Not sure what the point of any of this is, his statement about the p515 didn't seem to warrant people here piling on him with supposed grievances from the past. Just my 2c.
Thanks sleutelbos, I appreciate your unbiased views.
Also I would like to reiterate why I'm here on this forum in the first place.
1. I plan on purchasing 1 or 2 digital pianos later this year for both myself and my younger daughters (4 and 8) to play on. This is why I personally am interested in key metrics (weightings, lengths, action friction, surface friction etc). I purchased professional piano key weights and built a key length measuring device using Arduino for this purpose. I also built a complete web search engine to search more than 80 online stores. If the technical information I contribute to this site doesn't interest you, then by all means please simply ignore my posts.
2. I have played piano for about 35 years and I have come to the conclusion that for me playing the piano provides the best form of stress reduction in existence. It is the only activity that can completely transport my mind away from the world and into a new one. I also studied undergraduate and graduate level psychology where I learnt that chronic stress (any stress lasting more than 1 day) causes the inhibition of Telomerase release in the brain. Telomerase repairs the ends of all of your chromosomes - and without it you are at much greater risk of ageing, cancer, heart disease, stroke, diabetes, and lower white blood cell count (a compromised immune system) amongst other serious conditions.
I hope this explains why I am passionate about pianos, and why I believe it is the best human invention in the past 300 years. Please keep these points in mind whenever you are reading one of my posts as I believe this will avoid any more shooting from the hip.
P.S. I also used to think that playing the piano has a calm soothing affect on people's personalities... I guess this forum crushed that dream
