  1. I am an enthusiastic oversampler and want to understand the process better. If I upsample 44.1kHz to 88.2kHz, will the Nyquist frequency be raised from 22.05kHz to 44.1kHz? The anti-aliasing low-pass filter can then be less steep? And the original analog waveform can be reconstructed better? Or are there other reasons for oversampling?
  2. Thank you. Yes, the acrylic glass with a thickness of 10mm breaks the light very nicely.
  3. Many Thanks. I'll just try it out now. 👍
  4. I don't understand how it works. Audiophonics writes: The AXF-107 module from Elfidelity is a switch mode power supply filter for computers connected in PCI Express or PCI Express 16x and designed to provide cleaner power to all connected cards (sound card, interfaces, GPU ...). My questions: 1. Is the PCIe card simply plugged into a free slot and "sucks" EMI interference? 2. How is the power consumption? 3. Are there any recommendations as to which slot to use?
  5. It depends on the purpose. As some have already written, it is highly recommended for upsampling with the HQPlayer. Hyperthreading does not increase the computing power as some think. Instead, the parallel processing is distributed over more (virtual) cores. The manufacturer also recommends hyperthreading for the Solarflare SFN8522 NIC to reduce latencies.
  6. Complete agreement! I only know of one DAC that has this: Lumin X1. I hope it doesn't get too off topic. The sound engineer I spoke of also makes cables. To put this into perspective: I don't sell these cables. The LAN cable can separate (off) or connect (on) the shielding at both ends of the cable using small dip switches. This enables 4 operating modes. We separated the shield at the output (connection to the DAC). The shielding was on at the entrance (from the 10GTek media converter). That sounded best to us. At the output came the LAN isolator. This immediately i
  7. Jussi, the last few posts were a revelation of your way of thinking. I thank you for this. Much of what you have written is absolutely evident. I disagree with some things, but I think the open discourse will help everyone. 👍 This is one of the things that I thought fiber opted to do. I recently had a sound engineer with me and we tried out LAN isolators. In several places I have to leave the optical path, for example with the DAC with NAA (T + A SDV 3100 HV) which only has a copper LAN connection. The network isolator emosafe EN-66e actually brought an increa
  8. Many Thanks. This thesis is known to me and the noise exists. This can be restricted with measures: and switch off network card adapters that are not used, use high-quality NICs such as those from Solarflare, etc. I have very good experiences with this.
  9. I guess I know what you're getting at. 😉 There have been many reports that network traffic is interfering with audio output. I think so too, but I have solved it differently (among other things by different core assignment for Ethernet). In connection with our test, however, this don't matter, as both streamed and hard drive came from the NAS (HFX RipNAS Solid). This two PC solution is wanted because the data octopus Roon must be isolated from the audio PC endpoint. A picture should clarify the Ethernet route.
  10. Yesterday I did a sound check with a sound engineer and we compared Qobuz vs. NAS. For the sound engineer, the difference was even 15% -20% better with NAS! I didn't hear the difference as well as the sound engineer, but NAS sounded better to me too.
  11. One of the most important settings is to avoid busy cores. Look in the manual: The same applies to LatencyMon. I always only take the last two cores. 😉
  12. Because they don't see audio applications as their main purpose? I think so. It corresponds to the philosophy of Steve Jobs that hardware and software cannot be separated from each other. Yes, but all software is tested by Apple before it is approved for MacOS. It should happen that not all processes simply sleep, but wake up at an inconvenient time. If the processes are not there, that cannot happen. 😉
  13. For music or something else? What criteria do you use to rate this? I was just taking a screenshot of my McBook Air (Intel i5 Core), where Google Chrome is annoying me again with a high load. I only have this page open. Almost 400 processes (twice as many as Windows unoptimized) and almost 1,500 threads, the majority of which are definitely doing something other than playing music. I only use my Air for the remote control of Roon / HQPlayer.
