Popular Post StreamFidelity Posted July 20, 2019 Popular Post Share Posted July 20, 2019 @brother love Many Thanks. I found the mistake with me. Crucial again is the clock frequency, which must be at least 4GHz for the EC modulator ASDM7EC and DSD 256 for my system. Since I run a fanless PC, I come in the temperature in the critical area. At the moment everything is fine, the continuous operation is crucial. poly-sinc-ext2 + ASDM7EC + 44.1 / 24/2 -> DSD 256 Runs smoothly with a very good sound. The CPU utilization is 16%. The power consumption is 34W, which is not a problem for my HDPLEX 200W Linear Power Supply. poly-sinc-ext2 + ASDM7EC + 96/24/2 -> DSD 256 Sensational sound. Also runs smoothly. The CPU utilization is 21%. The power consumption is 39W. Conclusion For me the EC modulator ASDM7EC is only really good with DSD 256. With DSD 128 I found it too lean. asdf1000 and k6davis 2 Grigg Audio Solutions Owner StreamFidelitys Setup: Sonus Faber Amati Futura | T+A M10 | T+A SDV 3100 HV | fis Audio PC & Server | GigaWatt PC4-EVO+ | JCAT OPTIMO S ATX | FARAD Super10 & Super3 | Keces P8 | Afterdark Buffalo Switch | fis Audio Cables | Solidsteel HJ-3 / HY-A | Formfeld 1 | ABSORBER LIGHT | Link to comment

Can your i9-9900K do PCM192kHz to DSD256x48 with ASDM7EC modulator, with ext2 filter? And which fanless case and motherboard, if you don't mind me asking? Link to comment

Since I currently have no problems running DSD 512 (filter: poly-sinc-xtr-lp-2s, shaper: AMSDM7 512 + fs) with an Intel Core i5-8400T, I am not afraid without a GPU. Some will wonder why I chose a gaming board. These are just very robust and equipped with good components. Pink Faun does the same. 😉I believe that good hardware is essential for a good sound. Added to this are memory with very low latencies and superfast SSDs. For extremely important I consider a trouble-free data transport and a clean power supply. The JCAT USB and NET cards are equipped with Femto clocks and are powered externally by the HDPLEX 200W LPS with 5V each. The same LPS in combination with the HDPLEX DC-ATX converter is designed to provide the new audio PC with clean power that is free from high-frequency noise. The operating system comes Server 2019 on it, optimized with Audiophil Optimizer 3.0 (to come in late May) and Fidelizer. I'm really looking forward to my new project. 😀 k6davis and asdf1000 1 1 Grigg Audio Solutions Owner StreamFidelitys Setup: Sonus Faber Amati Futura | T+A M10 | T+A SDV 3100 HV | fis Audio PC & Server | GigaWatt PC4-EVO+ | JCAT OPTIMO S ATX | FARAD Super10 & Super3 | Keces P8 | Afterdark Buffalo Switch | fis Audio Cables | Solidsteel HJ-3 / HY-A | Formfeld 1 | ABSORBER LIGHT | Link to comment

Since the CPU is just quad-core, it is fully busy with the modulators and such. If it stutters occasionally, ASDM5EC is probably just about lighter enough that it may work fine. Thank you, you’re right: no stutters with ASDM5EC with these settings. Problem is that I prefer 7th order modulator! Still, it’s lovely for now. Link to comment

Lowering latency increases overhead and CPU load. On Linux I use 100 ms buffer (latency) and it has been generally best. It is also important to keep it high enough that it doesn't enter into audio range. 1 ms buffer switching period means 1 kHz noise. 100 ms buffer switching period means 10 Hz noise. USB Audio Class has 125 µs packet interval and that's where the 8 kHz ticking noise comes that you can see in output of some DACs. P.S. Technically it shouldn't be much problem to reach that 125 µs latency on Linux if you want to, I got that kind of figures already 10+ years ago on old VIA CPU. rando and asdf1000 1 1 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

But what you are saying is that we need to actually increase the buffer to at least 100ms??? My recommendation is 100ms. This keeps activity period outside of audio frequencies and doesn't have much overhead. For NAA backend, leave it at "Default" unless you have a good reason to do otherwise. With ASIO, leave the setting at "Default" in HQPlayer and adjust the buffer size from the ASIO driver control panel. At least something that would correspond to 100 ms, or otherwise as large as possible (taking into account the sampling rate you are going to use).
