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

I have similar problem with Symphonies Plus.
I like the sound quality, it is amazing for the price.
Recently, my system produces a humming noise, and this is coming from the Symphonies plus. The reason I can say this is that my cd player (CJ DF-1) has a pair of direct output with a high quality vol. control, and I connected CJ direcly to my Rogue power amp.
They are fine without any noise.

I replaced all 4 tubes of Symphonies plus including the 6x4 rectifier tube, but the same noise is still there.
I am not sure it is due to the DC current leaking or other issues.

I emailed YS to fix this issue and we will see how it goes.

If any others have similar experience, please share here.
