I just recived a WA5 amp. I used a HD800 and ER4P (with adapter) on it. I can hear big floor noise at any volume expecially at high gain. I definitely can hear this floor noise at low gain too, but a lot quieter. I tried both stock tubes and my own premium tubes. No change. Can you please share your opinion on this issue? Thank you in advance!
