Introducing Olympus & Olympus I/O - A new perspective on modern music playback

[Steve Williams]

Roon has a volume control.

I don't use Roon but will in order to test the analogue card

My preference is XDMS NSM

Someone had posted that the Olympus isn’t shipping with XDMS (although some may have access to it via the alpha testing group). In addition, currently XDMS can only access music from the internal drives, not a NAS.

that was posted yesterday and Roon as a temporary stop gap is fine with me. Just think of how many different scanners we have used with the XDMS control app. I have no problems reverting to Roon util XDMS is completed but at the moment I still prefer XDMS NSM

Steve, I tip my cap to you. I figured when you heard this you would go down kicking and scratching! With age comes wisdom...We hope!

Roon has a volume control.

Unfortunately, Roon's digital volume control algorithm seems to be lossy.

The only lossless digital volume control algorithm I know of is Leedh Processing.

To my knowledge there is no other.

It's a fascinating maths/algorithms subject.

This is one of the reasons why I chose the Soulution 760 DAC, and the fact that it's a DAC that's a bit out of the ordinary. Cyrill Hammer, Soulution's owner, is a vinyl amateur.

If you fancy reading technical documents, the white page on the site, explaining the problem, is worth a read.

It will be interesting to discover which approach Taiko Audio will choose for its volume control: digital or analogue

 

[dminches]

Using the Roon volume control is a temporary solution. No one is suggesting they use it long term.

As we are fortunate to be in the possession of an Ageto as-well I can tell you they play magically together. However we don’t have an Ithaca so that’s going to be up to you to try.

Details on that to be worked out /announced.

As all DACs have their own unique distinct character/sound signature there’s no answer to that, do you prefer MSB, Aries Cerat, Lampizator, Totaldac etc, analogous to which wine you prefer, or perhaps you prefer a specific whiskey, or just a nice cool beer.

Thanks Emile! You answered most of my questions even cryptically. Haha.

 

[MarcelNL]

a 'passive pre-amplifier', or rather a (shunt) resistor between DAC and AMP works fine. I can recommend Khozmo as one of the most neutral versions I've heard (and used with Z foil resistors).

The sonic difference between digital volume control and real colume control is quite real IME, Metrum makes volume control on the DAC possible by varying the reference current for the R2R system and that method sounds better than a passive volume control.

 

[Blue58]

my question regarding the absence of a volume control and using the analogue card and go direct to amplifier is, "how will one control volume " until a volume control becomes reality on the Olympus

I can vouch for the Khozmo, with Z Foils, and only 1 input, to work perfectly between my Extreme and SETs. Probably as simple as it gets. It uses relays rather than a pot to adjust volume. 64 x 1dB steps enable fine control.

Dear Emile, When do expect we can start using XDMS with the Olympus? June? July? August?
I believe it will be another important step up vs. Olympus running Roon.

@emile, i will trade in my Extreme server for Olympus XDMI server. Does it come with the 4T u.3 storage ? If so, will it come with the adapter for file transfer ?

I am amazed by this.

With Olympus Server, does this mean the streaming sound is better than the sound stored on the internal 4TB of storage?

Is Taiko Router, Switch, and DCD a must?

Yes and no. I can now elaborate on this topic in more detail as we spend more time running extensive tests on this yesterday.

1) The Olympus bolsters a larger degree of immunity towards network noise / disturbances then the Extreme. Do note that the network card in the Olympus is not the exact same network card as used in the Extreme, it has been adjusted to perform better running off battery power. To get ahead on a follow up question I can foresee coming up next: No this is not an upgrade for the Extreme, the Extremes total system design architecture simply differs.

2) What this accomplishes is that the DCD/Switch/Router no longer significantly impacts local file playback quality. Sound quality of local file playback is more or less the same whether we run RJ45 directly to the wall outlet connecting to the building main switch.

3) In this scenario, without DCD/Switch/Router, local file playback is significantly better then streaming from Tidal/Qobuz, and/or playback from a NAS.

4) When you add the DCD/Switch/Router, the story changes, this elevates streaming from Qobuz to the same level as local file playback, assuming the same file format, to this end we have purchased and downloaded several albums from Qobuz in a .flac format, in the same resolution as offered by the Qobuz streaming services to ensure as much as we can we're using the same files. Copying these files to a NAS connected to the Router provides more or less identical results. A small exception is streaming from Tidal, for reasons unknown that sounds a bit better then everything else here, that goes for both our 1Gb internet fiber service in Oldenzaal, as for the 100Mbit internet fiber subscription at @audioquattr . We're aware many prefer the sound of Qobuz, perhaps this varies on a global location scale ( @audioquattr lives about 50km away from here), but admittedly we simply don't know why.

5) Inevitably you may ask what happens if you remove the local storage from the Olympus. Undeniably this does make a small difference, if you are hunting for the last ~2% of ultimate performance, removing local storage and using Tidal/Qobuz/NAS with DCD/Router/Switch as your file source, does ultimately produce the absolute best Sound Quality here.

As a footnote, I would like to add we're not talking changes at the level of changing interconnects/power cords or even components here, with the only exception being streaming without DCD/Router/Switch, that has a very considerable impact. Hence my answer to the specific question: "Is Taiko Router, Switch, and DCD a must?" would be, only if you want your Tidal/Qobuz streaming to be on par with local file playback, similarly, if you have a very large library, and want to use a NAS with virtually unlimited storage expansion capabilities, at a much lower cost then internal storage, then in our opinion, the DCD/Switch/Router would be a "must" as well.

No eta on this, the priority is to get XDMS to a 100% stable beta state first on the Extreme, then we will start rewriting it for the Olympus. Do note that the Olympus will "care less" about the actual playback software used, hence although the overall lighter footprint of XDMS may produce some benefits, I would not expect this to be as major as it's on the Extreme.

 

[Taiko Audio]

Yes it comes with 4TB of storage by default, and yes we could provide the adapters on request.

Thanks Emile, more fascinating insights..!

I assume the size of the internal storage on the Olympus wouldn't matter wrt sound quality, its just the fact of it being there or not, in the form of a single drive of the type you identified / recommended?

Emile, has your testing included assessing how sound quality is affected by where the NAS is in the system and how it is powered? That is, is it optimal for the NAS to be connected to the Taiko router (as opposed to just being on the home network) and is sound quality improved by powering the NAS via the DCD?

Thanks Emile for the updates. We may need to look into fanless NAS to place in our listerning room then. Like this one.

Not sure if this has been answered already: If trading from an Extreme to an Olympus plus 'Extreme Switch + Router + NIC + DC Distributor (Bundle)' is the NIC in that bundle still needed or is it the same NIC which is fitted by default to the Olympus?

I suspect Preamp will be Pilium as well.
