Hi, I have a similar problem with Topping L30 as in this topic and I'm going insane from it.
To wrap it up shortly. I have Topping L30 and E30 and I have been using it without a problem since release (2012 SN). Recently I moved to new apartment and from first second trying out my gear I heard buzz in background, especially in KZ ZSN Pro no matter the gain. Since I own Flipper Zero I tried to run Frequency Analyzer and found out that I'm getting spikes at 800 MHz area that looks like is the main problem. If I completely disconnect L30 from anything but power I'm still getting the noise and in outlet where the noise is not peeking on Flipper0 Im not getting the noise.
Any solutions what should I try? Im open to getting new amp that will solve this issue (having really good deal on A90, but dont know if the same problem is gonna last)
