  4. "the DirectStream’s output stage includes high-speed, high-current analog video amplifiers driving an output transformer; the DSJ uses similar passively filtered amplifiers that drive the output directly, with no transformer." https://www.soundstagehifi.com/index.php/equipment-reviews/1004-ps-audio-perfectwave-directstream-junior-digital-to-analog-converter And from the manual: "After processing by DirectStream all input data is converted to double rate DSD (5.6MHz) and output through a passively filtered analog section consisting primarily of a high-quality audio output transformer. Elimination of the classic active analog output stage, with all its difficulties running at these high frequencies, have been implemented with a high quality passive audio transformer." https://www.psaudio.com/wp-content/uploads/2015/08/DirectStream-DAC-Owners-Manual-V4-Rev-A.pdf

    The iPhone Xs and Xr release

    Ya, when I say years, I really mean years. Since I bought my iMac in 2011. Here is my Mac playing to my Sony cans right now: They've always said it's just a battery consumption thing with iOS portables.

    The iPhone Xs and Xr release

    Apple have been supporting aptX for years - on Macs. They've always said iOS doesn't support it due to increased battery consumption.
  7. Ha, that's probably a question for Mr. Kuei Yang Wang himself. I suspect he's been very happy for the DSD1793 for a very long time. With the new Pro iDSD: "The Pro iDSD uses a quad 'core' of iFi audio's bit-perfect DSD & DXD DAC by Burr-Brown in a custom 'interleaved' configuration. A total of eight pairs (four for each channel) of differential signals are used and mixed. While the Pro iDSD does include an FPGA for digital filter duties, the FPGAs themselves do not perform d/a conversion. There are always external d/a sections, with a limited number of elements. In the Pro iDSD we use four interleaved 64-element converters, to give a total of 256 element DAC per channel, manufactured to the highest level of precision. Discrete DACs added can neither offer those elements' numbers nor the accuracy required. All signals to the DACs are re-clocked with the low-jitter Global Master Timing® derived master clock from the AMR DP-777."
  8. Yep, using the BB DSD1793 - working very closely with BB Engineers years ago to do things others weren't able to do, or weren't doing (he says). His DAC output stages (more important than chip used?) have always been discrete though, with his flagship DACs anyway.
  9. He's been using the DSD1793 chip for many many years. Same used in the new Pro iDSD DAC.
  10. His latest DAC, Pro iDSD can up-sample to 45MHz. I bet he dreams of the day the Class D switching frequency can also be at 45MHz. I've been a fan of NCore and ICE amps too btw - but like everything, I'm sure there will be improvement over time.
  11. In a boom box just to start with maybe? He mentioned it was trickle down stuff from an abandoned AMR project. Interesting his talking about clocking too. Master clock is also at the same switching frequency, ~1.5MHz?
  12. Interesting chat here with AMR's/iFi Audio's Thorsten Loesch. While this is more a lifestyle speaker he talks about the switching frequency being around ~1.5MHz and other things he's done with the Class D amp/s inside to make things sound better to his ears.
