I have now a tyros 4 with the ms04 speaker system. I was considering buying a S950 for another room of my house. I was wondering how the built in speakers sound on the 950. On my T4 I have other equipment hooked up to it like a EQ and a sonic enhancer along with Yamaha HSa 8 monitors so it is not easily moved. I wanted another keyboard with onboard speakers to practice with in my family room. Can anyone tell me how it compares to the t4 and how the speaker system sounds. I have found in the past sometimes the onboard speakers sound really good in some keyboards. I use the piano sound with strings a lot... thanks for any insight you may offer. Ron
