I got a chance to try both the YPG-535 vs PSR-E453 at my local Guitar Center and I felt that the main piano sound ( and MOST sounds actually) were far superior on the YPG-535. I was looking to buy the PSR-E453 but now I'm not so sure. I have the following questions for those with experience with some of these keyboards.\n\n1. Should the YPG-235 sound as good as the YPG-535? I do not want an 88-key beast :) I travel with my keyboard sometimes. I'd prefer a 61-key, but I'm trying to make peace with the fact that I might have to buy a 74-key to get the best sound possible in my price range.\n\n2. Why oh why does the YPG-535 sound so much better than the PSR-453?\n\n3. It looks like the PSR-EW300, then the PSR-EW-400 (and soon PSR-EW410) are a direct replacement for the YPG line. Do they sound as good or better as the YPG-535? Because if they are just 76-key versions of the PSR-E series with the same sounds then I suspect that I'd prefer a YPG-235.\n\nThanks for your time.
