Hi Keerth
Yes, we already have output capacitors on the output(10nF for LSD output), we also increase the capacitor to bigger, but make no sense.
For the power supply(VBB) of 3946, we have 2.2uF+220nF+100nF in parallel.
Have you some other suggestion of the HW circuit?

Hi Keerth
We find it will benefit the CE3 performance if remove the common mode choke on the output of HSD and LSD, and replace it with 0R resister in series with HSD output, one to five Ohms resister in series with LSD output, meantime enlarge the LSD output capacitor(original design 10nF).
Q: It will slower the rate of LSD(Thermal issue) if enlarge the capacitor with common mode choke, What about the resister design? (Larger capacitor have positive influence to the CE3). If the answer is YES, What's the limit of the LSD output capacitor?

Hi Keerth
Update the New design as below(Remove differential capacitor 1nF, HSD in series resister changed to 0Ω, LSD in series resister changed to 0.5 to 1Ω, a additional capacitor C3 added), What's the limit capacitor value of C2 and C3?
