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

Hi all,

I too am considering this preamp. How is the construction of the preamp? is it kinda flimsy casing and so on? This is my first post in this forum. Well, if it's a simple mod of removing a cap, woopy. If it's not built real well, then that is to be considered.

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.
