lentille Posted December 4, 2017 Share Posted December 4, 2017 Holo Cyan - DAC+Headamp impressions With the new Holo combined DAC/headamp now formally announced and pre-orders being taken, first deliveries are expected in a few weeks. So time to start a separate impressions thread just for this product. This is for impressions not for discussing the benefits of DSD ! This is essentially a new version of the Holo Spring designed for headphone users - something I have been waiting for. I don't own a Holo or have any association with them but have been aware of them through very positive user reviews. The Spring contains 2 ladder DACS - one for PCM input and one for DSD. With theCyan, the first model being released contains 1 ladder DAC and 1 headphone amp instead. Essentials This first model contains only the PCM R2R ladder DAC - this will play your normal redbook and much higher resolution files and it will convert DSD files (up to DSD 256) to PCM files for playback - as many (most?) DACS claiming to be DSD capable do. The Spring and a minority of other DACs do native DSD (better for the purists and I do have one of those other non-holo ones) and there is a later version of the Cyan coming out for this. • Inputs are : -USB (isolated from ground) -Coaxial (RCA) -Coaxial (BNC) -AES -Optical I2S the HDMI interface (DSD256) USA and IS2 support DSD DOP mode DSD256 andall other digital inputs support DSD DOP mode to DSD64) • Outputs are: Fully balanced XLR and RCA output, and balanced headphone output using 4 pin xlr Full size 1/4 inch single ended headphone output Other points of note: • The clock is a still a femto one but not quite the same as in the Spring, whilst the USB input has apparently been upgraded compared to the USB input on the Spring. • Offers oversampling and non oversampling modes • The case is smaller than the Spring being 281 * 260 * 55mm or 11* 10 * 2 inches • The new fully balanced headphone circuit • Ability to select either low impedance or high impedance for the headphones and to change this easlily • The remote control functions include volume as well as switching between low & high gain to satisfy users of IEM's through to tougher to drive full size audiophile headphones. • Jeff the lead designer has commented that unlike other integrated units where the headamp has been poorly regarded he wanted to build a decent headamp inside. • Price - ~20% cheaper than the Spring but to be confirmed on a country by country basis . Kitsune will no doubt update for the USA and others for Europe and elsewhere Sydneysider Link to comment

giordy60 Posted December 9, 2017 Share Posted December 9, 2017 two questions : is the DSD version only nos? how do you manage a PCM signal? sistema: Server HDPlex (i7-6700-WS2016) HQPlayer con Ramdisk + HQPDcontrol > Macmini (roon core+Qobuz) o HQPlayer Client + Qobuz > HDPlex NAA (celeron G1840T-WS2016) NAD con Ramdisk, o miniPC Fitlet con immagine di Miska > Denafrips Ares2 , SPLvolume2 > Monitor KH+sub Link to comment
trybeingarun Posted December 10, 2017 Share Posted December 10, 2017 It looks like both the versions support DSD and PCM. It's just what you choose to support natively vs what you choose to convert. Jimi_Zine 1 Link to comment
giordy60 Posted December 10, 2017 Share Posted December 10, 2017 another doubt: on the European site there is the cyan with the remote control ..... but has or not a volume control? sistema: Server HDPlex (i7-6700-WS2016) HQPlayer con Ramdisk + HQPDcontrol > Macmini (roon core+Qobuz) o HQPlayer Client + Qobuz > HDPlex NAA (celeron G1840T-WS2016) NAD con Ramdisk, o miniPC Fitlet con immagine di Miska > Denafrips Ares2 , SPLvolume2 > Monitor KH+sub Link to comment
Popular Post Bimmer100 Posted December 14, 2017 Popular Post Share Posted December 14, 2017 Some of the specs are incorrect at the beginning of this thread. The dsd version can do dsd512 native and Hdmi i2s Input up to dsd512 native both dacs have src. Both have NOS or OS modes. dsd version does not have headamp since dsd cannot do digital volume control. we have a third version for the person who wants it all. The enthusiast edition is based on a Cyan pcm version with headamp but also a dsd module is shipped. It can be easily swapped and the he dsd module has internal firmware that will automatically disable the onboard headamp so iit won’t damage hearing or headphones. Also this version will have some nice kitsune badging for volume knob and the remote control. for those who keep asking.... all three versions have a remote control included and December has special introduction pricing that is free shipping and 10% off retail pricing. Enquirer directly to kitsune contact for for special bundle pricing to save more. another specification to update. The Cyan is a 28bit resistor ladder Dac. And the DSD version is NOT an r2r Dac. Same goes for the dsd side of the spring Dac module. The Architecture for he dsd module is very specific type of resistor ladder Dac and not to be confused with traditional old design referred to as r2r. The dsd module is highly optimized for optimum native dsd output. There is no conversion to pcm like some might assume. It’s pure dsd to analog conversion.

Hi Bimmer100, So, I suppose the DAC between PCM vs DSD versions are bit different. I haven't read any impression on DSD version yet, of which I'm interested. Can you please share a little about the sonic characteristic of DSD version? I'm also interested if DSD version XLR outs have lower voltage than PCM version. The spec on your webpage was not clear to me. Thanks. Jimi_Zine 1 Link to comment
trybeingarun Posted December 16, 2017 Share Posted December 16, 2017 Is there any impression about this dac esp. comparing it to the Gumby? Link to comment

The 28 bit ladder for PCM should be impressive. Any idea of the actual resolution delivered? The number of bits only matters with hi-res files. The headphone amp does not fit my use. Having a PCM and DSD dac chip does. The Cyan really appears to have some great features. Jimi_Zine 1 2012 Mac Mini, i5 - 2.5 GHz, 16 GB RAM.

PeteG Posted December 17, 2017 Share Posted December 17, 2017 Question, I use my dac's for speakers (2ch) Is the Cyan DSD more suited for headphones. Mac mini 8gb ram w/SSD/Mojo Auido Joule III -> Yggy -> W4S STP-SE pre Sage 1-> Nord One Up amp -> SP tech Continuum 2.5 Link to comment
Jimi_Zine Posted December 26, 2017 Share Posted December 26, 2017 Pete, no, please read above (Bimmer100 is one to take particular note of), or in short PCM version - Has headamp with volume control DSD version - Has no headamp and no volume control due to way (native) DSD worksFor speakers, either DAC will work but if you want native DSD go DSD verion, if you want native PCM go PCM version Remember with HQ Player you can convert in the computer, so for instance you can take redbook or high res PCM and convert it to DSD (128 or 256) in the machine then send that DSD signal to the DSD Version of the Holo Audio Cyan which will play it as is with no oversampling (NOS mode), or you can just send beautiful native DSD tracks to it and play them natively (with no PCM conversion at all) using NOS mode again. Capiche? Link to comment
Jimi_Zine Posted December 26, 2017 Share Posted December 26, 2017 Definitely interested in DSD Version impressions, many DACs can reproduce native PCM very well, look at Metrum Acoustic DACs for instance, what makes Holo Audio special is their DSD, Spring and hopefully now Cyan... To illustrate, read the Spring's glowing review in Audistream (March 2017) - https://www.audiostream.com/content/holo-audio-spring-dac-level-3-kitsune-tuned-edition Link to comment
semente Posted December 26, 2017 Share Posted December 26, 2017 For someone with a music library consisting mainly of Redbook files (classical music), is there a technical advantage in choosing the DSD version over the PCM one?

I'd be upsampling with HQPlayer. In my experience, the main reason is sound preference. If you like the sound of upsampled DSD512 sound (many do) you'll want the DSD version. PCM DAC has a number of additional features, such as volume control and headphone output that make it a more feature-rich version. With Holo Spring DAC (as well as with other DACs I've tried), I prefer upscaling to DSD512 for vocals and with smaller jazz groups. There's just a little bit of quality to the sound that makes voices sound more natural to me, more authentic. OTOH, I prefer PCM for large-scale classical orchestral music. Bass has more impact, the sound is fuller, it's... I don't know of a good way to explain this... PCM is not as subtly brittle as the sound I get with DSD. Mind you, this difference is very minor, but when I listen for it, I hear it. Perhaps it's my choice of HQP filters, or maybe it's my imagination (measuring frequency response, I don't see any differences between upscaled DSD and PCM). If someone was to ask me to choose between keeping just DSD or just PCM (all else being equal), I'd probably keep DSD. But sometimes I do find recordings where PCM sounds better, so I think I'll keep my Holo Spring DAC. Although, a volume control and HP output might almost be enough to convince me to go the other way! semente and Jimi_Zine 1 1 -Paul DeltaWave, DISTORT, Earful, PKHarmonic, new: Multitone Analyzer Link to comment

I doubt that I will be able to upsample to SDM512 (or even 256) with my old '09 MacBook Pro and this may end up being the deciding factor.

GUTB Posted December 27, 2017 Share Posted December 27, 2017 Okay guys, DSD version first impression out of the box playing some of my reference tracks. SERIOUS WINNER! First impressions, off the cuff going by memory alone: wider soundstage, instruments image deeper/larger with more space between them, increase in micro-detail, better harmonic structure. Sibilance is gone. Changing DSD rates does cause popping. DSD512 works through Roon + HQPlayer with no problem at all using the signed drivers on the Holo website on the Cyan product page. Thank God. Is NOT detected by my PPA USB v3 which is annoying because I have to feed it from a lesser motherboard USB port. But that happens a lot so I need to troubleshoot it. Jimi_Zine 1 Link to comment

HQ Player produces a tick at the start of a DSD track, and the DAC picks up on this as signal, good grief. I would return the device as unacceptable performance issue. Maybe Holo used Jriver, that player has the tick under control. lmitche 1 AS Profile Equipment List Say NO to MQA Link to comment

twluke Posted January 3, 2018 Share Posted January 3, 2018 On 1/1/2018 at 10:12 PM, Jimi_Zine said: Any more impressions? Here is my impression. The Cyan (DSD only) was delivered on Dec 28 last year and I started to prepare the cables and connectors necessary for I2S/DSD connection to the DAC via HDMI including minor soldering works. After that I’ve been listening to this DAC for more than 36 hours confirming that the Cyan-DSD is perfect in playing DSD512 sources upsampled by HQ player (via Roon). It conveys the full extent of information resided in the sound source revealed by HQP probably with least modification thanks to NOS and I could enjoy hearing this beautiful sound from Cyan. The sound stage is extending widely enough, covering high to low without edge. This is just wonderful. During the last month, I was busy in setting up Buffalo IIIse Pro DACs (9028pro and 9038pro) from Twisted Pear Audio and has been enjoying their superb quality of playing DSD512 sources via the same HQP. I can not say which would be better, Buffalo IIIse pro or Cyan, but as a DAC for the simplified use like DSD only, I can say the Cyan should be definitely the winner if you are not a serious DIY user. BTW my serial connection to the Cyan for DSD512 play is shown below. Sources: FLAC files via Roon, transferred and upsampled to DSD512 by HQP. Transport: Twisted Pear Audio’s Hermes/Cronus boards with a linux system as NAA for HQP (running on a Beaglebone Black with a Debian kernel with Botic driver for I2S/DSD connection) LVDS: Teleporter from TPA for I2S/DSD connection I2S-HDMI converter: a PCB board using DS90LV047 chip.
