  1. It’s oh so quiet, it’s oh so still… If you really want to treat yourself with a nice upgrade: get the Driade Flow Reference 808 interlinks (and the 405 speaker cables if you are in a good mood). Works extremely well with the PowerDAC. Music will never sound the same. No: I am not a dealer nor am I affiliated with this brand, I am just too excited not to share this with my fellow PD enthusiasts.
  2. Quick GoogleTranslate of John’s comprehensive answer (in bold the highlights for potential improvements): ——— Hi Vincent, I use good quality capacitors and chosen for a specific application. I use an LCR meter to measure and compare all parameters of capacitors. The capacitors were chosen based on measurements and listening tests. The value of the large capacitors on the side of the S/PDIF DAPI receiver must be 10000uF or higher, the purpose is mainly to filter out low frequency interference, hence the high value. The voltage must be 16V (even if it says max. 4.4V) because higher voltage gives a lower ESR. lower ESR = less distortion. The Fractal D/A converter board and S/PDIF DAPI receiver board contain very high-quality and very expensive Polymer Tantalum capacitors with -extremely- low ESR. These are located at the latch chips (sample timing) and at the MOSFET power switches. These are the very best electrolytic capacitors I could find for this application. Compact design is also important, a connection that is too long can destroy the low ESR of the decoupling capacitor. That's why I built everything so compact without wiring (piggyback boards and connectors soldered directly to the board). Electrolytic Capacitors in the PowerDAC-R: - Samwa RD or Nichicon FW(M), 10000uF/16V, comparable specs. ESR = 80 milli Ohms. Nichicon UKA is also suitable. Potential improvement could be achieved by using an even greater capacitance (15000uF or 22000uF). - Kemet / Vishay Polymer tantalum capacitors, 220uF/6.3V and 33uF/6.3V. ESR = 10 ... 20 milli Ohms. When tweaking, you quickly run the risk of adjusting the DAC to the distortion of a certain audio set (audible). If you connect this DAC to another set, the sound may be disappointing. So if you are going to tweak, you have to be 100% sure that the audio set offers a high degree of transparency and that the digital audio source delivers bit-perfect playback (a problem with Windows systems).
  3. I asked John for his suggestion for a proper caps upgrade and I will report back his answer.
  4. Hi, I don’t know what the goal is of this thread, but I must admit I don’t feel like attributing any longer since the energy has become more negative every post. For now: everybody that has a PowerDAC enjoy it to the fullest and everybody who hasn’t one yet: GET ONE ASAP! 😍 Happy listening Vincent
  5. How do you know which of the two systems produce the ‘most accurate amount of bass’ since we do not have a benchmark - at least I don’t - ?
  6. And what about the recently released Magician Aquarius? So many HQ DACS these days 🎉
  7. I think we can conclude as follows: - The PD plays way beyond its pricepoint. - PD sounds differently in all setups and the source/ power/ cabling does matter in some aspects (ergo we cannot say it is 100% source independent and that is no shame at all). - The sound character of the PD is slightly ‘dark’, ‘warm’ or ‘analog’ — I think we all mean the same. Is this a bad thing? Absolutely not, this is why many of us like the PD so much. - As always the hifi hobby is matching all components until your ‘favourite dish’ has been cooked. And everbody has a different taste, don’t we all? I rest my case. But I love to try some different dishes every now and then, also the French cuisine 😍. What a richness!
  8. One-to-one comparisons with Linn Klimax Katalyst, internal Hegel H590 DAC and Chord Qutest - and the PD did beat them imho. Further experience with the Mola Mola Tambaqui but not having compared with the PD (and I honestly think it will be very tough competition for the PD). I certainly don’t say that the PD is the best of all DACs, but I do believe it is hard to beat its price/quality ratio..
  9. People that are not familiar with ECd (large numbers - the whole world except us in the fora I would say 😉) and are curious (small numbers) will look for reviews and find none. Terminator DACs have been reviewed everywhere. But that’s the paradox with ECd: we want people to experience the DAC’s quality and try to convince them, but one the other hand, isn’t that the charm of being one of the happy few that can enjoy the ‘aurora borealis’ of sound (although the PD is not the one that beats ‘em all’)? Convincing can only be done by offering a one-on-one demo preferable in their personal setup. And that’s what the PD can do easily given it’s portability and the rbpi (for instance) as source. My neighbor is thinking to replace his newly purchased Linn Klimax DS (costing a lot) for this odd looking DIY device named the PowerDAC... In the meantime I think we have to acquiesce and simply enjoy. Happy listening today!
  10. You mean the Denafrips I suppose? Thanks for sharing!
  11. Will be Rpi incl. HifiBerry HAT (digi2 pro edition), Lindemann Limetree Bridge 2
  12. As always, the complete setup/chain is responsible for your end result. I.e. my Hegel H590 is fast as water and my speakers are of that kind that can keep up with this pace. Also they happen to be quite bass heavy (typical paper cones that are used) and tango really great with the characteristics of the PD.
  13. Only if it has been recorded in minimal 24/192 and played back via the PowerDAC!
  14. Thats what I am experiencing: my reference track for assessing fast/ defined bass is Rage Against The Machine - Killing In the Name (I presume you will use different tracks ;-D). PRaT is unparalleled imo. Anyways, let's give it a try in the coming listening session!
  15. I must say, having used the PowerDAC for over a week now, the lower registers seem to be more present and better outlined in comparison with the DA96. Your claim regarding electronic noise seem to fit with the "source immunity" claim made by ECdesigns. Can other people relate to this..?
