My impressions were:
1. A disappointing sound in comparison to my digital piano based on a Steinway and which I normally play wearing headphones.
2. I struggled to get much volume out of it but it was nice to really attack the instrument and have it respond.
3. The touch was certainly a little heavier but not so much that I struggled which is a testament to the designers of my Casio CDP100 which is only an entry level instrument.
4. Eventually, I did start to enjoy playing it and look forward to getting the opportunity to do so again soon.
