I ended up switching back to the 5pF capacitor. With 470pF, the nearby STN9360 starts behaving incorrectly, so something in my implementation clearly doesn't like that value. I replaced the output capacitors on the switching supply with four 0.1µF/50V MLCCs, just as Kevin suggested. After doing that, the ripple on O+ and O− at around 120kHz dropped to roughly 96kHz. At this point it seems like the tiny residual hiss may actually be related to the switching supply rather than the amplifier itself. What I'm not sure about is whether a 120kHz switching component could somehow be demodulated or otherwise make its way into the audible band.

Just finished watching. Entertaining.

I'm looking forward to those as I'm slowly working on my own version just for me, i.e. fixing how they sound. :) I got these recently: https://poloyoaudio.store/products/hongshu-eh1 It is my third one of these as they design has been maturing over the years. I'm waiting on a replacement set as mine had some noise issues in one driver so I'll do a proper write up as they arrive but I do like them a lot. The earpads are crap but there is a lot of potential there.

Agreed on all accounts.

Been a while since I built it, but I had the 470pF from the start and didn't notice any drift/rise in output voltage. Can have a look this weekend, was going to open it up and swap to a new trafo anyway.

Thanks for the timing reminder. No biggie if you miss Bust. Fraenkel Gallery isn’t far.

You'd better hurry, as Sunday is the last day, and this weekend is the Marathon which will make things interesting. I'll have to see if we can fit in a visit to see Boom and Bust before it's last day on August 2nd!

Here’s one of my secrets - I’ll take Coltrane and Bill Evans over Miles Davis any day. That’s probably little to do with the artists, but damn is this album great (the cover art is not)

Can’t wait. Did you also see the Boom and Bust photo exhibit? If so, how was it?

Sometimes you just want to watch a man repair a kitchen knife - there are a lot of fake restoration and repair videos online, but this one is like relaxing ASMR - never abuse a fine knife like this:

Unholy carp!

yep exactly. on the back of the board as close to the output pins as possible.

Just to confirm, do you mean adding a .1 to 1 uF ceramic capacitor directly across the RKZE-1515 isolated supply output (+15V to -15V) that powers the CCS section?
