Specifications:

-Chassis machined from solid copper block
-Size 160*160*40mm, weight 10kg
-1 DC input, 6 DC outputs, 2 unfiltered (pass through), 2 default filters, 2 (differing) alternative filters
-DC connectors: 2.5mm inner diameter, 5.5mm outer diameter, 11.3mm length (same as the switch and router)
-Maximum current capacity 10A, maximum input voltage 25V, voltage in = voltage out, so this would typically be used with a 12V LPS to power multiple 12V devices.

This is a very recent discovery / development as we were working on addressing noise issues associated with wifi access points. Although DC power supply filtering is something we obviously have years of experience with, zooming in on specific aspects of noise, and the way they affect sound quality took an interesting turn with investigating noise generated by devices which are not designed with sound quality in mind. For example the discovery that the degradation caused by wifi noise is in fact not dominated by the airborne / radio function but by it's interaction with the supply it is powered with and how that in turn affects and the mains supply, which powers our entire systems, gave us a different perspective to investigate.

We started analyzing these noise spectra and started designing filters to specifically target this type of noise, only to discover that this is a limited solution, as the supply powering the device is a big part of the equation, to make matters worse, different designs interact differently, with rather dramatic differing effects on sound quality as a result, keep in mind this even applies to a wifi access point which is only connected to the mains, as the connection on the output side of the device is airborne...

While testing a variety of power supply designs and various filters on wifi access points we started including the switch and router which sound quality performance, both being extremely low noise designs, are vastly dominated by the noise generated by the supplies powering them. The switch and router in fact perform better being powered by a single supply in stead of dual power supplies, simply because a 2nd power supply, even a very low noise linear supply, produces more (interacted) noise then the switch and router combined, additionally, when you connect the switch and router with the lowest noise producing option, being a DAC cable, there's a direct/common ground between the 2 devices, which is unfavourable if being "modulated" by 2 different power supplies, simply put, one shared ground is better from a noise perspective, taking into account the very low current draw of both devices. Still the switch drawing 100mA is an unavoidably lower noise device then the router which draws 500mA and which performs more processing. Hence there's a benefit "isolating" these 2 devices from each other while maintaining a common "ground" and reducing total setup noise by using one power supply.

On to the filters. Each of these provide over 80dB of additional noise filtering. Something I wish to add is that each of its 64 parts has been selected by ear, some are exotic and costly, like Duelund capacitors, and each of these have an effect at this level, just a small anecdote of what is involved and how much actual listening went into designing these. We have 2 default filters which we consider to be neutral sounding, they don't change the sound, they just (significantly) improve upon what's there. The extend to which they do that even caught me by surprise, it's far from subtle, perhaps as much as a 20% improvement on the whole package. However, there's more to this story, when I write they don't change the sound from neutral, that is in fact not true, that is referenced to a battery supply I consider to be neutral, the story changes when using different power supplies and when mains "quality" differs. For that reason we included 2 alternative filters allowing you to tune the sound towards getting a neutral balance with varying power supplies and mains conditions. Alternatively you can divert from neutral to taste. These alternative filters allow you to "tune the sound" towards a darker, fuller, more expansive sound, or to a brighter more incisive, and therefor a subjectively more detailed sound.
“Hence there's a benefit "isolating" these 2 devices from each other while maintaining a common "ground" and reducing total setup noise by using one power supply.”

This is precisely the benefit of a Shunyata Denali or Everest. Each device is isolated from the other yet shares a common ground (especially with ALTAIRA).
I’m not sure the Taiko distributor offers any real advantage in such case?
If the Switch and Router sound great with a “wall wart” each, then surely two LPS will be great, and connected to a Denali/Everest, we should not need the DC Distribution as well?
I’m a bit confused, to be honest, as the original direction was that a wall wart was good enough for the Switch and Router.

I guess it all depends on what you consider good enough :oops:

“For example the discovery that the degradation caused by wifi noise is in fact not dominated by the airborne / radio function but by it's interaction with the supply it is powered with and how that in turn affects and the mains supply,”

It’s interesting because I discovered the opposite recently. The noise from the wireless signal from my Eero 6E was definitely noticeable through my speakers, as background noise. I enclosed the Eero in a wooden box (Oak) and noise floor dropped! The signal is strong enough to still be useable by the required devices.
 
put it between the access point and router .
never between the Taiko switch,
To put a high end switch like telegärtner m12 between (dirty) router and wifi access point seems a bit …. advanced?
This switch would only deal things wifi - so a less advanced switch might do?
Of course it should not introduce dirt by itself.
Would a passive device like Delock or Emosafe galvanic isolators in this place be of any help to fight wifi access point gremlins?

A question to the ones with a big vinyl setup: When you say that digital with the latest Extreme is sounding so good - even like musicians are in the room with you - and at the same time digital is still not even close to vinyl, I‘m wondering what qualities are still missing in digital with the Extreme as of today that a high-end vinyl setup delivers?

i believe that the observation made by emile was primarily related to the Extreme's immunity to airborne radiation, which should not be surprising given the level of shielding we see in the extreme (and now in the new NIC as well), for the switch and router as well which are virtual Faraday cages!

i suspect what you were hearing was some other part of your system acting like an antenna and/or rectifier.

Desparately trying to avoid the battery supply cost, I would need
- a linear power supply for Taiko dc distributor feeding T switch (and router)
- a second linear power supply for the dirty router
right?
Why do you feel you a need a LPS for the dirty router? It will be on the other side of the Taiko Router, so what difference will an LPS make?
 
My understanding is that there will be an interesting run out of either of those approaches:

a) add a wireless access point to clean side, but then large current draw and complex interactions with power supply

b) add an iPad with Lan to clean side, but then you add a copper cable and we know there will be a sound tuning effect (for better or worse)

c) control XDMS via port forwarding with iPad/Laptop on dirty side, but then latency plays a role

bets are open, any takers? :)
i have a small preference for (b) at the moment in terms of setup, I don’t mind too much one extra cable.
Ugh. I had not realized that the wireless access point could not reside on the “dirty” side of the network. I don’t have a wired connection to my main router - I use Eero 6E ‘satellites’ which wirelessly connect to the main router. This would mean that I would need 2 Wifi access points, which doesn’t make sense (especially given that the wireless sound waves definitely add noise to my system).
I guess (b) is the best option then, but you need to hard wire the iPad to the Router?

Don’t think so.

My point is that a Wifi router in the room adds noise through the wireless sound waves, not only through the AC lines. For the best sound quality, we really should have no wifi in the room, period.
It would be great, for those of us who never stream, to have a solution that is hard-wired to the Extreme. The Switch/Router/DC Distribution is kind of overkill If the only reason you need a network is to control playback!

i have to respectfully disagree. i only play local WAV files and the switch made a HUGE difference here. overkill? not here, it is a necessity.

as for your first point, of course the RF signal from a wifi router can add noise to a system, i'm just suggesting that the ingress is likely not coming from the extreme but from some other part of your system.
and of course, YMMV
 
The equivalent of tin foil hat materials do exist and they do work so you can experiment shielding WIFI waves. My experiments tell me that the processing of the WIFI data etc is more likely the root cause. Adding an external access point helps quieting my router but once I switch off the routers WIFI the sound improves further. (the external AP is located less than a meter away from the router)

Texture of instrumental timber for one.
Dynamic range (I know that digital has a higher range, on paper - that’s not how it sounds).
Naturalness of tone.

As I’ve stated before, the “wall” with digital is on the recording side. Thanks to Taiko, the D to A side has largely been solved.

I’m not talking about the Extreme at all in this post. Just an observation that shielding my Wifi AP reduced background noise.
Secondly, I also have a Switch + Network Card and only locally playback files... and agree the Switch/Network card made a huge difference!

Not at all, a wall wart is provided for functionality. We strongly recommend using a LPS. 1 LPS powering switch and router, when using a DAC cable as the interconnect, “sounds” better then 2, even more so when using the DC distributor.

Well.
Right now the dirty Swisscom internet box is my only router.
Up to now I have the firm believe that a decent lps for the router does help.
Will a second (clean Taiko) router obviate this need?

I do not know. When wifi access points on the dirty side and their power supplies can disturb the sound, I do suppose the dirty (or single) router power supply will be relevant, too.

Will a simple lps now be enough here with the Swisscom internet box?

simple inakustik reference LAN cable - Swisscom internet box (with Ferrum Hypsos or a simple lps ) - Ww platinum 8 LAN cable - Ediscreation extreme switch (lps included, running more LAN cables to tv box and other internet stuff) - Sablon LAN cable - Taiko switch (with wall wart, to be replaced) - Taiko DAC cable - Taiko Extreme - Sablon usb cable - T+A SD 3100 hv

I don’t know. I should give it a try. Right now I rather listen to music:)
Same with Ediscreation switch. Maybe better without.

Those who know are very welcome to comment.
