Re: [disklavier] Re: Amplifying a Disklavier Pro piano

I am MOST interested to hear so many people have had a problem with AMP hiss.   I too have had a problem since I installed the 850. 
With other unrelated equipment the problem seemed often to revolve around grounding.

When you install the 850 you place a new cable between the 850 and the old connection cable.  I have noticed if I jiggle the cable near the connection input on the 850  the hiss will go away.  But it comes back when I restart the equipment..

I wonder if the Yamaha engineers can look at this. It may be a simple grounding wire is needed between the 850 and the AMP.  

BUT I am no engineer. Just a few thoughts...
