I sound absolutely fantastic on any brand. Mainly cause it's me they came to hear, not the keyboard. I must sound fantastic, otherwise I wouldn't be booked two years in advance.

And lets be realistic, the weight of the keyboard's shell has absolutely nothing to do with overall sound quality or build quality. A carbon fiber case could hold the same contents as a steel case, weigh half as much and sound identical. And, the carbon fiber case would be twice as strong - so weight is meaningless.

Corvettes are made of fiberglass, very lightweight, and very expensive. But a Shelby Cobra is made from aluminum, weighs far less, but the performance far exceeds the vet. Then there was the Griffith, which was also made of fiberglass and housed a big block V8 - I rode in one and it was like being strapped to a rocket sled. Unbelievable, but that lightweight car only stayed around for about a decade before it was taken off the market. It was one of the most incredible performance cars on the road and track. http://en.wikipedia.org/wiki/TVR_Griffith

A lot of newer sailboats now have carbon fiber masts instead of aluminum or hardwood. They're far stronger, much, much lighter than either, and because of their incredible strength, no support cables are required to absorb the stress of the sails, thus clearly demonstrating weight has no bearing on quality or structural integrity here either.

Give it a break guys - everyone knows weight is meaningless when it comes to anything other than precious metals and gemstones.
