Stax SRM-252S and iFi iPower2

09/06/25 14:37 Filed in: Audio

This article is a sort of community service announcement to clearly say that the iFi iPower2 works with the SRM-252S - at least for me. Something that was rather hard to find clearly spelled out elsewhere.

Why is this a data point anyone should care about?

After all it is just a 12V power supply and a device that accepts 12V.

It turns out that the SRM-252S does not work well with arbitrary power supplies and the iFi one is a lot more expensive than others (5 to 10 times the price). The cheaper linear alternatives are getting rare and the common switch modes sometimes work and sometimes don't and you can't tell from the spec sheet.

Sometimes satisfying an electrical load goes beyond meeting peak power demand and correct voltage and polarity. Read More...

Microsoft has been promising to update Microsoft Remote Desktop for MacOS for years. It is finally here and renamed Windows App. But changing the name of an application has security implications in OS X. If you can't save you updated connection information after the update then you need to make some changes in the keychain. Read More...

Replacing dlvr.it

12/03/25 15:59 Filed in: Systems Administation
After many years of using the free tier of dlvr.it (https://dlvrit.com) to glue together my blog and social media they made a decision to stop their free service. Let me make clear that this was a sensible decision on their part, if a lot of their users were low volume and never going to be upsold then this loss leading service was probably just a loss. So with no animosity I have moved on to an IFTTT (https://ifttt.com/) integration.
