  1. Some more information about Spread Spectrum Control (not my text) Spread spectrum controls are really added to motherboards for one purpose only - they are sometimes needed so that a device for sale within the US can include a legitimate Declaration of Conformity stating compliance with Part 15 of the Federal Communications Commission (FCC) Rules. This stipulates that operation of the device (motherboard), (a) may not cause harmful interference, and (b) must accept any interference received, including interference that may cause undesired operation. Sales of electronic devices within the US require the strict observation of all FCC rules and regulations. As a general requirement, every motherboard must be capable of generating and distributing more than one common clocking signal used to coordinate latching times as needed for the transfer and receipt of data across the many high-speed interfaces found in today's systems. Because it is uncommon for different busses to share similar operating frequencies, and because each must be kept independent of the others, a significant portion of motherboard resources are spent locating, monitoring, and regulating these circuits. Each circuit must include a reference frequency, or known base frequency, from which all other frequencies can be derived. A local oscillator usual provides this functionality. The problem is these oscillators can sometimes cause electromagnetic interference (EMI) centered about their operating frequencies. In an effort to prevent these types of undesired interferences the FCC, an independent licensing organization for devices capable of transmitting electromagnetic signals, either intended or otherwise, operating under the purview of the US government, enacted "Rule 15," effectively limiting the output power of such devices. Engineers, looking for a way to meet regulation, began using a method for limiting such interferences called spread spectrum clocking. Spread spectrum clocking causes the signal regulation circuit to slightly vary the frequency about the target frequency, effectively "spreading" the power over a somewhat larger frequency band. The method of operation can be used to control system output power below the FCC standard limits, allowing for a claim of full compliance.
  2. Please only go into BIOS and change setting only of you're exactly now what you're doing. The Pink Faun streamer 2.16 comes with BIOS already setup for good performance. It's okay to play around with different setting, but please be careful. Hello lpost, thanks for your insights in testing the spread spectrum option. Spread spectrum clocking causes the signal regulation circuit to slightly vary the frequency about the target frequency, effectively "spreading" the power over a somewhat larger frequency band. As you can imagine, even the smallest variation in a clocking signal can be enough to create data transfer errors. The fundamentals of the Pink Faun steamer 2.16 demand the cleanest, purest signal possible, which is why spread spectrum should always be disabled.
  3. Hello Matt, We went to the High-end in Munich earlier this year, and did the X-fi in 2018. Doing the shows costs so much of our time, we have to make a choice. We'll attent at the X-fi next year for sure. When you're living in the Benelux you're always welcome at Pink Faun HQ to have a listen to the streamer 2.16x and have a look in our workshop. Thanks for understanding, best Jord
  4. Thank you, it was a pleasure meeting you.
  5. The server runs ROON core, the renderer can do ROON bridge or HQPe. We have to decide when the full system is setup in the demo room. See you there!
  6. Kassandra II DAC and streamer 2.16x in DUAL configuration ready to rock Munich
  7. No, but the Pink Faun will be at Munich, I'm teaming up with the guys from Aries Cerat. The Digital source will consist of the Aries Cerat Kassandra II Sig D/A converter fed by the streamer 2.16x. We demonstrate in room D05 Halle 1. See you there!
  8. The Pink Faun card has an ASMedia controller and can optionally equipped with an OCXO clock. The card can be powered through the standard molex connector (5V only) or A 2,5 mm barrel allows you power the card from an external linear PSU.
  9. As you point out correctly all ethernet equipment has to include a certain level of galvanic isolation from the cable. But as you also point out there’re differences between the transformers used (the more expensive ones). Mostly used ethernet ports has integrated transformers in a very small space. With discrete ethernet transformer (like the LAN isolator) there’s less crosstalk and we can choosing modules with better common mode rejection figures than the integrated connector module.
  10. Here's a review of the Pink Faun streamer 2.16x and comparison with other music servers: https://www.hifi-advice.com/blog/review/digital-reviews/music-server-reviews/pink-faun-2-16x-1-3/
  11. Hi NiToNi, A lot of snakeoil, absolutely 😉 😁 Please take look at this interesting video about network tweaking. Of course you are free to contact me to test the LAN isolator yourself.
  12. Hi activist38, A new website is in the making for Pink Faun, so the link in your post is not active anymore. here's a photo and some more information about the LAN isolator: The Pink Faun LAN isolator provides galvanic isolation between the device that is connected to the network and the network itself. This without loss of speed. Even devices that play from an internal HDD and only use the network for operating and updating the firmware benefit from the LAN isolator. A network cable from the media player connected to an active modem/switch is a transmission hatch for high-frequency noise. With normal computer use such as e-mailing or surfing the internet, the high-frequency noise has no influence on the user experience. However, high-frequency noise that enters directly into the digital audio device through LAN is very undesirable. This influences purity in the high, which causes the space information to become blurred. The Pink Faun LAN isolator will ensure that the sound is less smudged, making details more audible, providing a better soundstage and a black background which in turn increases the dynamics in an audio system. The Pink Faun LAN isolator can be used on any audio device connected to a LAN network, even when the network is not used to stream music. Once the audio device has been assigned with an IP address and is active, the LAN isolator has a positive effect on the overall sound quality.
  13. For now we start with ROON only, the software is dedicated written for the Scion. The Scion has an auto update function and is configurable through the web interface. More options and new development can easily rolled out. If you don't want to go with ROON you can swap the SD card and use for example DietPi. Note that this DietPi and others are not officially supported by Pink Faun.
  14. Visiting the Lisbon Audio show 2019, Ultimate Audio is demonstrating the streamer 2.16x in DUAL configuration (ROON/HQPlayer) with a fantastic high end system. Sound is amazing, getting a lot of nice feedback. The 2.16x DUAL is not extremely good sounding, the numbers of the DUAL setup are extreme too: - 6 power transformers in total - the PSU of both machines have a combined buffer capacity of 1.6 million uF in total - 6 Ultra low noise Pink Faun OCXO clocks - Average processor load renderer (HQPlayer non over- or up-sampling) 0.02%
  15. Hi Matt, we're working hard to release the Scion asap. Some details of the Scion: - Roon endpoint - Flexible digital output for I2S / a list of compatible DAC's will be shown on the website when the Scion is available - SPDIF out - USB out (PCM & DSD) - Full Super capacitor power supply
