  1. Now, although CXA81 is integrated I can not control the volume in the lumin app either have to purchase a DAC/preamp or DAC +preamp
  2. @wkliehi, I have noticed that during the upsampling from FLAC file (lumin u1 mini ) to DSD the sound diminishes and have to raise up the volume. Is that normal?
  3. @DuckTollerhope you are good because in Greece we are having a severe lockdown. Just wondering what matters more, upgrading my amp with a new or user one maximum 2500€ (with a DAC ?) or buying a DAC ( denafrips). I do not know in this amount of money if the difference on sound will be marked
  4. I think RME is out of the list because USB port is not for audio https://www.rme-audio.de/adi-2-dac.html
  5. Which one of Armature DAC's https://www.audiophonics.fr/en/dac-without-volume/armature-cronos-r2r-balanced-xlr-dac-24bit384khz-xmos-xu208-p-11831.html https://www.audiophonics.fr/en/dac-without-volume/armature-asterion-holo-spring-r2r-balanced-xlr-dac-24bit384khz-dsd512-p-12038.html Both products are discontinued. Do you consider it a disadvantage for future upgrade or something else? regards Nikolaos
  6. The reason discussing the DAC/preamp is that Lumin u1 incorporates LEEDH processing, https://www.luminmusic.com/support-leedh-processing.html, and that can be achieved via a pre-amp.
  7. Using AES/EBU digital port sounds better than USB port ? Tell me your opinion about denafrips ARES II. If I find a used armature I I think I will go for it. A second option is RME ADI-2-DAC-FS DA Converter. I think OCTO DAC8 is too expensive regarding using rpi.
  8. I will agree with you as soon as MQA does not provide bitperfect sound can not be regarded as a standard
  9. Hi, I was about to purchase Lindenmann bridge or network because its app is very intuitive but I was disappointed because no usb audio is available. My amp is designed to perform at its best sample rate PCM or DSD only with USB audio.
  10. Well, I would love to meet you. I think covid19 will be a step forward to deploy the telecom infrastructure and communication technologies. Yes, CXA81 https://www.cambridgeaudio.com/eur/en/products/hi-fi/cx-series-2/cxa81 uses the DAC you mentioned. Around 1,000€ is an affordable amount. What I do not know is how the CXA81 perform without its own DAC. I have never read anything about this because I suggest many users rely on its own dac. Connecting lumin via usb to DAC and then via DAC XLR analogue output to CXA81 XLR analogue in. You have not mentioned MQA what is your opinion.
  11. Great to discuss with you Duck, in the meantime thinking about DAC's I am posting a link regarding a breakthrough project worldwide first taking place at the observatory of Helmos mountain at Peloponnese perfecture in Greece. The next gen of telecommunications "fibre in the sky" the transfer of voice and data between earth stations and satelites via laser beams. https://www.ekathimerini.com/culture/256473/helmos-chosen-for-scylight/ You are invited to visit Greece and the Greek Islands and hope someday sitting on a beach listening to music directlty from audio system. reg
  12. @DuckTollerHi, we discussed months ago about the purchase of a streamer and a DAC for my audio system. Regarding the recently purchase of the lumin u1 mini the question if it is worthwhile to purchase a DAC/preamp or simple a DAC. If you ask me the comparisons between rpi4-volumio and lumin u1 mini I would say definitely YES with the latter the music opens wide more flourishing more lively. Thanks Nikos
  13. @[email protected]_mbpHi, When I connected Lumin u1 mini with cambridge audio cxa 81 amp via USB cable the screenshot 1 & 2 discovered on my app that means the DSD 256 disappears. Although you can playback DSD 128 and DSD 256-on the screen of Lumin app DSD 5,64 MHz and DSD 11,28 appears-you can not do downsampling on DSD 256. The cambridge audio CXA81 amp does not provide a screen to check what the DAC decodes from lumin but for a certain if its DAC was not capable it would not playback DSD 128 and DSD 256. Is it possible to fix the issue on lumin app providing DSD 256. Thanks
