Taiko Audio – SGM Extreme Music Server
The Taiko Audio SGM Extreme is a State of the Art Music Server designed to deliver the most realistic sounding / live reproduction from stored music files and streaming music from Qobuz and Tidal.
The Taiko Audio SGM Extreme is a State-of-the-Art Music Server designed to deliver the most realistic sounding / live reproduction from stored music files and streaming music from Qobuz and Tidal. The hardware architecture is a dual multicore CPU’s running under a Taiko Audio custom assembled operating system built from the ground up using the Windows 10 components designed for industrial controller applications with SOTA process schedulers. All data and software storage is non-SSD and utilizes non-SATA, nonvolatile solid-state storage modules.
The Taiko Audio SGM Extreme is powered by a linear power supply with choke regulation and a large capacitor bank utilizing the highest audiophile-grade Dueland and Mundorf capacitors. Music files can be stored in the internal storage up to 24 TB or in a NAS (Network-attached Storage). The standard software suite is Roon with the delivery of the data stream to JPlay which delivers the data stream to the USB controller.

PUSHING THE BOUNDARIES OF AUDIO STREAMING
Emerging from many years of relentless researching, comparing, and listening, the SGM Extreme is the culmination of what is possible in the field of music servers.
It combines many technology breakthroughs completely unseen before in the world of digital High-End Audio. Only the best components from the most respected vendors are sourced for it, many of which are custom designed from the ground up.
During the lengthy design process, no stone has been left unturned, giving equal attention to resonance control, prevention of electric pollution, reliability, and user-friendliness. Due to its flexible and modular architecture, you can expect a very long life expectancy with both hard- and software updates, giving you the confidence of a future-proof investment in the best digital source for years to come.
Dual CPU design
In the past, you would always have to make a tradeoff when planning your digital source: Sound quality or user experience / ease of use. For us, there is no better software to browse your own music as well as finding new music through the countless streaming services than Roon. Since the start of the SGM project in 2015, Roon has therefore been at the center of what we are doing.
The choice to design a dual CPU system was for a large part fuelled by finding a way around the impact Roon’s luxury interface has on sound quality. It does enable Roon processing to become virtually inaudible, a world’s first in our experience.
With our groundbreaking custom allocation of processes, you can now have both: The best sound quality as well as the best user interface. What’s more, due to the low amount of heat that is generated due to this design, you can expect a much longer component life than a single CPU design.
In our research we found SSD storage to be a big bottleneck for the overall performance of a digital source. An SSD always connects to your system via the motherboard DMI chipset. For the Extreme we are using PCIe modules, which connect directly to the CPU and bypasses the DMI. Therefore we achieve speeds up to 4x faster than SSD which results in lower latency and much lower system noise overall, giving you black backgrounds, huge space rendition, and brings an ease to the musician’s performance, only matched by the very best vinyl and tape playback systems. We rely on the new VMD technology, that Intel introduced with their new Xeon Scalable line of processors. VMD allows us on the hardware level instead of the software level to have greater bandwidth on the PCIe interface, reducing the active processes once more.
You can select anything from 2TB to up to 24TB internal storage, eliminating the need for playback from external drives such as a NAS. Worried about backups? We found that RAID is not beneficial to the sound quality, therefore we strongly recommend to our customers to use an external backup drive that can be accessed remotely via the Extreme. Should you still wish to use RAID, the Extreme will handle this as well.
SELECTED HIGH-SPEED RAM
Ever heard of DRAM refresh? You should, because it is one of the main reasons why many think fewer and lower speed DIMMs are better for sound quality. In our research we discovered the true source of why RAM has such a big impact on sonics and was able to deal with it our way:
Our custom RAM modules have factory pre-selected A-grade memory modules, all dimm components (memory chips, capacitors, resistors etc) are matched to within a 1% tolerance and selected for low current draw. The side effect of this is refresh rate burst current is reduced by almost 50% and operating temperatures are much lower allowing lower refresh rates. Combined with power supply filtering this allows us to use 12 memory DIMMs with a very high combined bandwidth at very low refresh noise levels.
Low queue depth and latency
The Extreme is built for bit-perfect output without upsampling the data stream to cater to the latest premium R2R and Sigma/Delta D to A converters. WIth bit-perfect streaming, system latency (=active processing time) becomes a significant part of the resulting sound quality. In our design of the Extreme, we focused on providing the lowest latency possible for every instruction or set of instructions the server has to manage.
Why? To maintain as short a queue depth as possible in all system components, which leads to a constant current draw, low EMI/RFI emissions, and powerline pollution. This is the reason the Extreme’s computational power seems to be overkill, but in fact, is paramount to the resulting quality of the audio stream.
This makes also sure, that the Extreme will not be harmful to any other associated equipment you have in your music playback chain.
The operating system has been custom stripped to the very core of what is absolutely needed to run music services. We believe our solution to be better and more reliable than any aftermarket software and even better than running the whole operating system in RAM.
MULTI-STAGE ULTRA LINEAR POWER SUPPLY
Our 400W linear power supply is a new inhouse development, specially created for the Extreme and its special needs. It is comprised of only the very best capacitors from Mundorf and Duelund, combined in a way we found to be most neutral to the sound. The chokes are supplied from Lundahl and were selected also by ear.
Extensive vibrational measures have been applied to make it as resilient as possible. Again Panzerholz was used in strategic places to shift the vibration patterns into a benign territory. The whole design is built for low temperature, long life, and above all best sound quality.
The Cooling System
During the design phase, we quickly came to the conclusion, that none of the available cooling systems would suffice our demands. Therefore we designed our very own custom 240W passive cooling system – no active parts, no fans, no noise. Many aspects need to be considered, none more important than component longevity.
We found that most aftermarket passive cooling systems degrade in efficiency over time, that is why we machined the CPU interface with a precision of 5 microns tolerance (0,005mm!). We also use solid copper for the heat sinks, for twice the efficiency as regularly used aluminum. We estimate that our custom solution will lead to a prolonged component life between 4 and 12 years extra, depending on the use and environmental conditions.
The Chassis design
As physically imposing as the chassis of the Extreme may seem, everything is there for a reason. The finely machined aircraft-grade aluminum available in silver or black acts as a shield from external noise, but also keeps your other components free from pollution. The heavy top for example hosts a total of 6.000 machined holes. These holes are “waveguides” which attenuate emissions by 81 dB which is around 10.000 times!
Inside you will find multiple measures to tackle the vibrational behavior of the component. Copper and Panzerholz have proven to be the best materials for this task, bringing low mechanical impedance and a benign vibrational spectrum to the table.
The footers too are custom designed to give optimal coupling to the surface below. The Extreme is a sight to behold and built to last.
