Class B rated in Stereophile
Now shipping in black and silver
In the latest review from Stereo Magazine they sum with:
"the DSPeaker Anti-Mode X4 is much more than "just" a high-end room processor. It handles all tasks from conversion to operation to pre-amplification on the highest level. It also offers the extremely useful extra of very simple Plug 'n' Play room correction as well as many possibilities for individual adjustment."
"If you want to give the subject of room calibration a chance or are on the hunt for a good digital preamplifier,the DSPeaker X4 is definitely the ideal partner. That’s how fun "multiple choice" can be!"

The DSPeaker X4 is a 4-channel Audiophile Preamp/DAC with room correction, electronic crossover and excellent headphone amp. It can be used to biamp the Emerald speakers or any other speaker or add subwoofers.
Speaker-room interaction is typically the most important performance-limiting factor of any high-end audio system. Every listening space introduces errors that can be in the magnitude of dozen decibels or even more. These errors are most pronounced at the bass and lower midrange regions, where the classic acoustic treatment loses its effectiveness.
The DSPeaker Anti-Mode X4TM preamplifier/DAC combines an uncompromising selection of audio electronics. It was designed with one purpose in mind: to elevate to a new high what is possible in stereo sound reproduction in the domestic environment.
The installation procedure is automated. Anyone can achieve superb results without any prior expertise or knowledge. After a brief calibration process Anti-Mode knows your listening space in great detail and designs custom filters required for your unique space. You may be very surprised to hear what your loudspeakers can do!
The Anti-Mode X4 covers a wide variety of use scenarios, ranging from the traditional "2.0" two-speaker configuration to more exotic installations featuring a number of subwoofers with multiple listening seat optimizations. The best cross-over frequency is automatically determined for speakers and subs.
In addition to the automatic correction, the user has full reign over extensive tone controls and custom filters. The preferred sound signature can be altered even in real-time, from the convenience of your listening seat. Different settings can be stored in memory for a quick recall at any time. Most functions can be accessed with the supplied full-aluminum remote or using the control wheel located at the front panel.
A modern, easy-to-use graphical user interface is provided. Room response graphs can be inspected in full detail without the need to resort to personal computers or other additional equipment. A built-in graphic design tool is included for all types of sound enhancements.
Kalman Rubinson in Stereophile reviewed the Anti-Mode X4 in Music in the Round #97. He said:
"I'm happy to tell you that DSPeaker's Anti-Mode X4 is great just as it is, and will appeal to user needs that until now have not been addressed. This is a first-rate two-channel preamplifier with flexible bass management and potent DSP for setup and room EQ. It requires no additional parts or a computer— everything is already built-in or is supplied by DSPeaker. Even better, it requires no additional technical background"

"...offers the wonders of DSP correction with ultra-high sonic quality"
"it is Alladin's genie except you get a lot more than three wishes!"
- Dr. Robert E. Greene / TAS September 2012
See the superb review in the February 2013 Absolute Sound where Robert summed up with:
"In the end you can get truly remarkable sound out of a system corrected and adjusted with a DualCore. One thinks of the introduction to The Three-Penny Opera: “Conceived with a splendor that only a beggar could imagine and ….so cheap that even a beggar could afford it.” Well, not quite that cheap. But still a wild bargain, and a sonic wonder.”

In Paul Seydor's Newport Show report from the 2014 show he says:
Most Significant Product:
I can’t think of another investment that will bring more improvement in sound for the dollar than SimpliFi’s Dual Core Antimode DSP with or without the ULN-3 PSU optional power supply
Part Time Audiophile said:
And that’s when Walter showed the Ace he’d tucked up his sleeve: the DSpeaker Anti-Mode Dual Core 2.0 he was using as a preamp. Walter A/B tested this device for me, cutting the room correction in and out of the chain; the DSpeaker greatly cleared up the midrange and upper bass regions to an extent that I would have thought improbable. All I can say is: “more demo rooms at audio shows need this”. Assuming you don’t want to schlepp a couple hundred pounds of room treatments across the country, it really can nail down an unfriendly room, and do so with some shockingly great results.Wickedly cool.

NOTE TO OWNERS OF THE ORIGINAL 2012 DUAL CORE
The original Dual Core had the standard / typical RCA and XLR input / output sensitivities which worked fine with sources and downstream devices which adhered to these standards.
Based on customer feedback and to cater for a wider range of sources and down stream devices DSPeaker have now increased both the input and output sensitivities....
If you are an existing Dual Core user and did not encounter ' input clipping messages ' this upgrade is likely of NO BENEFIT to you. We do take older 2012 models in trade for the new 2013 version if you have clipping issues.
