This isn't anywhere near the first review of the Chord Electronics' Hugo. I'm very happy that I'm finally getting to hear it, though, because from what I've read I feel as if I've been missing out on not only a very unique component, but an excellent one. Since it is a portable DAC/headphone amplifier the guys and gals at Chord Electronics named this rather small palm-sized player Hugo -- because you can take Hugo wherever "you-go". Get it? To make it go wherever you go, it includes an internal battery-charging circuit that enables one to play music for up to 10 hours without re-charging. Once you arrive at a wall outlet it takes it about five hours to reached a full charge, but can be used again long before it reaches that full charge. My guess is you will be listening to it while it's charging.
The Hugo's DAC is based on the ofttimes used
Field Programmable Gate Array (FPGA) DAC technology that Chord has used in past
digital products. Field programmable indicates that it can be configured by the
user, in this case Chord Electronics. It is able to handle much larger and more
complex digital processing instructions, and is also very fast. The converted
music signal is the beneficiary, and as a consequence, the listener. Another
advantage of using FPGA technology is that the engineers at Chord were able to
customize it to alter its slew rate and drive strength on each output pin, which
decreases the amount of ring that might occur -- and there are other
improvements that affect the resulting signal that is delivered through its
analog outputs that are discussed in prodigious detail on the Chord Electronics
website. The Hugo is also a very flexible device, not only because it has so
many digital inputs, but because of the processing power of these inputs. Its
internal DAC can decode digital signals up to 384k with a word length up to 32
bits, and is also future proof in that it can decode DSD 128 data. It comes not
only with the now standard RCA coax and optical inputs, but two types of USB,
one for the ubiquitous flash-drive and other portable data carriers, and the
other for what is now standard in most modern listening rooms, USB 2.0. The Hugo
is also A2DP Bluetooth capable, and uses a custom-made module with the aptX
codec to feed its digital signal directly to the DAC. I will freely admit that
I'm not very familiar with or use Bluetooth very often, but my teenage daughter
certainly does, so I have no doubt that she not only appreciates this wireless
function, but expects it when listening to music coming from her iPhone. In
regards to more technical information regarding the Hugo, again, there is an
abundant amount of information on Chord's website. It's obvious that quite a bit
of research and development went into not only designing the Hugo, but
implementing its technology into a very user-friendly device.
As I started writing this review Chord announced that an optional leather case for the Hugo was being made available. Chord says that they spent quite a while discussing the details of this case with dealers, their distributors, and especially their customers. The "high-quality durable leather" case is available in black or tan, and uses a "quad system" of elastic webbing straps with Velcro ends to hold one's player, whether this be an iPhone or other mobile digital device, to the case. Of course it allows full access to all the Hugo's controls and indicators. They also posted on their website that the Hugo's silver hard-anodized casework is also available finished in black.
The headphones I used were more often than not the top-of-the-line Grado PS1000, but also the very good Oppo PM-1 planar magnetic models that come surprisingly close to the high standard set by the Grado, but present the music from a different perspective. From time to time I used my 15 year old Sennheiser HD-600 that was rebuilt by Sennheiser USA late last year. Of course I couldn't resist using the Hugo as a DAC in my main system, and I bet that most readers would be disappointed if I didn't. This system is not quite state-of-the-art, but I consider it a cut above most mid-level high-end systems. Its digital front-end is built around a Dell PC used as a music server that has been configured to handle high-resolution digital files using its USB outputs. The open-source Foobar 2000 reads files that are stored on a number of multi-terabyte hard-drives. A Furutech GT-2 USB cable connects the computer's USB output to the USB input of the DAC. The Hugo's analog outputs were connected to a Balanced Audio VK-33 preamplifier (see next month's issue of Enjoy the Music.com's Review Magazine for that). The power amps were either vacuum tube driven PrimaLuna DiaLogue Six monoblocks or a Pass Labs X350.5 solid-state, speakers were either the dynamic Venture Audio Encore speakers (see review in the May issue) or a pair of my resident Sound Lab DynaStat hybrid electrostatic speakers.
When I started writing this review bassist Jack Bruce died. Of course most remember him as the stunning bassist, vocalist, and song writer for the super-group Cream that was on the scene from 1966 to 1968. Although I was too young to be aware of their existence when they were together, apart from the hits they had on pop radio, this band and Jack Bruce's stellar bass playing made a huge impression on me as both a music lover and a budding musician -- and continues to this day. As a young man my friends and I used to call his position in Cream "lead bass". Each and every song on each and every one of Cream's albums are etched permanently on the hard-drive located in the medial pre-frontal cortex portion of my brain, and this data remains easily accessible. I was in my late teens when I discovered Jack Bruce's solo album Things We Like, released in the UK on Polydor in 1970 and in the US on Atco the following year. The CD was released in 1992 on Polydor Japan, and I ripped my copy onto my computer using Exact Audio Copy, which converts the files to FLAC as it saves it to hard-drive. I also made a 96kHz/24-bit version burned from the LP when I had a sample of Benchmark Media's ADC USB1 in my system. I play this excellent album rather regularly, and even though I don't need an excuse, it was Jack Bruce's death that compelled me to play it through the Hugo for some late-night headphone listening. This album features Jack not on his Gibson EB-3 electric bass through a stack of Marshall amps a la Cream at the Fillmore West, but on acoustic double bass. He is joined by none other than John McLaughlin on electric guitar, plus his old friends from his Graham Bond Organization days Dick Heckstall-Smith on soprano and tenor saxes, and John Hiseman on drums. I was blown away when I first heard this album, even though it had lots of straight ahead 1950s style bop, it was infused with even more 60's free jazz which I was really into during my formative years. Even more surprising is that the album was recorded in London in 1968, at the height of Cream's success. It seems I'm not the only one who thinks this is a great album because according to WhoSampled.com, samples from this album have been used by over 20 artists ranging from DJ Jazzy Jeff & The Fresh Prince to A Tribe Called Quest.
The sound quality on the album isn't the best
there ever was, but regardless of which version I listened to, the Hugo really
nailed the sound of Jack Bruce's bass. The low-end response of the Hugo is
excellent, with a warmth that I wouldn't expect from a solid-state unit. The
bass frequencies seemed to go as low as the recording captured it when it was
recorded live in the studio, and Jack's bass is mic'd close enough to hear the
buzz of the strings against the fingerboard. The Hugo was able to capture
details in the recording without ever sounding etched, and it was able to detect
the touch of studio reverb added to enliven the sound of his bass a bit without
it sounding out of place or drawing attention to itself. Even better was how I
was able to get lost in the band's playing, especially by the time I reached the
tunes that were originally on side two of my Atco LP pressing. The band's mood
gets more and more introspective during the second of these three songs, and by "Ballad
For Arthur" things take off with Jack Bruce playing repeated lines for the other
musicians to comp off of. The session becomes more animated when McLaughlin
begins to play in a style that many will recognize, because he joins Miles
Davis's band not long after these sessions were recorded. The Hugo's
microdynamic shading was also excellent. I was given the impression that I was
hearing a note start before they started playing it, and if you've ever heard
top-flight headphones through a top flight headphone amp you'd be able to
decipher this fairly obtuse description. When these traits are
combined with a more than occasional outside-the-headphone soundstage these
affects gets rather eerie. Suspension of disbelief is one thing, but to feel as
if you are one with the musicians on the recording is another thing entirely,
and the Hugo is able to pull this off. Yes, the Hugo resides with other
equipment in its price class where an audiophile would and should demand that it
should be endowed with properties such as extended frequency response, low
noise, zero distortion, etc. But when these are combined with attributes such as
when instruments and voices take on the semblance of the real thing, regardless
of the complexity of the material or genre of music, and
be transparent enough to be able to make itself disappear as a link in the audio
chain, combined with what could only described as rendering the gestalt of the
music which is a term sometimes used to describe when the sum of these
musical characteristics are greater than the whole is usually only found in
a handful of more expensive, expertly designed components. A "rightness" if you
will. This is what makes spending more for a component worth every penny.
Hi-Res Audio Files With The
Even though the soundstage that is produced when listening through headphones is very different from what emanates from a pair of speakers in a listening room, headphones are still able to separate the instruments and voices from one another and create, although quite artificially, a soundfield that somehow puts distance between the sounds that are generated. The Hugo possesses this quality in spades. When listening to the Electric Warrior album it is as if I'm surrounded by the band in the studio, and as a benefit these instruments and voices materialize not only around my ears and in front of my forehead, but break through to the boundary between my skull and the outside environs. Many have complained that they don't like the "inside the head" music produced by headphones, so there are some headphone amplifiers that have a cross-feed circuit that places some of the material from each channel into adjacent channel to eliminate some of this effect. The Chord Hugo has three levels of the amount of cross-feed, and it works as advertised. Personally, I've never liked using a cross-feed circuit. On some headphone amplifiers that use this circuit I hear a decrease in transparency when it is engaged. I don't hear any loss in transparency when using this circuit on the Hugo, but it doesn't improve the sound I'm hearing, it just changes it. Different doesn't always mean better. For those who use high-quality headphones, which produce less of this "inside the head" sound than less accomplished models, they most likely will not need to use this circuit anyway. For others, the Hugo is the only headphone amp I've ever used that has three increasing levels of cross-fade, and if they like the resulting sound, they will likely be able to discover the level of cross-feed that satisfies their needs.
I used the Chord Hugo as an outboard DAC in my large main system. It was able to easily bypass the Hugo's volume by pressing the cross-feed switch while powering the unit, as I described earlier. To connect the Hugo to my music server I had to use the USB cable that was provided with the unit that had a mini connector on its business end, but needed to acquire another slightly longer one for my needs. Neither had any audiophile credentials that I could discern, so I tried to keep this in mind when listening to the music that was produced by the Hugo. In the end the type of cable was hardly worth mentioning. Other than not being the most ergonomically convenient DAC when used this way (it's rather obvious that Chord focused their design for the Hugo to be used as a headphone amplifier, a portable headphone amplifier in fact, not an outboard DAC) it really wasn't that difficult to operate. It clearly took up less space that the AURALiC VEGA that's been in my system for the past half-year, and even though its controls aren't as assessable, it didn't really matter because the Hugo is basically a set it and forget it component. The sound quality of the Hugo when used as an outboard DAC was much more important to me than its ease of use or lack thereof. Its sound quality was very similar to its sound when used as a headphone amplifier the bass was deep and very pitch stable, although it had that bit of extra warmth that belied its solid-state innards. It was able to separate instruments and voices into discrete areas within a layered soundstage, and the sound of its treble didn't have a hint of grain or other nasties that might have been present in less accomplished digital components of the past. Compared to my resident DAC it doesn't have the beefy and more complex sound that makes it one of the best mid-level DACs I've ever heard, but the AURALiC cost a thousand dollars more, and is probably about ten times larger. Its larger size most likely allows it to have a more hefty power supply, and if the Hugo was available with an upgraded power supply that could replace the smaller outboard unit it is shipped with I would bet that it could compete with the units not only costing more, but that are meant to be used exclusively for this purpose.
I only have one nitpick that I'd like to mention. This is going to be a rather short section of the review since there is only one, but its small buttons on either side of the unit are definitely worth mentioning. It seems as if the power switch is the smallest control on the unit, and it is so tiny that I suppose those with limited digital flexibly (the other digital) might have some difficulty turning the unit on and off. I suppose it is located a slight recess of the side panel to prevent it from turning on and off inadvertently when it might be bouncing around inside a case when it is in transit, but combined with its small size one could imagine it even being a challenge for those who are even more nimble than I. Also, I wish the Hugo was less expensive, but often one does get what they pay for.
