A Boxful of Digital Audio Ingenuity

The Essence HDACC is an amazing digital-to-analog converter, but it’s much more than that. It’s also a versatile digital preamp with remote control and enough inputs to handle your analog and digital music sources: LP’s, tapes, disc players, network music players, smartphones, tablets, and PCs.  

What puts this DAC in a class by itself is it’s HDMI input, with analog output, so legacy analog audio systems can now play uncompressed Blu-ray Concerts, SACD, and Hi Res Downloads with all the dynamic range of the live performance, bit-for-bit identical to the original master recording.

    I am very satisfied with HDACC and it’s still connected to my Yamaha CX-A5000 and my hi-end computer with 5.1 system :) Salute for you…Hendra Wijaya, inboxgue@gmail.com

    As I write, I am playing an AIX recording “The Latin Jazz Trio” I picked up about a year ago. I wanted to hear what the Bluray audio high resolution sound was all about. I am really impressed as in wow I almost can’t believe the dynamics and tone I’m getting right now….I did not hear anything as good at the AXPONA show at any price point…You’ve got a winner. Congratulations on choosing to license the Bluray protocol. If I wasn’t hearing it myself, I wouldn’t believe what I’m hearing….I hooked up a turntable and phono preamp to the line input. If there was going to be any loss of detail, here is where I expected to find it. I put on a record and cued it up. I couldn’t tell the difference between an excellent solid state preamp and the digitized version out of the HDACC. Truly a versatile product. Steve & Julie

    I come from the old-school of audio and have spent years configuring the best high-end audio system I could come up with. The speakers are Apogee Divas, the Amp is a Mark Levinson and the Pre-amp is a vacuum tube device of my own design. I had no interest of changing to a AV system with all of the AV formats that evolved as the technology was advancing.

    When I learned from Bob on a LinkedIn site about Blu-ray’s ability to play not only high-end video, but high-end uncompressed audio, I wanted to jump on the bandwagon. This would be as good, or better than the best analog open-reel tape recorder playing a master tape. Turns out it is the best audio source available to audiophiles.

    The first Blu-ray player I acquired has audio output connectors that provided a great audio 24/96 signal from its internal DAC. But I liked the idea of deriving the highest quality signal from a dedicated high-end DAC and the HD audio center seemed to have it all including a remote control with volume control capability which I did not have with my analog electronics. It turned better than my expectations and I have been playing Blu-ray music ever since.

    I recommend you read Bob’s articles which describes how this all works and how most audiophiles are not aware of the audio quality as most thing Blu-ray is for Video performance only. The HD Audio Center can provide a single-ended output or Balanced XLR outputs as well and requires no other Pre-amp to work into a high-end power amplifier. However, it can also be connected to an analog pre-amp as well. I tried both ways and preferred using my tube Pre-amp for two reasons. First the sound seemed a little warmer and musical to me thru my Pre-amp and I liked the idea of using the volume control on the analog Pre-amp as a limiter for the extreme dynamic range of the Blu-ray format.

    You need to be a little careful when you have the full dynamic range of a 24/96, uncompressed recording. But when played back at normal listening levels, say around 80 dB, the dynamic range will blow you away. This is a great product and I recommend it highly.

    Hi Bob,
    just a note to thank you for the info regarding the use of an HDMI de-embedder, I have now connected my Oppo 93 this way and, as you suggested, the overall sound quality and dynamic range is the best I have ever heard on my system. Chris Botti, for example, is really outstanding. I use a Bryston DAC, Audio Research LS27 pre, 4 Bel Canto 1000 mono-blocks and Dali Megalines with JL Audio subs so the differences are really felt and heard. Thanks again, Robin McConnell, So.

    “After a lot of extensive listening yesterday with high quality lossless CD rips, I feel that the HDACC is a step up in terms of audio quality over the Matrix DAC….the Essence has wider imaging and overall a smoother sound. Having an HDMI input is a total win for me. I think you’ve definitely hit the nail on the head with this product. The headphone amplifier is superb.That particular OpAmp is designed for high impedance headphones like the ones I use and I was astonished to discover the new life the headphone amp in the HDDAC put into them. Thank you for making this wonderful product” Amol Akalkotka, HDACC owner, June 2014

    Are you considering buying a dac this year with usb 2, a headphone output, and preamp features? Before you buy think about this- are you going to watch movies on the system at least half the time? If you have a blu-ray player and you answered ‘yes’ there is only one choice: the Essence HDACC. On a budget? Do a search on netflix, or even better your local library, and see how much blu-ray content, both music and film is out there- it will surprise you.

    Success!! Received the HDACC last night, and got it set up and sorted….. and WHOA….. like a brand new …everything!
    Pretty amazing to hear the difference… a movie on the cable box let me hear the gravel being picked up by the tires on the screen… CD’s at 44.1 or WAV files at 48 were entirely new experiences… ripped movies, regular DVD’s…. And then to top it off, the sample CD you were kind enough to include. That first track put shivers up my spine. Bob, thank you so much this thing is unbelievable. I can’t wait to keep trying new content, and to find a few blue ray audio discs (which are hard to find so far, but I’m on it) and put those through the paces. J. Kelly Moran, audiophile consumer, Vancouver, Canada

    Hey Bob, how have you been? My audio journey has slowed down tremendously as my rig is at a place I truly enjoy, and a big part of that is your HDACC. I’ve now compared it to the wyred 4 sound dac2, the oppo 105, and the chord Hugo Dac. Yours still comes out on top for me. Derek S. 10/15/14

    I’m wanting to move from an vintage analog preamp to a DAC pre. The HDMI option not to mention analog input makes this super flexible. The Blu-Ray aspect is unique and something I know I’m going to love. Nice design! Bill McCormick, Audiophile consumer, SC

    Hi Bob,

    I am very happy to see that someone is finally making affordable audiophile- quality equipment with HDMI input – Bravo!. Up until now, no one has taken this ubiquitous interface seriously other than for the transmission of i2S signals for whatever reason. I have been using an HDMI de-embedder to send BR quality music to my NAD M2 for some time now, but before that was sending those sigmas to my DAC.

    Meridian has been making a very expensive HDMI input unit for some time now, but the output is proprietary and therefore will not work with non-Meridian equipment. I commend your vision for recognizing the need for this product in the marketplace Jack Neber, NY Audiophile, Jan 31, 2014
