    Kali Audio IN-8v2 (Second Wave) 3-Way Studio Monitor Review

    You realise their speakers are manufactured in China?

    Minidsp SHD Review Updated (DSP, DAC & Streamer)

    I think you should be OK. As I said, it's specifically applying any DSP boost with the SHD itself that is the issue, as there is no digital headroom to accommodate these applied automatically.

    Minidsp SHD Review Updated (DSP, DAC & Streamer)

    The first post of this thread shows two jitter graphs. The first is from the original 2018 review (showing the minor issue) and the second is the one for the 2020 revision that this thread is about, showing that the jitter performance has improved. For info. there is a newer revision subsequent...

    Minidsp SHD Review Updated (DSP, DAC & Streamer)

    Just checked back... So the point of this thread was to show the improved performance of the revised version, demonstrating the issue you were referring to was 'fixed'?

    Minidsp SHD Review Updated (DSP, DAC & Streamer)

    Note that with any DSP applied including a boost (which Dirac Live does) it is a bad idea to run the SHD at 0 dB, unless attenuation has been applied somewhere else in the miniDSP settings to provide attenuation rather than via the master volume.

    Minidsp SHD Review Updated (DSP, DAC & Streamer)

    I wouldn't expect his to but this doesn't preclude him knowing more about what the issue was at the time of measurement.

    Minidsp SHD Review Updated (DSP, DAC & Streamer)

    Good point re. the inter-sample over issue being independent of output volume. I only mentioned it as it is the one known clipping issue that used to exist. Maybe @amirm could clarify what he was referring to in his 2020 review (maybe a measurement issue?), but I really don't think there are...

    Minidsp SHD Review Updated (DSP, DAC & Streamer)

    I'd guess Amir's comment related to inter-sample overs? There has now been an update that allows input attenuation to be applied to prevent this being a concern. Where DSP signal boosts the user should be mindful of allowing significant digital headroom to avoid clipping but there are no...

    Minidsp SHD Review Updated (DSP, DAC & Streamer)

    Note that one technical advantage of the SHD models is that they still using a 96 kHz internal sample rate in combination with Dirac Live, whilst a Flex with Dirac Live uses a 48 kHZ internal sample rate. I use my SHD as a streamer but have never used an alternative to compare. The Volumio...

    Bass output through the hole in the wall.

    Fair enough :) . Hope it works out well.

    Bass output through the hole in the wall.

    Whilst this is interesting from a project/theoretical perspective, I would personally block the hole up and use a conventional in-room subwoofer...

    4- channel DAC

    As you're buying new hardware, I would at least consider a miniDSP Flex, as a combined DSP and 4-channel DAC, or indeed the older/cheaper 2x4 HD.

    4- channel DAC

    Different thought: for prototyping, would one speaker be sufficient rather than two? You'd only need two DAC channels then.

    4- channel DAC

    You are assuming a USB connection whereas I was not. But I am guilty of not thinking broadly enough. I'm just used to using miniDSPs with multiple digital outputs where multiple stereo DACs are commonly used, in part as I'm aware 4-channel DACs aren't common.

    4- channel DAC

    I'd suggest otherwise. You don't want DACs with significantly variable latency but there are loads that should be fine. I use different DACs for my main speakers and sub for example. Edit: although digital outputs may be the issue here?
