Hi Folks,

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.

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.


My current instruments: Yamaha CLP-645, Clavia Nord Stage88, Casio Privia PX130

You're not the only one who wonders. I think it has to do with the "Features" list -- many potential buyers don't understand how important amps and speakers are, or how much good ones cost. And the "Features" list doesn't let the maker say:

. . . "This is only two lines, but it's _really important_, and it cost us $300 at the factory!"

If you have a Nord Stage, you know how to connect powered monitors to the Yamaha . . . "beautiful living room" be damned !<g>

PS (after checking specs) -- it's got 150 watts _per channel_, tri-amped. Plenty of power. The weakness seems to be the 16 cm woofer. It might be hard to build a good enclosure, in that slim cabinet:

. . . How are the speakers arranged ?

. . . If the weakness is in the bass, could you add a subwoofer?

I liked your playing. Weak speakers is a typical complaint I play mine mostly with headphones.

Is the problem the direction in which the speakers project the sound? On my DP I have rear-facing speakers. Probably fine if playing for an audience but lousy if the piano is standing directly at a wall and when playing for myself. Just ouf of curiosity.

Super playing. I wish . . . The piano sounded nice; maybe you could de-tune it to that of a typical acoustic. Many do this, I think it takes away the clinical edge of digital technology.
All acoustics are notorious for uneven sound, variation from note to note, extraneous noises from keys, pedals. You might tweak them up, too.
You'll grow to love the sound eventually, I think.

Very good Bach playing. Probably the speakers are not the best, but samples seem very good in your recording. Maybe a little dry sound, try to add reberb or similar processing if you can. Thank you for your review.
