  1. Hi JL, thanks for doing this. I followed your lead and got 0.1% 50 and 75 ohm Vishays. The 50 ohm didn't work for me too - the driver could not connect to the DAC with it in place. The 75 ohm works. The sound did change - warmer, more analog but I sense a slight loss of airiness/breathiness. Still good and will be listening further.
  2. Hi Todd, Did you verify that the card is getting the 12V at the LP4 and if your PCI connection is OK? Early on in setup, I could bring up the card in Control Panel / Audio Devices and click on Test, and I heard the Windows test tones through the speakers. Separately, I changed the power to the card to feed it 12V directly from the LPS, and moved the DC-ATX away from the card as Jesus suggested and the sound improved. Jord mentioned too that 12V direct would be very good for the sound.
  3. Has anyone found a way to get the server to boot faster without the lengthy POST and beeping? I've think I've gone through the BIOS settings a couple of times but nothing stands out. Quiet boot looks to refer to just the POST messages and the motherboard still beeps. I'd like a Fast Boot option but I don't see it. Thanks.
  4. Hi Todd, Sounds good - I'll be making this change and powering the card with 12V from the HDPlex as well. I don't know if the board ties the 2 grounds together though - a question for Jord. I don't know of any other source for the 2.1mm to LP4 adapters - very useful for the stuff we're trying to do but I imagine it's a small market for DIY audiophile types. The PF board doesn't have a DC jack, only the LP4 connector in the rear of the card.
  5. Hi Jesus, Great suggestions, thank you! I'll do these.
  6. Getting it running with the ASIO4ALL driver was quite easy. I believe you still need to follow the PF card setup and configuration in Windows as documented in their manual at Windows I2S-bridge ASIO4ALL is available at ASIO4ALL - Universal ASIO Driver When you install it, you'll need to select the Offline Settings option (it's not selected by default). After installation, JRiver picks it up and ASIO4ALL v2 is a choice that you can switch to. You'll then need to run this Offline Settings program - it presents a few devices (3 in my case). It was then a matter of choosing each one in turn (they were all named High Definition Audio Device), running JRiver, and seeing if you got sound.
  7. Hi Todd, Here's the LP4 pinout:
  8. I think you should check with Pink Faun regarding the voltage requirements. The LP4 connector I'm using has both 5V and 12V and they are supplied on different pins.
  9. Hi Jesus, I'm using the 19V for the computer - the HD-Plex DC-ATX takes 16-24VDC. The HD-Plex also has a 5V output which I'm using for the SSDs. This made a nice difference though I think it'll likely be even better with a JCAT/Bakoon battery. OT - holy cow - I see that HD-Plex has a new product listed on their website - a 300W ATX Linear PSU with no DC ATX needed.
  10. Hi Kilroy, Just plain WASAPI. I plan to try the ASIO4ALL since EuroDriver says they have that working with the card, and Jord at Pink Faun says he likes the results with HQ Player too.
  11. I completed both USB and I2S server builds. The USB server is a CAPS Pipeline with these changes: PPA OS SSD with OCXO clock with JCAT BPS powering this PPA Sarah SATA cable for the OS SSD PPA Music SSD with TCXO clock PPA V3 USB card with OCXO clock E3-1240L V3 25W TDP CPU 2 AQ Jitterbugs plugged in but not in the USB data stream (didn't like it inline) Light Harmonic 10G USB cable -> Regen with Netron Star Clock, LPS powering this -> Supra USB cable Server 2012 R2 with AO 1.40, HQ Player PS Audio DirectStream DAC The I2S server is a CAPS Zuma with these changes: HD-Plex LPS with 250W DC-ATX 5V feed from the LPS just for the OS and Music SSDs (made a surprising difference vs powering it with peripheral power from the ATX) Pink Faun I2S bridge Server 2012 R2 with AO 1.40, JRiver 21 PF supplied HDMI cable to DirectStream Before finishing the I2S server (before the Pink Faun board arrived), I plugged in the SOtM USB card on the Zuma, ran it through the modified Regen and compared it to the Pipeline server. There was no contest - the Pipeline was clearly better - soundstanding, imaging, details... Partly due to this, I was expecting the Pink Faun board to not sound as good as well, but I was surprised - it sounds really good. Given the parts and price difference, I now wonder what a souped up PF-based I2S server would sound like. I give the edge to the USB server at this time but I plan to do more tweaking with drivers and software on the PF/Zuma machine. I can relate to what EuroDriver is doing now with his project and when he says "we know we have to run hard and throw a lot high quality parts at the USB implementation to keep ahead of I2S".

  12. Hi JL and HenSch, Thanks! Thanks HenSch for the insulation suggestion. I used the hardware that NewClassD provided without thinking about it. I have replaced the metal standoffs with nylon ones and added a piece of plastic against the back plate to make sure there's no contact with the chassis. I'm using an HD-Plex LPS. I built a modified CAPS Pipeline and the HD-Plex conveniently has 4 outputs. It has a 12V which I use for the clock and an adjustable 5-9V which I set to 7.5V for the Regen. Everything's sounding really nice with more running in.
  13. I did a clock mod over the weekend. The highs started out hashy but they've smoothened out and are silkier and nice now with some running time. I'll wait for a bit and see if the pot adjustment changes anything. For me, the changes weren't huge but nice nonetheless. I'm using a Paul Pang V3 USB card with an OCXO clock and thought it was very good to begin with. Thanks HenSch & JL for the inspiration!
  14. I'm going down this path as well. I'm building a CAPS Pipeline to replace my CAPS Zuma (with SOtM LPS + JCAT BPS). The CAPS Zuma will then be changed to use the Pink Faun I2S board. It'll likely be a few weeks before I have both done. Sound quality is my main goal too.
  15. Hi Elberoth, This is OT but I'd really appreciate your help. I think you mentioned that you built a Pipeline server with a Xeon E3-1240L V3 CPU. Is this correct? I put together a Pipeline server with this CPU hoping to get it up and running before switching the PSU to something better. and I'm getting a red LE6 LED in the top left corner. I replaced the PSU with a known good PSU and it still shows red. Can you please confirm that this CPU is compatible? Everything else is from Chris's list. Thank you.
