DSPeaker Anti-Mode X4

MAKE AN OFFER!!!

For sale is the DSPeaker Anti-Mode X4 preamplifier/DAC with DSP room correction, DSP crossover, digital and analog inputs and outputs, and sophisticated headphone amplifier with HRTF DSP correction. It is a unique "Swiss Army Knife" of a component combining as it does, so many functions in one very easy to adjust and use unit. No computer is necessary to set up any of the functions; the unit itself, combined with the included measuring microphone, boom stand, cabling and built-in test tones does it all, quickly and easily. It is by far the best-sounding and easiest to use equalizer ever.

The X4 is a full featured 4 channel remote controlled balanced preamp with exceptional DSD DAC and very high quality headphone amp. It will outperform most high end preamps as room correction is amazing, and makes a far greater sonic upgrade than minor preamp differences. It features a large internal power supply. It can be used as hi-end room correction only, a preamp with room correction or a preamp with DAC and room correction.
The 4 channel X4 can run subs and mains, or be used to actively bi-amp your speakers. It has an internal parametric EQ and 6 presets for different tonal balances or for correction at different seating positions in the room.

Anti-Mode X4 is DSPeaker's newest loudspeaker and subwoofer optimization system and is capable of perfecting the acoustic performance of any full-range stereo audio system.
It is based on the new Anti-Mode 3 algorithm which refines the popular Anti-Mode algorithm even further.
Anti-Mode X4 can be connected to almost every audio system.

This unit was purchased new by me in April of 2018 while attending AXPONA, immediately after it's release. I received it in June of 2018. It is in excellent cosmetic condition and functions as new except that the firmware has been upgraded as new firmware was released by the manufacturer so that it now performs even better than when it was new. The unit has never needed repair of any kind and has not been modified in any way. This unit should be rated at a 10 because it sat in it's packaging for a while before it was put into service because I moved and had other priorities. It was over a year old at the time of listing, so I rated it a 9.

I am selling this unit because I have purchased a pair of Sanders Sound System speakers. These come with a pre-programmed EQ/Crossover, that Roger Sanders approves for use with his speakers. This DSpeaker X4 is therefore redundant, My loss, your gain.
