Qutest Sound Impressions

Tonality

In a word or a phrase? Fabulously detailed sounding. But then if you are a Hugo 2 owner this would come as no surprise since this is one of the key traits its DAC section is known for. Over the course of the last 2 months, it has become my ‘go-to’ desktop DAC. It sounds brilliant with just about any desktop amp I have paired it with thus far.

I would not classify the Qutest as dead neutral though. There are some subtle accents on the low-end body and treble presence that mark it as being slightly different to the Hugo 2 also. If anything, compared to the Hugo 2, the Qutest has a bit more treble focus and energy and a slightly more neutral timbre.

Vs The Sabre Sound

Compared to some competing Sabre DAC desktop units that I would definitely class as neutral or bright the Qutest is a little less on the cool side, more natural in tone, and not quite as strident the further up you go in the frequency spectrum. It is subtle at times and the choice of the amplifier may affect how much you hear those nuanced qualitative differences.

We used an Auris HA-2SE and Xi Audio’s Formula S with Hifiman Ananda for the majority of our testing. Both amps are very nicely balanced and the fact one was a tube and the other solid-state was neither here nor there. With both amps, we felt the Qutest offered a little more low-end body and lower-mids warmth than competing pairings such as the NuPrime DAC-10. We also heard a more complex and open sounding midrange with better instrumental separation and layering.

Timbre

The timbre also sounded a bit more natural to my ear when comparing the likes of the DAC-10 and the Oppo Sonica ES9038PRO-infused DAC desktop. Both of the delta-sigma desktop units sound very detailed. In particular, the Oppo gives the Qutest a run for its money in terms of instrumental separation and outright staging width.

However, it is that better body on the low-end of the Qutest that makes all the difference. There is a certain warmth or more liquid sound that just sounds spot-on in terms of timbral accuracy compared to the Oppo and DAC-10. These two can sound a lot drier, perhaps even harder in leading notes with their treble overtones. Certainly, for the DAC-10’s older ES9018 chipset, it is sharper and more clinical sounding.

Matchability

Filter Preferences

Initially, I would say the Neutral Incisive filter for the maximum amount of detail over the complete frequency spectrum. It is there you hear that little forwardness in the treble presence.

However, over the last month, I have started using the warm filter, especially with the HA-2Se tube amp. The black background it offers is just a brilliant match for the HA-2SE’s very low noise levels. Combine that with a little more warmth and just a shade off the very top end and I have possibly the ideal setting for a long-term listening session.

I tend to use this combo for heavy synth and guitar/percussion work on the likes of Daniel Deluxe, Dan Terminus, and old classics from Metallica such as And Justice For All which is a very dry recording to begin with.

Should I wish to go back to a more studied listening session I tend to revert to the Neutral Incisive which is very dynamic and resolving with Class A amps such as the Formula S from Xi Audio.

Verum 1

Amp Synergy

The beauty of the Qutest is that it works amazingly well in terms of synergy with just about any decent desktop amp you can throw at it. For those that absolutely must have balanced then no, the Qutest cannot offer that compared to the likes of the Oppo Sonica and NuPrime’s CDP-09 and DAC-10. You can up it to 3V and it will sound peppy for sure but not 8V balanced peppy such as the DAC-10 can offer.

Xi Audio Formula S

However, not all high-end amps offer balanced. In fact, with Xi Audio’s $4000 flagship Formula S Class A amp it is entirely single-ended. The makers firmly believe single-ended produced a better tone than balanced. I can’t fault them on that claim because the Qutest/Formula S has one of the blackest backgrounds I have heard to date on any system combo.

It also has a beautifully articulate sweet-sounding timbre that I could listen to for days on end. I tend to keep the Qutest on Neutral Incisive because this amp is incredibly resolving and will easily handle the detail the Qutest throws at it without ever sounding harsh or cold.

Auris HA-2SE

The Auris HA-SE you will see me mention many times in this review. This is one super quite low-noise tube amp. The best single-ended tube amp I have heard in ages with regard to clarity without noise. It also sounds super balanced with a nice analog pure sound that never sounds overly slow or warmed-up.

The Qutest takes absolutely nothing away from the HA-2SE ability and the HA-2Se allows the Qutest to really shine. That slight low-end body and natural midrange tone of the Qutest is a perfect match for the HA-2SE’s presentation. Pairing this with a Final D8000 planar or the Hifiman Ananda and using the warm filter is just gloriously easy to listen to.

Chord Hugo 2

£1,800.00

Technical

The Hugo 2 costs a bit more than the Qutest but then again, it does pack a bit more in terms of features and it also primarily targets the portable audiophile. That being said, features such as a 5V USB chargeable input does mean it can quite handily function as a high-end DAC in your system.

The Qutest lacks the amplification stage and headphone outputs, it also lacks the Bluetooth receiver. Logically, the Qutest also does not offer the Hugo 2’s X-PHD crossfeed functionality. The Hugo also has independent volume control and can dual as a pre-amp or deliver a fixed line-output. Both have the same filters with the same frequency shaping properties.

The Hugo 2 does not, however, have the ability to switch the voltage of the analog line-out so it is fixed at a rather high 3V. The Qutest has much more flexibility in this regard with its 1v, 2v, and 3v options. Some might also prefer the Qutest input and output socket designs as they are less recessed and further apart than the Hugo 2. The Hugo 2 will not work as well with wide barrel RCA plugs and coaxial cables due to the recessed design and proximity to each other.

The final difference is the BNC coaxial sockets. The Qutest’s BNC connectors make it a logical choice to hook up to Chord M-Scaler in any desktop system. The Hugo 2 does not have a BNC system being limited instead to a single Coaxial input.

Performance

Remarkably, the Hugo 2 and Qutest do not sound exactly alike despite using the same DAC design. Just to temper excitement, these are very nuanced differences. Working both DACs from the same source tracks, same laptop, cables, and analog amp you can detect where each deviates from the other.

Using the Auris HA-2SE, which is where the Qutest has been tethered to for the best part of 2 months, the Qutest sounds a touch cleaner, especially in the upper mids and lower treble. The Hugo 2 has a slightly wetter low-end with a little more mids body but only very slight. You can hear that body also in the male vocal presence on the Hugo 2 which sounds the tiniest bit richer and further forward.

The Qutest seems to be gunning for total neutrality in instrumental positioning with perhaps just a slight bit more top end emphasis. Its vocal presence is also more neutral in both position and tone. You could argue that the Qutest is marginally the more lively of the two as a result with the Hugo 2 slightly the more natural sounding. Other than that resolution and imaging on both DACs are more or less identical.

NuPrime DAC-10

€1,495.00

Technical

The DAC-10 is aging a little but still a very impressive DAC/Amp and still priced at 1500 EUR which is more than the Qutest. Of course, you are getting a wider range of features in a larger box, not least the balanced and single-ended headphone amp stage and a fully balanced XLR DAC/Amp system.

The DAC itself is delta-sigma with a last-gen ES9018 Sabre chipset which is still quite competitive but not as future-proofed as the Qutest FPGA enabled decoding capability. The DAC-10 tops out at DSD256 and PCM 24BIT/384KHz compared to the Qutest’s 32BIT/768kHz and DSD512 potential.

The noise numbers though are competitive with a THD+N: < 0.0003% which is just marginally behind the Qutest at 0.0002%. The dynamic range for both is also excellent with the Qutest at 117dB on a 300Ω load and the DAC-10 at 115dB on a 600Ω load. In all, a very well implemented design on an older chipset from NuPrime.

Like the Qutest, you also have a measure of line-out voltage control on the DAC-10. On the unbalanced analog line-out you can switch from 2v to 4v should you require it and on the balanced you can switch from 4v to 8v which is quite a jump. The Qutest is a little more nuanced in its 1/2 and 3V settings and only has an unbalanced output to amps. The DAC-10 can also offer pre-amping with its own independent volume and remote control system.

NuPrime DAC-10

Performance

Both DAC’s aiming for neutrality but the difference between both of them using the same source tracks, PC and amp (HA-2SE) is quite obvious. The DAC-10 has a colder leaner timbre, less instrumental separation, and thus sounds a little flatter and more clinical to my ear.

The detail is excellent, no issues there but it is delivered dry and less natural sounding with that ES9018 lower-treble emphasis that can test you if paired with a bright amp. The Qutest has the more low-end body, slightly more liquid in timbre, and a warmer lower-midrange performance. It also has a better treble body as well as a more coherent and less cutting treble sound.

As a result, you are not drawn into the treble peppiness with the Qutest quite like you are with the DAC-10. The Qutest allows you to enjoy or at least perceive to enjoy the full spectrum of instruments both low and high hence that lack of flatness I spoke about originally.

Oppo Sonica

$799

Technical

Too bad Oppo went the way of the dodo recently because their gear has been top-notch this last 10 years. The Sonica DAC got our award last year for the best DAC of 2017. The price tag matched with the ES9038PRO delta-sigma integration was by far the best value to performance ratio yet seen with the latest gen Sabre TOTL DAC chipset.

The Sonica is set up a little more like the DAC-10 than the Qutest but without the amp. It will operate as a pre-amp so you can vary between variable and fixed line-out signals to your amp of choice. It does both balanced and unbalanced analog outputs and accepts USB, Coaxial, and optical inputs though no BNC.

The decoding is on par with the Qutest with a capability of up to DSD512 and 32BIT/768 kHz PCM. Its noise (THD+N) numbers are marginally less competitive at 115dB compared to the Qutest at 117dB. The output voltage parameters of the Sonica are fixed for a line-out at 2V unbalanced and 4V balanced whereas the Qutest can be adjusted between those 3 settings.

A big difference though is the Bluetooth and wireless options inside the Sonica as well as the Android app integration for remote control. You can stream Spotify and TIDAL via the Sonica. The Qutest remains a wholly wired traditional solution.

Oppo Sonica

Performance

Both the Sonica and Qutest are aiming for that same relatively neutral and detailed ground but they do have some differences in their presentations.

The first is the general timbre of each. The Sonica is a touch brighter to my ear which seeps into the instrumental timbre a bit more than the Qutest. As a result, the Qutest has the more accurate sound, slightly less digital in comparison and perhaps a little wetter or smoother.

The Sonica will come across as the livelier of the two because of the slightly greater treble emphasis so you might be drawn a little more to high pitched synth runs, cymbal crashes and guitar plucks with its clean attack and short decay. The Qutest will sound the smoother of the two, with a more natural-sounding treble but still fairly clean overall and very even sounding in terms of its harmonic balance.

The Qutest also has a bit more bass to lower- mids body than the Sonica. The Sonica is a little cooler of the two and slightly leaner in the mids. I tend to be drawn more to midrange dynamics and vocals with the Qutest compared to the Sonica’s lively top-end.

One interesting thing with soundstage is the width and separation you perceive with the Sonica’s presentation. Perhaps due to its lively treble presence but it sounded just that bit wider and taller. The Qutest just pulled it back ever so slightly in favor of something I felt was more natural to my ear but not quite as expansive sounding.

Chord Qutest

Our Verdict

Gosh, what is there not to like about the Qutest as a pure DAC? Whilst not a total carbon copy of the Hugo 2’s DAC signature it still resolutely detailed and fantastically natural sounding with just about any amp I can throw at it.

Sure, it does not have all the bells and whistles of desktop DAC’s such as the Oppo Sonica or NuPrime’s DAC-10H. If you want something balanced with huge dollops of voltage then these two component units will give you that and then some. If you want wireless and streaming with your DAC then the Oppo is one of the best-priced choices on the market still to this day in my opinion.

However, on pure sound quality alone it is the best DAC I have heard to date this year. I guess I should not be surprised at that given my thoughts last year on the Hugo 2’s fantastic decoding capability.

      It is a little warmer and beefier and of course, has limits on resolution compared to the USB but if you are not working super hi-res stuff then its perfectly fine.

    UPD: after loooong listening session. DSD in Quitest correctly play only in D2P and white filter! all ther rest will destroy compleatally imaging. I did not test native DSD, it works only only from Windows.
    If you want to hear what i mean, you need to listen 2nd track Mourning Grace form Patricia Barber – Cafe Blue in DSD. I will hear it’s perfect sounding ONLY in D2P mode and white filter… the rest will destroy the scene.. filters and DoP. I hear it wery well from headphones. Good to test your gears and hearing ;)
    Let me know what you heard.

    Yes. I know it’s not common but wish to hear this DAC directly. Apperantly it’s drives well my Grado (32 Ohm) HP1000, RS1 and GS1000i. I just introduced atttenuation in line (Alps pot used).
    PS Sad, I wrote huge reply here (detailed comparison Hugo TT with QUtest, and Hugo2.. and why Hugo2 fail to me),but platform somehow not Posted it afterall (
    some bug.. it always suspect me for spam (

    Yes. I know its not really common to do. But as i said, was really curious to hear this DAC directly. And apparently Qutest output stage is capable do drive directly my Grado (32Ohm) RS1, HP1000 and GS1000i. I am simply introduce attenuation (Alps pot). SOunds very well. So, DAC itself is shine. Means nay good amp will do excellent pair, so everybody can do they system at the moment source SQ is confirmed. Which us the case here with Qutest. Such a particular gem from Choed! You can easlily connect any powerbank to feed it, even I did not hear much diferance in compare to the stock adapter. And I compare sound quality directly by extencive AB to Hugo TT. While during this direct comparison Hugo2 fail, Qutest demonstrated all changes and differents in compare to first Hugo. After Hugo2 listening i was a bit sceptic in regards as step forward. But now I can confirm new DAC from Chord sound very intresting. I still cant say which version 1st or 2nd is better. They are different and I like both. Classic HugoTT has wider sound image but a bit too airy less defined in compare to Qutrst. Still very relaxing and enjoyable it has better atmosphere but sifter. While Qutest (new DAC) has still very nice deeps but a bit narrow image wide. Still good vertical and depth scene image. But in compare to classic Hugo it more detailed, transparent with better defenition. You can here its better in music with many violins in stage 3-4-5.. Its so obvious how you can much better seoarate and here each of them. Maybe lesse relaxed listening in compare to first generation Hugo TT DAC, but very engoyable to here every instrument in the stage.. Last thing to include is a BASS, but it fits what is said abive. Hugo TT more extended and smooth, more airy. Qutests more deifend, has more impact, more articulated and more textured and a bit more punchy represented. Again less relaxed. It;s really of quetions for individual preferance and particular system. At the moment love them both. PS confirmed in both Hugo2 and Quterst if you have DSD, D2P need to be used, there is something strange with DoP realisation. I do hear clear diffarance.

    this is exactly why i went for Qutest after Hugo2. From Hugo2 I heard capability of the DAC but get felling the headphone amp stage of Hugo2 do something that i dont like let’s say. But was very courious to listet directly to new DAC. And Qutest confirmed my expectations. What a wonderful dac. I connect my grado directly to RCA out with smal attenuation. What can I say… Bravo Chord! Very good. And I found green filter the best for me.

    100% agree! Hugo2 compleatally distroy immaging and scene layering. Scene is wide but very thin.
    Get qutest and was write so nice dac! ALl is there and very nice imaging and deeps.

    Stay away from DoP with Qutest or Hugo2 ;)
    Use D2P.. differance is night and day! DoP kills all deeps an scene imaging.

    Not exactly. Rob Watts said if the DAC section is basically the same, the output stage has a different design. That could explain the slight differences between Hugo 2 and Qutest.

    That’s the interesting thing Jorge, the DAC inside the Qutest is the same as the one inside the hugo 2 but they sound slightly different. I wonder if the Oppo 205 sounds slightly different to the pure DAC Sonica?

    I thank you for this excellent informative review. Indeed it’s a very good DAC.
    I just wanted to share with you that in my system I find the Qutest brighter than the Oppo 205, which I think uses the same ES9038PRO as the Sonica.
    Furthermore, with Linux, and I imagine also with Macs, DSD via USB is only available through DoP.
