Hi folks:

For those of us who don��t have a Yamaha amp and speaker set included/factory installed with our Pro pianos, I��m looking for clever suggestions for pumping out some real sound out of either the DKC-850 controller (2 options for audio out on the back) or out of the silent piano/headset control box on the Pro.   It seems that the output in either choice is a very weak signal.  Even hooked up to a set of M-Audio AV40 powered monitor speakers, it just can��t keep up with the monster sound of the C5 grand (even with the lid down).  

I could put a pre-amp inline, but all the additional wires and possible line interference just starts to make the piano look more like it��s part of a recording studio/computer room instead of a beautiful acoustic instrument �� in my living room.  Plus I��m hesitant to attach any additional equipment to the piano because of possible heat gain and sympathetic vibrations (Yamaha��s recommended MSP3 powered speakers are too big to fit under even a 6��7 grand).   

Anyone come up with a cool sounding/looking solution?  

Thanks!

I am also looking for a speaker system to use with the DKC-850.  The Amp hiss from the build in piano  amp is too noticeable.

What I am looking at is a SOUND BAR  made for flat screen TV.  They are long and thin and can be mounted under the piano, and most include a wireless  SUBWOOFER...  

There are also YAMAHA  bars , that are all in one..  bit larger  and more money. 
Example of the  Yamaha is  YSP-4100 Digital Sound Projector with the dimensions of  40-7/16"W x 8-5/16"H x 3-9/16"D BUT costing $1700.   Lower cost ones are from Samsung, Sony, Polk  etc  

These sound bars include an amp, thus you only need to run the power and RCA sound cables to them.  Mounting will be key, with lots of felt to minimize vibrations. Wireless subwoofer can be place anywhere..

Like to hear others thoughts on these.

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...
