001 Vinyl ionizer review is released
“I can report with complete confidence that the Vinyl Ionizer ION-001 is without a doubt the most effective anti-static device I have ever used. My vinyl playback has never sounded quieter, more revealing, and more enjoyable.”

2020/4/22 New DS-E1 reviews are released(Taiwan)
DS Audio’s most valuable optical analog cartridge

“The DS-E1 has an extremely clean music background, which can make the layering of music more open, medium and high The gorgeous colors and the wide sound field are all DS-E1 charms. Moreover, this price is not just a phono, but even a dedicated amp.”
“We buy it without thinking over because the sound is so brilliant and the price is so kindly !”

2020/4/22 New DS-E1 reviews are released
“Never – except maybe with the DS-W1 – have I heard such a three-dimensional sound image when listening to two-channel systems”

“He is stunned that such an inexpensive system can play so well. It even overshadows its own, sometimes much more expensive, cartridge pickups”
“The DS Audio DS-E1 is so convincing in every respect that not only he but also another acquaintance bought this cartridge through their respective dealers”

“Here’s where this cartridge system beats the competition I’ve heard:

None of the competition has that “open reel” quality of sound
None have a dead quiet background
None have the absence of haze you have grown accustomed to
None disassociate surface noise from the music better

I have not had a better listening experience with any other cartridge. It does everything you need a cartridge to do to get you closer to the music. When the “film” you have been listening through for all of these years is removed, you get the closest thing I have heard to an open reel.
At $2,750.00 for the cartridge AND the DS Audio Phono Stage/Equalizer, I simply cannot think of anything that is close. It is my new Audio Waypoint and a game-changer for me personally.”

ION-001 review in Taiwan(Chhinese)

One also notices better flow and a greater sense of ease in the overall presentation, an expanded sound stage in all dimensions, and richer harmonics of each musical entity as well as its ambient details.”

2020/1/16 New DS Master1 review

Positive feedback Brutus Award2019
“I can say that the results from the beginning and over time with the DS Master 1 have been nothing less than absolutely breathtaking”
“Many turntables, tonearms, and cartridges have come and gone over the past two decades. Frankly, I don’t think that I’ve ever heard better LP playback than the DS Audio DS Master 1 hosted by the NVS and the Durand Tosca. For transparency, clarity, detail, and purity of sound…for making grooves sound like master tape…the DS Audio DS Master 1 is top-o’-the-heap here in 2019”

2020/1/6 New DS-E1 review(Chinese language) is released
“DS Audio’s latest optical cartridge/phono-stage combo, the DS-E1, while priced at the low end in the lineup, achieves a performance level well beyond expectation. It retains most of the key sonic signatures of the top-end model with just slightly lower resolution and dynamic punch. In terms of background noise level, transient speed, and tonal accuracy, the DS-E1 is obviously ahead of conventional transducers at the similar or much higher price bracket. The clean, accurate and harmonic-rich reproduction of well-recorded piano music will quickly dispel any doubt the DS-E1 being one of the best buys in the analog-gear market today. Strongly recommended.”

2019/12/18 New DS-W2 review is released

“I have never reviewed a product that has invoked as dramatic an experience as the DS Audio DS-W2.”
“its strong and easily identifiable sonic traits which are unlike anything I have ever owned before. It fills void in my analog arsenal and nothing else sounds similar to it. It’s smooth and non-grainy character allows me to listen to music for hours without fatigue. It’s upfrontness and immediacy allows me to enjoy my small but growing collection of Jazz music with a realism which my system didn’t have before. It is an innovative and unique product that deserves my recommendation. Highly recommended!”

↑Cartridge evaluation list page of AUDIO magazine. DS-W2 scored 125 points and updated the cartridge category world’s highest score.
This is the highest ever score since the launch of the AUDIO magazine.

”It does not happen often that it makes me speechless.  But what the DS Audio DS-W2 gets out of a record really mocks any description.  
In terms of dynamics and transparency, I have never heard a better pickup in my life. ”

2019/6/10 DS-W2 review is released from Poland magazine

Poland magazine review

“The sound it offers is extremely comfortable. It is rich from the top the the very bottom, it beautifully shows the foreground, which is large, rich and strong. There is high dynamics here and great resolution.”

“It would be easy to call the DS Audio E1 optical cartridge and equalizer a benchmark at the $3k price point. I think that it’s easily a benchmark at twice, maybe even three times that price.”

“The game changer”

I think it could be the sixth biggest game-changer in cartridges in three decades. The other five? its older siblings.

40 years of Dream, True creation of Optical cartridge

It has been over 40 years since the first optical cartridge was introduced by Toshiba.
Number of companies followed this master minded concept in Analogue technology.

As a shooting star, it brightly appeared, and passed through Audio lovers’ minds with passionate sounds.
They showed us a simple fact that “Free from Magnet” and “Simplest electronics” could bring us overwhelming advantages in Record play back.

DS Audio succeeded this Master mind technology, inheriting their passion and love of music.
We are proudly announcing our DS Audio Optical Cartridge, DS Master1, to you.

This is our answer to those master minded pioneers in optical cartridge technology.
Without them, we never reached here. And most of all, this is our answer to those who love analog music worldwide.

We believe that DS Master1 brings you the ultimate capability of optical cartridge technology and the sound quality far reaching in different dimensions.
It would be our highest honor when this optical cartridge makes your audio life enriched and fulfilled.
