I promised in a previous thread that I will share my thoughts on the instrument of my choice - the Yamaha CLP-645. Those who followed me know it took a little while I could make a decision. I was particularly looking at Yamaha models CLP-645, 675, 685 versus Kawai CA78 (98). I liked the Kawais and I liked the Yamaha 685 but I had to make a compromise due to financials so I chose 645. It arrived a month ago so I had some time to spend with it, here's my thoughts about it:
The CLP-645 is a very neat looking digital piano it gives you the impression of a well-made product, it's sturdy built and the materials look and feel of quality. The key action is really good, fast and responsive, a bit noisy though - only heard at low volumes. Unfortunately I didn't have the chance to try this action alongside the CLP-685 GrandTouch in the same room. As far as I can remember the action in the pricier model felt great too, I wouldn't know which one is better for me.
The weakest point of my instrument is clearly the internal sound, just not in par with the capabilities of this piano. I wonder why they put lousy speakers in a $2500 DP. The CLP-685 sounded amazing in the store. Fortunately it's not so much of a problem for me as I seldom play at high volumes and the sound via headphones is nice. One remark here: there is this IAC (Intelligent Acoustic Control) roughly equivalent to Loudness function on stereo amps. I found that if I turn it OFF the sound is more natural and less boxed in.
The bluetooth functionality is very useful, I already made some recordings and I tend to use my phone to play backing tracks for me while I play - very convenient although nothing to be very excited about in 2019.
Finally about the sound: I know this is even more subjective than key-action so I made a recording for you. N.B. I'm not a classical pianist but the playing feel on this piano is so great I sort of got in the mood to go back to my classical pieces. This is the CFX Grand voice.https://drive.google.com/file/d/1yWqGfEoj482GwV1a9nS1YupNXgcqfOr9/view?usp=sharing
I like the sound of the CFX, the Bosendorfer is useless, as are most of the other sounds but I don't care about them at all since I only need a piano at home. For other sounds I have the nord stage.
To sum it up I think I have made the right choice: I picked an instrument I like very much and that satisfies most of my expectations. The next best thing would have cost me almost double (CLP-685) or I would have to be worried about constant quality issues (Kawai).
Let me know your thought and don't be too hard on my playing, it's been like 15 years since I last played classical music.
