Ah, OK. Yeah. Tomato, tomato. 
I'm referring to the harmonics of the mains frequency not the mains frequency itself. In one of my recent power supply review videos you'll see those components extending well into the kHz range and creating all sorts of IMD products.

I got to the point where I concluded that the Micro Audio SMPS has higher switching noise than I'd like. Sami suggested that I try filtering, which I will.
The Connex SMPS300 uses an additional LC filter on the output. The Micro Audio doesn't have that ... yet.
What has also happened is that Mean Well released the LOP-600 series, which looks incredibly promising. If it works well, Micro Audio will be a tough sell. It is vastly more convenient to have a single supply rather than having to mess with two supplies in series, but would that be worth the 20-25% added cost compared to the LOP-600. Then again, the Mean Well RPS-400 and LOP-600 share the same underlying topology, and about 50% of builders had issues with the RPS-400-36, so maybe the LOP-600 isn't so hot after all.
Decisions, decisions.
As noted elsewhere, I have my hands full at the moment. I remain committed to finding a quality alternative to the Connex SMPS300, even though it'll be at a significantly higher price.
