    Motu M4, spurious tones at 44.1 kHz, excellent performance at 48 kHz

    This is an M4 recently bought off Amazon Warehousedeals. It has firmware 2.0 and the additional screws on the combi connectors, so I suspect it is v3 but haven't opened it up. Performance in loopback is better than what Amir measured (I suspect on v1), however, I get strange spurious tones...

    Qobuz US vs. European catalogue?

    Quant Asylum QA403 with ESS DAC and ADC

    https://forum.quantasylum.com/uploads/short-url/e9EUxkUod8AstX3q4DM5uLsmMNL.pdf That didn't take long for them to replace the QA402.

    inconsistent IMD measurements in Hypex data sheets and a look at Amir's measurements

    I was trying to establish the pecking order of nc400, nc500oem and ncxxxmp from the data sheets. THD+N are difficult because you get a mixed bag of HD, noise and EMI. I thought IMD might be a nice way to establish whether the amp has sufficient loop gain at near 20 kHz but it turns out the...

    AKM fab massive fire damage

    https://www.prosoundnetwork.com/business/akm-factory-fire-shakes-up-pro-audio-industry Luckily, we are talking about regular CMOS rather than BiCMOS or thin film with laser trimming, so hopefully they can switch to foundries. Still a major disaster for the numerous small companies offering...
