  1. Upsampling can be very good in some cases but there's always the tradeoff of more CPU load and not playing bit perfect. It also depends on the DAC you're using if upsampling is better or not. In particular, upsampling to DSD requires a completely different system tuning. It is definitely worth exploring both options: non-upsampling vs. upsampling. Via remote support I can always help fine-tune the system for one of the two.
  2. Thank you Armsan, please enjoy and you have a very good reason to stay inside these days.
  3. The Pink Faun I2S bridge is compatible with the W4S DAC PCM only up to 32/192
  4. Here're a couple of good pictures of a motherboard clock modification. The motherboard is a Gigabyte Aorus Master with an Intel i7. As you can see two clocks are replaced (Chipset and BCK). On this board we have to use a 24MHz clock and a 25MHz clock. This is different to most AMD based motherboards (AMD is commonly 25MHz and 25MHz). Both clocks are mounted on a board with linear regulation and HF pi-filtering. Both clockboards are mounted again on a PCIe dummy card. The PCIe card is used to place the clocks close to the motherboard. The PCIe has no other function. As you can see the PCIe card has a 2.5mm barrel (center positive) to power the clocks, also here is added extra HF pi-filtering. The required voltage is 5v max 2A. The OCXO clocks used in the pictures are Connor Winfield OCXO, the same modification can also be done with our own Pink Faun ULTRA OCXO clocks. These pictures give an idea of how we can modify motherboards used for DIY. Not every motherboard has the same clock(s) or has the clocks at the same position. For more details or options of your own motherboard please contact me directly.
  5. If your device was associated with a previous Roon Core (this can be the cse after updating ROON or the kernel) you may need to go to My Music -> Switch Library on the Squeezebox device itself to associate it with a new Core.
  6. Hello, I do not have experience with recent small formfactor mother boards. Maybe someone else have better recommendation. As for the PSU, the Pink Faun SPDIF bridge + OCXO clock can powered through the 2,5mm barrel with a 5v/2A supply.
  7. Hello, good question. As with everything it’s about implementation. When you implement the Pink Faun SPDIF Bridge in the right way it will be an improvement over the Allo DigiOne. The SPDIF Bridge is a PCIe card, so at least the motherboard you’re using must have one free PCIe slot. Also linear PSU for both motherboard and SPDIF Bridge is important. When you want to upgrade in a few steps, start with a linear PSU on the SPDIF Bridge with OCXO.
  8. First part of the Mono&Stereo review of the Pink Faun streamer 2.16x is now online. https://www.monoandstereo.com/2019/11/pink-faun-streamer-216x-review-part-one.html#more
  9. Hello Matt, small correction to my previous post, we're not at the X-fi as exhibitor, but you can have a listen to streamer 2.16 in the room of Very Fine Solutions. The Pink Faun streamer 2.16 is connected to the MSB Discrete DAC with DUAL power supply. Enjoy!
  10. 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.
  11. 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.
  12. 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
  13. Thank you, it was a pleasure meeting you.
  14. 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!
