  1. Hi Chris, Hi Maier. Great to read that you both have had a wonderful time together, listening to music and enjoy live. All the best from my side. Juergen
  2. Hi Chris. Wow, this is a great project. Congrats! Juergen
  3. Hi Mitch. Great Report. Thanks. One question, as this seems to work “dynamically”: If you would make some steady state frequency response measurements with different levels, will you then be able to see changes / correction in the resulting frequency response? Juergen
  4. Hi Mitch. Happy New Year. Once again, I appreciate your thorough work. Yes, it takes a while to read all the "pages", but it's worth every paragraph. Thumbs up.
  5. Happy New Year Chris and a great idea with going into the audiophile style 😉
  6. This could have 4 different reasons: Microphone, Mic Pre-Amp, Tape Head or Venue Noise This could be the SMPS noise of the polarization voltage that could go into the signal for 2 reasons: Either the signal transformer / path is not fully balanced, so that the SMPS noise is not canceled out, that would otherwise be the case with balanced signal path (if the in-phase path has for example 1k1 and the off-phase path 1k0 input resistance), or what I have had with older Neumann Tube of FET mics is, that the filtering electrolyte got a cold solder point. It is always good to
  7. Hi Mitch, Hi Archie. Very nice. I would have liked to join you for this event. It would have been fun, for sure. Thanks. Juergen
  8. For my Genelecs 8260 in my Mixing / Mastering Room, that are coaxial from low mid on, so very good sound stage and localization for near / mid field mixing and mastering, but not time coherent, I have the miniDSP Dirac DDRC-22D (Digital-In to Digital-Out) and use this for Room EQ (that could the Genelec GLM also) and also to make them time coherent, and use the digital volume control of the miniDSP to control the SPL. Yes, I know, the miniDSP does run internally with 96 kHz sample rate, and does SRC all other sample rates, but being time coherent up the 48 kHz (96 kHz / 2) is of much higher of
  9. Hi Mitch. Wow, another great review from you. Congrats on that. I enjoyed every paragraph you have written. I am familiar with both speakers (Dutch & Dutch 8c and Kii THREE) and do agree with many points you have described. But for most, it is great to see such thorough review of speakers with the focus, how they behave at home, and not mainly in anechoic chambers. Juergen
  10. Hi Mitch. What a great work and write-up. My full respect for this level of clean analysis and writing. This is extraordinary. Thanks. Juergen
  11. Congratulations Chris, also from my side. Great. My best wishes for you for the upcoming future.
  12. Hi Pal Good, that you join this group. My two points, are not adressed against you in any way but: MQA is lossy, where plain PCM would not, and concerning the sound quality of actual releases. If I would remove every actual release, that do have inter sample overload or native overloads (leaving aside the much to heavy dynamic compression), then nearly no pop / rock release would remain. Juergen
  13. New Masters? And if every recording has to be re-mastered individually, to get the MQA approved sound, why not just remaster into "regular" PCM files, just with less dynamic compression and less inter sample overloads and have still fully compatible pure High Res PCM files, that can be used with digital room corrections or with slide volume control (speaking volume matching) and still have regular 96k or 192k rate, that work in High Res on every regular High End DAC? Juergen
  14. Hi Chris This question can be answered due to the 24 Bit transparency of AIFF, ALAC, WAV and FLAC. You can convert (or should I say, you should be able to) the MQA FLAC file one hundred times between AIFF, ALAC, WAV and FLAC to any version, and when playing back, the MQA led should / must “shine”. More interesting would be, will there be a software decoder, that could convert the MQA “packed” file, into a “pure” 352 or 176 kHz PCM file, or speaking, unfold the MQA origami for non MQA DACs or for DAWs.
