AURALiC tease Aries G2 streamer, Vega G2 DAC & more

  • What’s the frequency, Kenneth? On the global audio show circuit, I encounter AURALiC’s Xuanqian Wang more than any other manufacturer: in Denver, in Las Vegas, in Los Angeles, in Hong Kong and in Munich. And on each and every occasion for the past three years, I have asked Wang two simple questions: 1) When will we see a MK2 Vega DAC?; 2) Will it come in black? Wang’s reply was almost always, “Awwww, c’mon – why do you want black?”. Hats off to the man for tolerating my repetitive approach to hifi journalism.

    In April, I followed up with Wang on the recently announced Lightning DS v5.0 Beta. An update that brought with it a new web interface. Here’s how that email exchange played out:

    JD: I only see a way to setup an AURALiC device. Does the web interface allow us to choose songs and control playback? Or is that still to come?

    XW: The web control interface is for device setup only, which enables non-iOS user to setup the unit with full function. Since Lightning DS is only available on iOS platform, non-iOS user still need to use 3rd party software for playback control. For Roon customers, they can access to web interface directly from Roon software through a button, which means they do not need to know or input IP address manually in web browser.

    JD: With this choose-your-own-software approach, the open sourcing of the web client’s development and Roon landing on the Mini, does this mean you’re relaxing a little on which software you recommend end users use with your hardware?

    XW: We never restricted customer’s choose and the company always listen to what our customer want. Our platform is getting more and more stable so we believe it is the time to add more features now. The ARIES MINI only has half system memory comparing to its big brother so there were always some limitation.

    JD. You’re going your own route with MQA file handling. What motivated this move? And what can you tell us about your filter? I presume it’s only applied to MQA content and that a different filter is applied to normal PCM? What are you trying to achieve soundwise with these filters?

    XW: AURALiC’s goal for MQA playback is to let our customers get the best possible sound from their existing equipment without need to purchase anything and that experience has to be free of any charge. The filters we applied to MQA file playback is a special optimised minimum phase filter with minimised pre-echo and ringing; it is quite similar to our upsampling filter but with some differences. We have already heard back from existing ARIES MINI customers whom tried the 5.0 beta firmware with MQA content and they really like the improvements we bring here. For customers who have already invested in a MQA certificated DAC, they can have an AURALIC streaming device not change the signal and have it sent to the DAC directly – they also need to disable the volume control function inside Lightning DS to make sure the MQA signal is unaltered.

    JD. You’re about to introduce a new version of the Aries? What can you tell us about its tech specs and other features?

    XW: Do I still need to answer this question?

    As it turns out, no.

    According to the man himself, Wang works (almost) every day from 7am until midnight. This explains his crazy fast email response time. On one occasion, a reply arrived at 3am. This wasn’t the Berlin-Beijing time difference at work but Mr. Wang working into the wee hours.

    Wang’s show preparations are thorough. The company’s most recent press release, one that arrived a few days ahead of the Munich show’s kick off, included five (count ‘em) multi-page documents. I would have tackled them there and then but Wang had tipped me off that more was still to come. “Wait for Munich,” he said. OK.

    Unsurprisingly, AURALiC’s Friday morning show and tell felt more like an intensive training course than a press conference. For a full 45 mins, Wang’s Powerpoint presentation took us deeper into the company’s four new ‘G2 series’ products.

    Chief among them was a second generation Vega, dressed in black. Sitting on the shelf above was a second generation Aries. It too wore black. Had our man from China run my quest for black hardware into the end zone? Touchdown!

    Time to disseminate: Readers who like to know about the chip are advised that the Vega G2 (US$5600) utilises an ESS DAC chip, custom made for AURALiC and not an off-the-shelf model. Readers are cautioned that a DAC’s performance also falls to its power supply, output stage (here, AURALiC’s ORFEO) and noise shielding.

    To wit, running at the heart of the Vega G2 is AURALiC’s Tesla platform: a Quad-Core A9 chip, 1GB DDR3 RAM and 4GB of storage, all running at 25,000 MIPS. According to AURALiC, that makes it 25 times more powerful than first generation Vega.

    This extra grunt allows the Vega G2 to deliver Roon Ready / Lightning DS network streaming. Gapless playback, memory caching, bit-perfect multi-room sync and upsampling all show up to the Lightning DS party. Ditto Roon.

    One of the biggest criticisms levelled at the original, superb sounding Vega was its lossy digital control. Well, no more. The G2’s attenuation comes from a passive resistor-ladder control that draws zero current when set. This has in turn allowed for the inclusion of an analogue input (hello turntable/phono stage) on top of the usual array of digital inputs: USB, TOSLINK, coaxial and AES/EBU.

    A pair of 72fs Femto clocks, one each for 48kHz and 44.1khz sample rate familise, keep jitter to a minimum. From the press release: “The 72fs Femto Master Clock is just as quiet as it is accurate, with an extremely low -169dBc/Hz of phase noise and a 100Hz offset noise level of only -118dBc/Hz, thanks in part to its low-noise 3uV dedicated power supply.”

    Also keeping the jitter-inducing EMI to a minimum is the galvanic isolation of CPU, Femto clocks, DAC chip and analogue board as well as the subdivision of 1) processing circuit, LCD display, network interface and 2) DAC, Femto clocks, analogue board between two ‘Purer-Power’ linear power supplies.

    Those hoping to ditch their NAS by hooking a USB storage device directly into the back of the Vega G2, or by installing a 2.5” SSD/HDD into its undercarriage, will need to look to the Aries G2 network streamer (US$3900) instead.

    Not only. The Aries G2 also promises to take the Vega G2’s sound quality to the next level by way of a still more powerful Tesla platform: “The AURALiC Tesla G2 Platform is the revamped heart of the ARIES G2, and it packs a processor that’s 50% faster than the Tesla G1 platform, with twice the system memory (2GB) and data storage (8GB) of the previous generation,” reads the press release.

    The Aries G2 also sees AURALiC once again make use of sub-divided ‘Purer-Power’ supply, galvanic isolation of key circuit areas and dual Femto clocks, one for S/PDIF outputs and one for USB.

    However, the big story here is the Lightning Link that joins Aries G2 to Vega G2.

    AURALiC’s press release explains: “Lightning Link is a low-jitter, bi-directional 18Gbps coupling that takes advantage of high-speed HDMI-type hardware connectors.”

    Crucially, and unlike I2S, Lightning Link is bidirectional, allowing for clocking information to move from Vega G2 to Aries G2 and control data (e.g. volume control) to move from Aries G2 to Vega G2. Linked devices will appear as one in AURALiC’s Lightning DS control app.

    Don’t pull out that credit card quite yet. The Aries G2 and Vega G2 will only be available from September onwards.

    In the wake of their AXPONA debut in April, some have likened the appearance of the ‘Unity’ chassis, cut from a single billet of aluminium to minimise airborne vibrations and EMI, to that of Naim’s new (ahem) Uniti series of components. Fair enough.

    However, once we factor in the similarly form-factored Sirius G2 upsampling processor ($TBC) and the Leo G2 Femto reference clock ($TBC), not due to drop until the end of 2017, things start to look decidedly dCS-like. That’s no bad thing: start with a DAC, then add the external streamer, upsampler and word clock as budget allows. Both Leo G2 and Sirius G2 can be Lightning-linked to Vega G2.

    Sharp eyes will have caught the twin 6.4mm headphone sockets on the Vega G2’s front panel. A post-Munich follow-up with AURALiC’s German office didn’t bring forth any further details. Their lips remain tightly sealed on the what and the how.

    Even if AURALiC don’t specify the world’s most sophisticated headphone amplifier, its inclusion gives the Vega G2 the functional edge over its closest rival: no, not the original Vega but PS Audio’s DirectStream DAC fitted with Roon Ready Network Bridge II. Expect to see that comparison form the core of DAR’s Vega G2 review when it drops later this year.

    1. “Even if AURALiC don’t specify the world’s most sophisticated headphone amplifier, its inclusion gives the Vega G2 the functional edge over its closest rival: no, not the original Vega but PS Audio’s DirectStream DAC fitted with Roon Ready Network Bridge II.

      Hi John, when you mention functional edge above, I was confused because the DirectStream DAC doesn’t have a functional headphone amp. Do you mean ‘value added edge’?

      • I mean functional edge – as in the Vega will offer greater functionality than the DS.

    2. Is mean that Lightning DS v5.0 without songs and control playback by web browser ?

    3. Hi John: AURALiC’s G2 sounds OUTSTANDING..
      and great feedback!

      1)..for clarification using the vega g2 streamer vs aries 2 streamer “sonicall”y.. would the aries 2 on another level?

      2) How did vega G2 sound? I haven’t seen anyone in the industry discuss the vega g2 “sound” anywhere.. or will everybody wait to report “how it sounds” after they review the product over the next 3 months?

      3) how was the industry buzz with g2 products?

      4) the other 2 products sirius g2 and leo g2 …did Xuanqian indicate how much improvement adding these 2 products?

      5) will the lighting link be an upcharge?

      6) Which XLR cardas interconnect cables was Xuanqian using with the vega

      7) lastly, if using jriver a mac book would still be necesary with external thunderbolt high capacity drives…. ?

      Thank you.

      • Steven – maybe no-one has commented on the sound because it is impossible to do so with any reliability?! Yes, Auralic opine that then Aries streamer will sound better than the one in the Vega. I believe I said that above? As for adding the other products, we just won’t know how much they’ll add until we get them home into our own listening rooms. No idea on cost of LL or which cables were being used.

        • Thank you John. Fair enough.

          Also, with the new volume control on the Vega G2.. running power amps direct to the vega would now be optimum (excluding pre amp) for all digital setup?

          How soon until you have your Vega and Aries G2 to test?

          • In my experience, skipping out on the traditional pre-amp makes for a faster, more quick-silvery presentation but surrenders some tonal mass.

            I wont’t see review units until they begin shipping to distributors/retailers.

    4. Thanks for the coverage on these Darko, much appreciated. Understand that there was no official announcement, but did you gain a sense of what the G1/G3 offering would be? Specifically, how do they see an Aries Mini replacement filling its own unique space as they revise the product line? Again, thanks!

      • No word yet on G1/G3 and I’d prefer not to speculate. The Mini will continue as an entry level brand flag waver, I think. For me, on SQ and Roon Readiness, a much better alternative to Sonos.

      • Yes – an all new, higher end model. Not really comparable with the original, either on specs or price.

    5. So the first Roon Ready device in Auralic’s line up will cost more than $3,000? Not what I’d call consumer friendly….

      • I guess that depends how much one understands of what AURALiC do Roon-wise: both the Aries and the Aries Mini are Roon Ready. Ditto the Polaris and the Altair.

    6. Sorry… It’s so hard to keep up. Everything I found in a (admittedly quick) Google search indicated that the Mini would never be Roon Ready….. If I still have the sub-$750 option available, I’m happy. But you did indicate above that the Aries will be replaced by a model costing two-three times the original. Shame that the Schitt guys are so dismissive of MQA. Now, THERE’S fair pricing.

      • You’re talking subjectively of course. One man’s fortune is another man’s pocket change. The G2 costs more because it is essentially a completely new product – only the name remains the same – and it will come up short on value if it fails to compete with similarly-priced products, not simply because you or I might not be able to afford it.

    7. Hi John: Looks like some impressive hardware !

      Any idea or explanation as to why either a “Wrd. Clk” pr conventional i2S (over HDMi or RJ-45) is not on offer ? Either have been used with excellent results.

      If the Auralic G-2 series fails to provision for existing (and even new) DAC’s, Streamers and CDP’s utilizing this digital connection will surely impact desirability and hamper sales of both the Aries-Vega G2 series.

      Have you any idea for the rationale behind this (what appears to be ) oversight ?
