I visited the Warehouse as I wanted to assess the action and sounds of the new Casio PX-S7000 as I was keen to update from my PX-560M. The sounds were good but the action seemed to be similar which was disappointing. I was then shown the surprisingly more affordable Yamaha P515 which definitely had a better action, reasonable sounds and a louder speaker system. I was able to compare it to the Kawai MP11SE I also own which has arguably the best action of all digital stage pianos. I was then offered the opportunity to try a few of the smaller grand pianos to compare them to my U3 which ended up with me appreciating it even more. A few weeks later I made the decision to purchase the P515 and it was in my studio in Denmark in a few days because of the great service APW provide. I intend to use the P515 so my students can go busking and have also purchased a 16v Laptop Power Bank, which works great, to power it so as we can set it up anywhere in town.
