I have played the CUP2 many times since it came out and was initially impressed by its beautiful contemporary cabinet and big acoustic type piano sound through its powerful 140 watts of bi-amped internal stereo sound system. Here are the specs of this piano below. Click on picture for bigger view of the piano.

Unfortunately when it comes to pedaling using the damper pedal, the CUP2 right damper pedal is not capable of allowing for more advanced pedaling technique which includes having the pedal recognizing the "half-pedaling" function found on all other major digital piano brands such as Yamaha, Roland, and Kawai. When playing a regular acoustic piano, you are able to press the right damper sustain pedal and get a variable amount of sustain (depending on how far you press the pedal down and then let it up) which is known in the digital piano world as half-pedaling or continuous detection pedaling. Kurzweil does not have either one and instead uses a keyboard style on-off sustain function which is very basic and not something that I enjoy using. Even though the right pedal looks like a piano pedal, it does not really operate like one and that's a big disappointment as well, and this function should be standard on any digital piano in this higher price range. To further add to my frustration with this model, the piano pedal sustain time (aka: decay time), is quite short in the middle to upper octaves...not at all like a real piano in that way. In this price range you would expect that when you press a key and a piano note is heard, while you have the damper pedal pressed down, you would expect the sustain.decay time of the piano sound to be reasonably long. However, it is not. The piano sustain/decay time is short and fades out quickly so that the notes don't continue to resonate through the piano. This is a big deal for me when I try to play beautiful legato music using damper pedal and expecting normal length sustain time, but it's just not there for the acoustic piano sound. Very disappointing. This is possibly due in part to the low polyphony processing power among other things. In any event, I don't like it at all. Even the new $600 Yamaha portable digital piano is better than that.
Another big drawback to this model in my opinion is the key action. The key action realism is the #1 thing that shoppers should be concerned about when looking for a good digital piano in this or any price range. Although the CUP2 uses a key action movement with graded hammer style semi-wooden keys made by the Fatar key action company in Italy (Fatar is known to have some better key actions), the action is quite stiff to push down on both white and black keys (black keys are really stiff to push) and the action is also sluggish in my opinion, especially when playing softer, gentler piano music. The keys don't play consistently (evenly) in movement across the 88 keys when pressing gently on the keys. This key action situation is referred to as heavy touch weight.

So what do I like about this piano? I like the cabinet & volume, and to some extent, how the controls are mounted in a little pull out drawer under the left side of the piano so that it can be tucked away and not seen which makes the piano minimalistic in its looks. But that little drawer control panel can also be a bit frustrating to use because the controls and buttons are not in front of you above the keys for quick selection. You have to pull out the drawer every time you want to use something new and/or have to continually look down to your left side to use the buttons on top of that little pull-out box. Personally, I prefer all controls, buttons, display screen, etc above the keys within easy reach and access. But the biggest thing that I absolutely do like are all the NON-acoustic piano sounds including electric pianos, strings, choirs, brass, synthesizers, guitars, organs, etc. When it comes to those sounds, well...they are awesome, no question about that. Kurzweil has always been known for its ability to produce full, resonant sounding instrumental sounds and the CUP2 does not disappoint in that way. Big, lush, and beautiful tones. In fact when I play on that stiff key action, it's not as much an issue when playing those sounds because your not playing in a regular acoustic piano style which would need a better action. However, a better more realistic easier to play key action would make playing the other sounds much more enjoyable.
