Do Audio Experience Symphonies leak DC current?

I'm thinking about trying an Audio Experience Symphonies preamp, but i read a post where someone said their symphonies pre leaked dc current, putting their classe ca-100 into protection mode.

here:

i have a ca-200, which also does not like preamps that leak dc current (per manual).
has anyone else had this happen with this preamp, or was this case an isolated incident caused by a faulty component in the preamp?
thanks

Hello! Jkimsland.

The humming noise is NOT from DC current leaking.

The cause of the hum noise is 47uf/450v caps at power supply to lost.

you replace the 4 pcs 47uf/ 450V caps at power supply to new item ,that can fix this problem.

If, you need the new 4 pcs 47uf/450v caps.
You can e-mail your address to me.
I will send the caps to you.

Thank you.
