    Audio-GD DI-20

    Gustard C18 specs. Very similar to the LHY-OCK-1. I’ve been looking for a better clock to replace the Oscilloquartz OCXO (-90db/hz) in my PC setup. Would be a huge upgrade for that system. So price-wise the LHY audio clock looks to be a bargain if it lives up to its specs. Where is ASR when...

    Audio-GD DI-20

    The LHY-OCK-1 may be a decent 10M clock. -110dBm/hz at 1hz. 1 sq. wave and 2 sine wave outputs. Prices vary wildly but are offered at a little over $350us on AliExp. Some readable specs here… https://www.beatechnik.com/product-page/lhy-ock-1

    Audio-GD DI-20

    The DI-20HE is the best sounding DDC I have tried including the SU-6, SU-1, F1 of the Singxer varieties. I haven't tried them all but I even like sound of the Gustard U16 better than the Singxers.. I was judging sound quality with Audio GD DACs. YMMV depending on your system components. As...

    Audio-GD DI-20

    Yes... Thinking back to the last iteration of the R2R7 and it had a Blaster built-in and always connected to the Altera chip. Kingwa just has a blanket statement (under "Use Manual") to always power off when connecting any input or output. http://www.audio-gd.com/R2R/R7/R7EN_Use.htm

    @gimmeheadroom Just a safety measure. You are basically connecting GND of the PC to your DI/DAC and could cause a voltage spike until things settle. I blew up an Off Ramp 5 DDC hot plugging HDMI I2S to a Master 7. Blew the protection diodes on the OR5 HDMI interface. So better safe than...

    The HE-7 and R7-HE mk2 DACs sound more alike than different. Sort of makes sense as they share the same firmware, power supplies, and other electronics. The HE-7 is a touch warmer while the R7-HE has slightly more detail that is only noticeable on very low level passages. The HE-7 mk2 has the...

    Try the 32-bit version of Xilinx Impact programming SW. The 64-bit version will not run on my Win 10 x64 machine. Just type Impact in the Win 10 search box to find (14.6).

    Concerning the HE-1 mk2 preamp outputs. Each output is isolated… “3 outputs: XLR / RCA / ACSS (ACSS and XLR/RCA have the separate output circuit design so they can connect 3 units power amp simultaneously.”

    @Currawong Assume so… at least in the higher end differential DACs. The old product summaries used to state that single ended outputs employed all decoding stages. And have seen no product statements recently touting “straight thru” analog design. So assume Kingwa is using his patented ACSS...

    @Articnoise Thanks. I don’t see how my R8 MK2 comment above differs from Magnas. The designs share the same V2 DAC boards. And none of the power supplies are switchers. Cascading is another term for one large DC power regulator feeding smaller DC regulators for the circuits.

    Sorry for the confusion. Any new DAC with the V2 DAC boards.... R7, R8 , R27 with and without the HE supplies.

    Any DAC with the V2 DAC boards I would think. My R7 HE MK2 took every bit of 750-1000 hrs. to sound great. HE7 MK2 was just a few weeks.

    That USB programmer is for Altera which you already have. You need one specific for Xilinx.. Just search AliExpress and Ebay for “Xilinx USB Programmer”. We just went through Xilinx programming on this R7 thread just one month ago (March 20, 2022. page 563, link below). You may want to...

    @tonedeafmelomaniac Does anyone make a Bluetooth to DAC USB audio adapter? Seems that would be easiest.
