The DAC that is taking the world by storm. This top of the range May range is a full discrete R2R type audio decoder and does not have off the shelf-DAC chip. This is a bespoke custom-designed core DAC module and truly a breakthrough with technology for any DAC chip today. 

The May here to achieve new heights, new dynamics and simply a full spectrum of audio to please the aural senses.

The Holo May is known for its natural Analog sound with no compromise and having the best measurements of NOS R2R DACs. It delivers an intoxicating sound signature that Holo Audio is known for.

We offer 3 versions of this fantastic DAC:

  • Level 1 Standard USB Module, Copper Roundwire Otype transformer, Shurter fuse, no Remote Control, USB Cable
  • Level 2 Standard USB Module, Standard Copper Roundwire Otype transformer, HoloAudio Caps, Schurter Gold Fuse, CNC Remote Control. USB Cable
  • KTE Version - Enhanced USB Module w/ Titanis 2.0 circuit, Flatwire Otype transformer, Handselected dac module, HoloAudio Caps, 4N Silver 1.5mm wire at IEC inlet, HoloAudio Red Nano Fuse, CNC Remote Control, Copper KTE "fox" logo emblem. USB Cable 

The DAC can be supplied with an optional analogue Preamplifier. Please contact us about this option. 

The current manufacturing lead-time is approximately 6 weeks. 

Please contact us if you are interest in this DAC, we are happy to provide answers to all your questions. 

Twittering Machines Review:

"With the Holo Audio KTE May DAC we have a digital to analog converter that pulls off that rare feat of turning data into music without imposing the fingerprints of the process, which is all too commonly found with most DACs. That it does so at this level of sophistication at its price is remarkable." 

Part-time Audiophile Review:

"The sound of the Holo May DAC is a bit of an elusive thing to describe. For the R2R enthusiast the May does not trade in the fanciful frequency colorations, college-party dynamics and slam or other antics that some have come to expect. Instead it resides in the company of those rare DACs, most of them at least twice the price of the May, that present auditory honesty in such a refined way that you can’t help but want to listen to music. I listened to my stereo far more frequently than usual when the May passed through my system, and were I buying a standalone DAC in the cost no object category, the May DAC would be on a very short list of extremely serious candidates. For the true digital enthusiast this is a must hear."

The new generation of linear compensation technology solves the accuracy errors caused by resistor tolerance, after compensation, reaching a variance of 005% tolerance accuracy. Proprietary anti-jitter technology that provides a full amplitude of anti-jitter without increasing noise floor and other undesirable effects. Based on this new generation of technology May “can provide a SINAD of >115dB and a dynamic range of >130dB, which represents the performance limit reached by today’s most advanced R2R architecture DAC.
Using the ultimate performance of PLL+FIFO technology, provides 0.1Hz Third-Order low-pass ability to inhibit jitter. It also uses a high-performance femtosecond VCXO as the PLL clock source. Under the premise of being almost immune to the front-end jitter, it can also lock up to 1.5us-2us @ 1KHz signal with high jitter. (It can lock up to 1.5us-2us @ 1kHz signal with high jitter on the premise of almost being immune front-end jitter).
Dual Mono DAC L/R channels are independently powered by their own dedicated transformer in the PSU chassis. This provides better channel separation and more accurate sound stage.
Official Support USB and I2S up to DSD1024 and PCM1.536MHz sample rate. The USB interface uses proprietary firmware with ultra-low latency, a highly reliable data transmission, ideal USB eye pattern measurements that contributes to 2-4 times higher performance than official firmware. Two sets of independent HDMI-I2S input interfaces are provided, and each set of I2S has a four-way independent circuit, as opposed to standard LVDS chip, making I2S clock signals subject to lower interference and lower jitter. In addition, each group of I2S inputs can be configured with specific pinout configuration, making it compatible with most of the HDMI-I2S digital devices on the market.
