Jacob Heilbrunn previewed this “phono preamp” at the Capital Audio Fest and rated it the “Most Significant New Product”. It provides equalization solely for DS Audio optical cartridges. Jon Valin is fond of several DS cartridges as he has explained in the pages of TAS. Ed Meitner discovered a similar fascination: “Initiating a collaboration with Tetsuaki Aoyagi, head of DS Audio, Ed purchased the W2 optical cartridge for development and was impressed during his preliminary listening experiences. Compared to his reference MC cartridge, the W2 exhibited improved resolution, clarity and low frequency response. This motivated Ed to dive back into the world of vinyl playback, resulting in the first EMM Labs optical equalizer, the DS-EQ1, designed exclusively for interfacing with DS Audio optical cartridges.”

"Two years ago I reviewed the first iteration of a DS Audio cartridge, the DS-W1 “Night Rider,” and though, as you will soon see, several things have changed for the better in the DS 002, the basic operating system remains the same. If I may quote from that review without again being accused of going soft in the head, here is how it works: “The cartridge uses a light source (a miniature LED) that is powered via tonearm cables and internal tonearm wiring by an outboard equalizer/power supply (which you must purchase along with the cartridge and which replaces your phonostage). The record-groove vibrations transmitted by the stylus/cantilever modulates this LED light by means of an ultra-low-mass screen or shutter attached to the cantilever. This modulated light is picked up by the photodiode, which converts the light into an electrical signal, sending it back through the tonearm wires and interconnects to the equalizer/power supply unit where it is RIAA-equalized and amplified into a line-level output"

Mine is scheduled to arrive tomorrow. Moving up from the DS-EQ2. I think the EQ2 is fantastic, so I can't wait to hear the EQ1. I am running the Grandmaster cartridge.

It was worth the wait. I think the EQ2 is likely the price/performance sweet spot, but the EQ1 adds so much more presence and depth to the presentation if your system supports it. I am over the moon with the DSAudio Optical Cartridge system.

I have heard that the EQ-1 takes a long time to warm up (24 hours or so). Do folks leave it on, and if you do, do you turn off the power to the tonearm? Appreciate your input.

In the literature on the DS Audio 003 EQ, they recommend leaving the power on for a minimum of a month, as the substantial Electrolytic “Filter Bank” (330,000 uf), needs a long time time to “break in”.
Not sure if the Meitner is any different, but I suspect it also requires a long time to settle in.
Cheers....
