Taiko Audio SGM Extreme : the Crème de la Crème

[matthias]

I’m afraid I don‘t understand your question. Anything defined as ‘bloat’ are essentially extra lines of code that are unused to achieve the goal but that occupy/utilise system resources either to the detriment of the final result or that require extra resources or work-arounds to offset their negative effect.

If it helps I use "bloat" as per definition of @romaz from post #3675.

Hi Matt,
That’s exactly the post I was replying to, so by definition, Extreme users wouldn’t use any features that one may feel is ‘bloating’ Roon

I dislike Roon and would be happy if there is a version of the Extreme with something like "Roon Lite" as per definition of @romaz or Audirvana.

Tried all the options and I had to agree that for the Tako exterme :
1. Sonore OM is better than Startech MC to convert the signal from switch to Optical that feeds Extreme ( both with Planet SFPs)
2. I have EtherRegen and was using it as it has SFO cage so I connected it direct feed via Planet SFP .
It works well , BUT I think it uses to much power and ER gets little hotter- everything colapses a little.
3. Ether Regen is EXCELLENT if you use it as w A-A side Switch only without use of SFP cage.
to convert the signal from EtherRegen (copper to fiber) use Sonore optical module.
4. The B side of the ER is great only if your system is lower quality ( DIY servers , totaldac server)
When it comes to Taiko extreme use A side only. It sounds a way better,

Last thing
5. Many here say that addition of the Jcat Telegartner M12 gold from MARCIN is a must and I am willing to give it a chance soon.
That might be the ultimate solution especially few will test chaining the TWO m12 to test if it boosts the SQ ,

I'm unclear as to the reasoning

AFAIK, no one with an Extreme uses the B-side of ER, all found the A-side superior.

Matt

I use DIY server and copper connection only, I found ER A to A is better then A to B in my system.

B side is kinda lack of dynamic which has a softer sound and the frequency extension is also smaller (nice mid).

Isn't the whole idea of all the tech in the eR to run it across the "Moat"? That is, A to B side, or B to A side. As I understand, and please correct me if I have this wrong (!),--- The reason the A side is better for the Extreme relates to it being gigabit speed, while the B side is 100 mbs.

So what about going into the eR on B side and out to the Extreme from A side (either only copper OR copper to OM to fiber?

Isn't the eR just an expensive FMC if you don't send the signal across the moat?

The B-side has only 10% of the speed of the A-side.
When you are using the A-side only the ER is not only a FMC but also a very HQ switch with five connectors.

Matt

I agree completely. I dislike software that is hugely complex, where I don’t need a great deal of its capability. I‘ve had 2 Roon free trials and both times ended up rejecting it for reasons of sound quality, where a much simpler system has been very easy to run and sounded a LOT better

So, and forgive my Neanderthal network knowledge, if one enters copper at the lower speed "B" side , across the ADIM "moat" and goes out either copper or fiber from the gigabit "A" side, aren't we getting the higher speed which the Extreme likes?

No, always when you cross the moat you will end with the reduced speed of 100Mbps, éither from A to B or from B to A.

You're both right, you're just talking about different "speeds."

1. A device X, connected to the 'B' side, is connected at a "link" speed of 100Mbps. This is the negotiated bit rate between X and the switch.
2. Devices Y and Z, connected to the 'A' side, are connected at a "link" speed of 1Gbps. This is the negotiated bit rate between Y and the switch, and Z and the switch.
3. When Y communicates with Z, they can potentially achieve an effective throughput (end to end transfer rate) of 1Gbps.
4. When X communicates with Y, they can only potentially achieve an effective throughput (end to end transfer rate) of 100Mbps.

Ok! this is interesting news to me. So if you're dac-connected device should optimally be fed gigabit data (like the Extreme), the eR doesn't really bring anything special in a switch. This must be why I never heard any improvement from the eR into the Extreme in my listening tests. I've since just been using it as a fiber optic fmc before the Extreme. I'm particularly interested to try the Sonore optical module in place of the eR.

(I do believe I heard an improvement to sq when I used the eR before a Mac mini).

Extreme owners: Do you find a benefit from using a linear power supply connected to the Extreme?

 

[tsaett]

The Extreme has already a linear power supply built in, it is not possible to connect another one to it.

 

[wil]

I use few ethernet cables.
I still own Jcat older cables that are very good.
I had them for last few years, but thinking of an ultimate upgrade
to Jcat Telegartner M12 switch that comes with Two 2m ethernet cables .
This is very expensive option but many say here that it adds something no other switch can do.

If I will be able to get it in this difficult times I will keep the ER and edgerouter and ADD the M12 as it is considered to give the best results when chained with other switches.

Kris, if you're only using the eR from the "A" side and so bypassing all the tech in the eR that only comes with sending the signal across the A to B moat, why add it inline with the M12? As I understand, this would just be adding another connection and another LPS at no benefit.

Steve . I am happy to notice we all got to the samme conclusion.
last week I tested extensively the Sonore OM . I use 2 of them both with Planet SFP.
one is used as an isolation point for my wifi access point
second sends the optical sream direct to the extreme.

They got not only much less warm with 5v DC insted of 7v or 9v
but also the saturation of the SFPs is much less and with that my Extreme sounds glorious .
I am amazed how good it is now.

Kris, Are you using the Single mode SFP from Planet Tech? Sonore sends multi mode SFP's and fiber with their OM's and can't tell me if they are compatible with single mode. Thanks

 

[wil]

Sonore OM are compatible with single mode-- finally got the OM's to work system.

I believe 100Mbps port always have a house sound that similar to low performance server, soft and quiet, lack of dynamic and extension compared to the 1000Mbps.

Just change the Lan card configuration in any server from 1000Mbps full duplex to 100Mbps would also yield similar result.

Same seems to be true of higher vs lower specs USB.

Emile, is active CPU cooling (air or liquid) frowned upon because of the vibrations created by spinning fans? I know the powering of the devices can be isolated using an external LPS.

Thanks.

Emile

In the first 157 pages, if you mentioned whether the liquid cooling in the Extreme is fan assisted or not, I could not find it.
Can you elaborate (again?) on the details of the cooling methods in the Extreme?

There are no fans in the Extreme.

The extreme has lots of fans.
