Hi Stefan,

Regarding the daughterboards for the XDMI interface, it all depends on what you've ordered.

You should have a list of what you ordered in the confirmation email.

But I suppose you will get:

- the XDMI daughterboard for LampizatOr
- the analogue daughterboard (DAC)
- the digital daughterboard (AES/EBU - XLR)

But again, it depends on what you've ordered. The best thing to do is to contact the support team.

As far as USB is concerned, and according to what Emile explained here on the forum, the XDMI interface is so much superior that it wouldn't make sense to use the USB.

The Olympus is really designed around the XDMI interface.

As for the technical details regarding the USB interface on the Olympus, Emile (@Taiko Audio ) will be in a better position to answer.

A little research on the forum may also give you some answers.

Hopes this helps,

Tom, initially most people are not going to be able to use XDMI natively since most DACs don’t have an XDMI input.

So, people will have the choice of USB or S/PDIF / AES/EBU unless they use the analog DAC. USB is still a very important interface for a lot of users given the resolution limitation of S/PDIF / AES/EBU

David, (agreed on USB) so for those of us who do have the Horizon with Native XDMI, the other interfaces onboard the Olympus will be Analog Out and USB. Other than Lampizator Out from the Olympus is USB/Analog Out The Factory Default Configuration? Or am I missing something? Is AES/EBU also part of the Factory Default Configuration?

I am not sure what you mean by Factory Default Configuration. The USB output works on its own. The other outputs are daughter boards on the main XDMI board. One decides which one they want to use (XDMI, analog out, digital (S/PDIF or AES/EBU).

I understand the USB works on its own. What I'm asking is the Olympus has output choices that fits your needs. For those of us with Native XDMI our Olympus will have Lampizator Out and Analog Out. AES/EBU would be an additional charged output and not needed for those of us with Native XDMI installed in our Horizons. Unless you needed AES/EBU for the interim with a different situation...The point I was attempting to make is 2 outs are free with the Olympus, a 3rd which can be done is chargeable...

After the introductory period ends on August 1, 2024, only the XDMI analog out (dac card) is included in the base price. Additional daughter boards - Lampi xdmi or other mfg. specific card; or the spdif/AES/EBU card - are 900 Euros each.

Swapping xdmi daughter cards requires popping the Olympus or I/O lid. Only one can be mounted at a time.

Considering the loss of the introductory discount, the increase in base price, and the additional cost of daughter boards; order soon if you haven't.

Hi all, I've joined the club recently and really looking forward to replace my Taiko Extreme with Olympus.
Based on the FAQ pdf provided earlier, there is a section which specifies that during the introduction period all the 'Olympus Server XDMI' will be shipped with 'Enhanced USB Card' included.
However from the pictures posted here it looks like the USB is just the default one from the motherboard.

Can you please explain how it is?

I will for sure use the new XDMI interface with my future purchase of Lampizator Horizon, but also would be great if I still had the option with Enhanced USB card for some DACs, that can't use XDMI (majority for now).

With the Lampizator XDMI card as part of the order will I only get the XDMI Analog card or also the XDMI Digital card? So 2 cards or 3 cards in total.

Hi @StefanK ,

Thank you for your order!

The USB implementation employed in the Olympus has been changed since its announcement.

It is now indeed one of the "default" ports of the motherboard in combination with a new USB driver.

For those interested in the technical details as to why, with the Olympus, the type of noise affecting sound quality most is the type generated by current draw, aka power consumption. The way USB audio works is very unfavourable towards the ability of modern processors to save power.

The thought now entering your mind may be, why would I care about power savings? The answer is it's a critical part of modern processor performance. Processors need to save as much power as possible to be able to reach higher performance levels without overheating. To this end, processors, controllers, buses, interfaces, auxiliary devices power down all the time, up to thousands of times a second !

USB audio / USB controllers are not that sympathetic towards this concept, they attempt to either not power down at all, for minimal latency and/or to avoid dropouts / distortion, or a very bare minimum for compliancy. This also applies to the Extreme, it will use around 60 watts in idle, and about 80 watts when streaming USB audio.

The same solution in the Olympus though, with a much more powerful CPU, does not increase power consumption by ~25%, but doubles it!

Now we have been through a lot of different USB implementations, we have a full stock of modified USB cards which perform better then our original USB cards, yet still not that great due to the power consumption "issue". The best solution we found is the lowest processing overhead, maximum power savings supporting, onboard controller with a new USB driver, it adds 16 watts to the power consumption when playing USB audio, a 68% reduction, does not suffer from latency/dropout issues, and is now "pretty darn good" if I may say so

This new USB driver supports all the DACs listed in the supported DAC document on our website, but changing the DAC profiles no longer has an appreciable effect, and thus can be ignored.

Good evening Emile (@Taiko Audio ) , good evening everyone,

I've just realised that there is a missing information.

If I'm not mistaken, the information is neither on the forum nor in the documentation.

What is the impedance of the XDMI digital daughterboard?

75 ohms or 110 ohms?

Cheers,

Thomas

AES/EBU is 110 ohms, SPDIF 75 ohms. But you can safely ignore that, the better quality connector and/or cable will sound better, regardless of its specified impedance. Without knowing this for a fact I would not be surprised if most audiophile cabling does not meet these impedance specs, and they don't need to, nobody will know

Yes until the "DISCOUNT" ends..

Not true, at least if we are to believe several manufacturers of RCA connectors and or RCA terminated 75 ohm cables:

Thank you Steve
It's good to know someone fixed this issue over past few years.
I was looking for 75ohm RCAs few years ago and was forced to switch to BNC instead .

I also got a confirmation of Olympus landing from the same Friend I believe.

here's a first tickler. I have more but I will wait for said person to post some thoughts tomorrow.

I am hearing almost limitless music space without boundaries. As if I was free falling from the clouds of sound

On USB ,it is a game changer and on XDMI it is more like vinyl.

I'm drooling just reading that

Sounds great but I could do without the vinyl comparison.

Shipments may be way late but having read this all I can say is "Kudos, team Taiko.....Emile, you are the king of digital reproduction"

steve williams · Tuesday at 6:06 PM

not for me.......to me it is a tribute to where Taiko has taken the threshold of digital music. Dare we say the barrier has been crossed
