QA480 availability

Any idea when or if?

Hi @Rocky, I don’t think the QA480 will come back as we know it today. The reason is that there are some new DACs that are able to do better than discrete oscillators anymore. But the need for a notch is still very valid. There’s some work going on there (see references in the forum to measuring Hypex amps) but I have no idea of the timeline yet.
