Last month a music retailer posted a video featuring the 4stage pianos on the market. The Yamaha Cp4, Kurzweil Forte, Nord Stage and Roland RD-800. Missing from the comparison in our opinion was the Privia PX-5S. So to even the playing field, we played and recorded the same riffs using sounds from the PX-5S. The other 4 instruments are 2-4x more expensive. Listen for yourself to see how the PX-5S stands up against the competition.
