there is a lot of hum noise on both channels.
2 of 2 found this helpful I am using a Reisong A10. I bought a new oldchen EL-34B amp of the same type and compared them with each other.
The Oldchen EL-34B sounds more powerful, but disappointingly hum is audible on both channels. Maybe it's like AC harmonic noise?
This noise makes it unsuitable for listening to music on a quiet night.
I think the oldchen EL-34B's hum noise is $50 cheaper than the Reisong A10.
