Preface
A little about me, I am not a professional reviewer, as I do this for the ‘fun’ of audio. I have been interested in audio for as long as I can remember, originally my interest started in home theater /surround audio. In time that interest grew into 2-channel audio and now personal audio/headphones. On a different note, unfortunately I have a debilitating autoimmune disease, that prevents me from working(or doing pretty much anything else) So audio for me is an important diversion/escape from my conditions. I can definitely ‘feel’ for any other members here who suffer from a debilitating condition. As they are life altering.
I have a wonderful loving wife, who ‘tolerates’ my audio passion, she doesn’t ‘get it’ but is supportive of it. I have tried ‘in vein’ numerous times to help her understand it and the ‘fun’ of audio, though it is not her forte.
Introduction

“Developed from the multi-award-winning transportable Hugo 2, the Hugo TT 2 is bigger, better and more advanced in every way. TT 2 sets a new benchmark for table top DACs, eclipsed only by our flagship DAVE.”
“Hugo TT 2 has been radically redesigned from the ground up, not only with beautiful new casework by Chief Designer, John Franks, but with 5x the processing power of the original Hugo TT and double that of the multi-award-winning Hugo 2. Hugo TT 2 distils over 20 years of digital development by Rob Watts and takes advantage of the very latest technology.
As expected, it delivers radically improved technical specifications and measurements across the board and exhibits drastic sonic benefits over its predecessor with 768kHz PCM and DSD 512 playback. Hugo TT 2 sets a new benchmark in table top audio, only being eclipsed by DAVE.
Delving deeper, in comparison to the 256-tap filters that traditional chip DACs may run at, Hugo TT 2’s beating heart is a powerful Xilinx Artix 7 FPGA, custom-coded by Chord Electronics’ Rob Watts, with 86x 208MHz cores running in parallel to create an advanced 16FS WTA 1 filter with 98,304-taps. Double that of its multi-award winning transportable brother, Hugo 2 (49,152). Hugo TT 2 also benefits from an upgrade from a 4-element design to a 10-element design, which works in harmony with the radically upgraded FPGA and code to deliver unrivalled audio.
A brand new high-power discreet output stage coupled with second-order noise-shaping integrated between the DAC output and filter is also employed to massively reduce distortion. Further improvements have also been made to the power delivery. Hugo TT 2 eschews the Li-Po battery power supply of the original and ushers in six super capacitors capable of delivering huge, linear dynamic currents when the music demands it with peak output of 5A, 9.3V RMS.
Hugo TT 2 also brings home the much loved four-stage user-selectable filter controls introduced with Hugo 2 and retains the three-stage user-selectable digital crossfeed function for headphone users who want to improve the perception of depth, similar to that of speaker
Hugo TT 2 can be upgraded at any time with the addition of M Scaler, our 1M-tap digital upscaling device.”
As I start this review off, I wanted to give A special Thank You to Todd Green, The Hugo TT 2 is on a kind loan from Todd As part of his loaner review program.
This introduction is based on my initial exposure and time I had with the Chord Hugo TT 2. So let’s begin the review.
As with all audio gear this is my personal subjective opinion. Everyone has their own preferences, which in turn makes everyone’s review subjective to their tastes and opinions.
In addition to the obvious volume marble and porthole window, the Hugo TT 2 comes in your choice of all black or silver and black. Unlike most other cord products the Hugo TT 2 has an LCD read out, located on the left-hand side. This LCD window is visible not only from straight on, but also from above. On the front panel, the unit has three buttons labeled menu, set, and power. The front panel also includes three headphone outputs, two of which are the standard 6.5mm (¼”) and the other is 3.5mm (1/8”).
The back panel of the Hugo TT 2 digital inputs include the standard USB input, two optical inputs and two BNC digital inputs. The dual BNC inputs are meant for adding Chord’s M Scaler. The outputs of the TT 2 contain the standard single ended outputs, three pin balance outputs and DX BNC outputs.
The Hugo TT 2 is noticeably absent of analog inputs, this unit is meant to be operated as an all in one Dac Amp combo a Dac only, outputting to a separate amp and preamp out to speakers. However with the lack of analog inputs you cannot connect your own Dac and use the internal Amp.
During the power on process of the Hugo TT 2, you will notice a few different things. First off it takes about 15 seconds or so to full power on and be in a ready to use state. Second you will notice on the LCD display it shows charge, this is for the process of charging the six super capacitors the TT 2 has, also the porthole window will start to show a multitude of different colors, This is part of the lighting effects the Chord Hugo TT 2 has.
Also of note, another interesting feature is the volume marble will change colors, depending on the volume setting.

First Impressions
I was able to spend a little time with the Hugo TT 2 and well I explain it like this:
Normally differences between Dacs are small, though those small amounts compared to my D90 and Bifrost 2, made all the difference for me. So (as an example) a 10% difference between the TT 2 and my D90/Bifrost 2, though that 10% equals quite a bit of an Improvement for me.
Regarding the unit as a whole, the amp section of the TT 2 in combination with the Dac, really is amazing. It’s more on the ‘neutral’ side, though for me specifically it adds a certain amount of ‘life’ or ‘reality’ to the music, plus the absolutely insane amount of detail. The great sense of space, air, positioning of instruments/imaging, separation, stage, dynamics, and on some tracks (especially live recordings) the ability to hear the room or space the music was being played in(as it transports you ‘there’).
This is what I took away from The TT 2 and why it has impressed me so much. The TT 2 was ‘game changing’ for me. As I never thought that small little percentage of difference, would equate to such a ‘significant’ improvement for myself. Plus I have found that I ‘Really’ like the ‘house sound’ of Chord products! I thought I had my endgame amps and dacs, I was wrong, the TT 2 takes it to the next level and for myself it is ‘exactly’ what I have been ‘looking’ for. I have no idea how, but eventually I really want the Hugo TT 2 in my system. For me it truly is THAT Good!
Sound
Smooth and detailed are the words that come to mind when describing the sound of the Hugo TT 2. Amazing detail yet it is smooth in it’s presentation, without adding any harshness or sibilance to the music. The custom FPGA chip designed by
@Rob Watts in the Hugo TT 2, is more resolving and smooth. In comparison to the AKM 4499 chip in my Topping D 90. This amongst itself is impressive as AKM chips in general, have a wonderful “velvety” sound signature to them. In my opinion this is bested by the custom FPGA chip in the Hugo TT 2.
When using the Hugo TT 2 in it’s intended all in one form. It offers a very engaging yet pleasant sound. This did not change with all of the headphones I tried, including the Focal Elex, and Elegia. The HifiMan Ananda’s all the way to my Sennheiser HD600’s. The presentation the TT2 offers remains engaging and pleasant throughout. As I mentioned in my ‘first impressions’ the Chord Hugo TT 2 has a great sense of space, air, positioning of instruments/imaging, separation, stage, dynamics, and on some tracks (especially live recordings) the ability to hear the room or space the music was being played in(as it transports you ‘there’). This ability of the TT 2 to convey the sense of space, along with the imaging capabilities, is unlike any other I have currently heard! It’s almost as if I am able to hear around the notes, as it gives you a 3D(being there) presentation.
The Dac portion of the Hugo TT 2 paired extremely well with my SPL Phonitor XE amp. Also paired very well with my Hagerman Audio Labs “Tuba” tube amplifier. Though the Dac portion of the Hugo TT 2 pairs very well with many of my amps. I still prefer to use the Hugo TT 2 in its intended, all in one form factor. Which in my opinion yields the best possible sound. As another forum regular mentions, adding an external amplifier to the chain will only increase noise, however this was not ‘audible’ with the SPL Phonitor XE amplifier.
The Dac portion alone does a phenomenal job of extracting and relaying incredible amounts of detail. Timbre is not quite as natural as other Dacs, As the smoothness of the FPGA chip, slightly takes away from a completely natural sound. Though this does not take away from the pure engagement and enjoyment of this particular Dac.
The amp portion is very competent in its performance, It is highly resolving, excels in terms of its raw detail and micro-dynamic resolution. I felt nothing was gained in pairing the TT 2 with my Phonitor XE amp. Using the Hugo TT 2 in it’s intended all in one form, will yield amazing performance for all headphones with the possible exception of all but the most demanding headphones such as the notoriously hard to drive HifiMan Susvara’s.
Though the Hugo TT 2 does offer numerous filter and crossfeed settings. I kept both of these in their default settings, incisive neutral for the filter and crossfeed set to off for the purposes of this review. I have not tried any other filter settings nor any of the cross feed on settings. Due to this I cannot speak to how the use of the different filters or crossfeed settings affect the sound.
Summary
I wasn’t sure if I was going to like the Hugo TT 2, as I thought to myself how much better could a $5500+ Dac actually be? As I mentioned in my initial impressions, when you reach a certain level, the differences in Dacs is not huge, you are talking about small percentages and signatures. However the Chord Hugo TT 2 has given me the best listening experience I have ever had and I do mean experience, as this is more than just listening to the music. Chord Electronics makes some absolutely phenomenal equipment. I highly recommend you check them out, especially if given the opportunity to audition some of the products in your own system.
