    Received the essence hdacc today. Got it hooked and setup. It does exactly what I was needing. Works great and easy to use! Sounds great too, though I have about two minutes so far listening.

    Thanks, and I also appreciate the informative discussion we had.

    Hey Bob
    Yes sir, you can quote me. I am very impressed with both the Mitchell & Johnson GL2 electrostatic headphone and the HDACC’s performance. I store my digital files on a NAS that I stream through my OPPO BDP 103 to the HDACC. Being able to monitor my audio files with the OLED display is a bonus. Passing 2 channel audio using the HDMI out on my OPPO through the HDACC to my 2 channel setup sounds outstanding! This alone was worth the purchase price. The upscaling is also wonderful it gives my low-res files and LPs a welcome punch that they were lacking. Steve Fast, Audiophile Consumer, Feb 2017

    Hi, Bob.

    I’ve been playing with the HDACC for a few days and I absolutely love it. My music collection have never sounded as crisp.
    I connect a blu-ray player with hdmi to it and send the audio with rca cables to a tube amp and picture to a tv via hdmi out. This way it works perfectly. Espen Christensen, Audiophile Consumer, Norway Feb 2017

    Hi Bob,

    Got the HDACC a week or more ago but haven’t had time to hook it up until now. So far I’ve hooked it up to the coax dig out of my old Micromega CD player (with modified transport) and am using it as a DAC to feed to my own design/built 2A3 single ended triode amplifier into Audionote J loudspeakers. It sounds absolutely fantastic! I got it to extract the HD audio from HDMI which i’ll get to but i’m loving listening to it as a super quality DAC for now. Awesome job!

    I simply love the HDACC so much. This is the first time I feel the power of my ProAc D18 speaker since I brought it back in 2012. The HDACC gives the CD music so much clarity and power. I enjoy so much the very details of different sounds in the song. I must say that the HDACC is a “must have” device for all audiophile beginners. That would save us a lot of money from buying various audio components in order to experiment the right choice of equipment and the mix of them. Eddy Lam, Hong Kong July 2016

    This site already has plenty of reviews and recommendations on the HDACC so I won’t go into any detail on that other than to say it really is as good as people say. I was particularly impressed with the sound quality of the Blu Ray soundtracks. The main point I wanted to make was about the after sales service and how helpful Bob is. My system quite old but still works and sounds great but being old it has its limitations, the old amp only having 3 inputs for example. As my knowledge of these things is also a bit “old school” I needed quite a lot of help in setting up and configuring the HDACC. Bob was extremely helpful, patient, clear and concise with the assistance he gave and I cannot thank him enough. If anyone is considering buying an Essence product but has concerns over their own ability to get the best out of their purchase, I would urge to go ahead as help will always be at hand.

    HDACC = Great! The HDACC arrived yesterday and and the setup was easy for my minimal setup. Two inputs: Cambridge Azur 840C passing through 44.1/16 over coax and Sonos player delivering 44.1/16 over Toslink. It sounds better to me than the upsampling Cambridge DAC section I had been using. The headphone amp is also noticeably better than that in my old Sonic Frontiers pre-amp. Very Happy! Anonymous Audiophile Consumer, March 2016

    Hey Bob,
    Came home today with a new set of HDMI cables. Put them in. Kept thinking of “pilot error” Hmmm. Went over set up options on my Oppo player, once again and again. Finally found setting for “dynamic range control” Set it to “off” . It was set to “auto”
    Popped in a redbook cd. Magical! Then did some Pandora radio. OMG! Then, finally popped in Yes, Live in Montreaux Blu-ray, chose DTS-HD in audio options. Voila!! The HDACC reads 48k- on the left side. In Heaven. I cant thank you enough for your expertise and patience. I am sooooo happy with this product!!!

    WOW! Well Bob, I’m pretty much all hooked up! I received the Essence unit last Friday, a week ago, and have been putting it through its’ paces— let me tell you, my friend: you have a g-r-e-a-t product!! It’s enhanced my sound and I can use it a variety of ways , plugged in as it is. I’ve connected XLR’s to my STAX 4370 unit and what a difference this makes. I have my iBASSO DX-90 connected to the coax input – holy caramba!! – and my Hifiman Hm-901 to the analogs. THANKS FOR REKINDLING MY PASSION FOR AUDIO – YOUR HDACC IS JUST WHAT THE DOCTOR ORDERED!

    Several weeks in and I’m re-discovering lots of my existing collection of music, and looking forward to even more by adding some blu-ray audio discs played back via HDMI. The Essence HDACC has been a swiss army knife of digital audio goodness for sure. I’m looking forward to getting to use it with a pair of slightly older Acoustic Energy AE1 MKII speakers . I suspect that 2 great things that sound great alone will be exponentially better together. 2 thumbs, arms and hands UP, Way way up! Jamal Kirk, Boston, Winner of HDACC Summer Sweeps 2015

    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

    Gerald Pratt, noted audiophile and HDACC owner, 2014 – February 13, 2015

    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.

    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
