shakeel,
I am no longer a Technics owner for several reasons. The support is a little harder to find, although it is there.
Styles are also a little harder to find, as compared to Yamaha.
The Hard Drive is proporietary and is quite expensive.
The mic input and vocal harmony is useless. I have not seen a 6500, the latest I saw is 6000.
You will like the operating system, styles and sounds on the Technics.
I can't tell you whether to cancel your order.
