Hi there! Welcome to the Merriam Pianos CZcams channel. We’ve got another comparison for you here as we’ll be looking at how the Casio Privia PX770 stacks up against the slightly more expensive Casio Privia PX870.
We’ll go through all the critical differences between these two instruments, so hopefully, by the end of the video, you’ll know which one’s right for you if you’ve been comparing these two models.

Piano Overview:
You can essentially think of these two Privia’s as Casio’s response to hugely popular models from competitors, such as Yamaha’s YDP series and Kawai KDP series. The home digital piano market has continued to grow substantially over the last few years, so it’s no wonder Casio has made great efforts to claim a share of this part of the market.
The vast majority of differences between the PX770 and PX870 are sound-related; both in terms of signal processing and amplification, Price-wise, the PX870 costs an additional $400 CAD over the PX770. Now we’ll dive into some specifics.
Piano Sound:
Starting with polyphony, the PX770 features 128 notes of polyphony, while the PX870 doubles it up with 256 notes. What does this mean for the playing experience? It’s fairly subtle, but there is a slight difference with the PX870 sounding thicker.
In terms of the speakers, the PX770 utilizes two 8 watt speakers (16-watt speakers), while the PX870 uses 4 speakers, driven by 40 watts of power. The extra speakers in the 870 provide more detail in the higher frequencies, and of course also a fuller sound due to the extra output power.
Both instruments have the same selection of onboard tones, with a total of 19. There’s a menu labeled on each instrument above the keyboard, which while not aesthetically pleasing, does make for fast navigation of the different tones and other features. The additional tones including electric pianos, organs, strings etc. are quite nice across the board.
In terms of other differences, the PX870 does offer up a few extra sound related parameters, such as string resonance, which does contribute to a better tone.
Do these sound-related differences justify the extra $400 spend for the 870? If you’re mostly going to be using the piano with headphones, probably not, since the differences will be mitigated. That said, if you plan on using the instrument with the speakers primarily, you should strongly consider springing for the 870.
Piano Action:
The actions on both of these instruments are exactly the same as they both feature Casio’s 88-key, Tri-sensor Scaled Hammer Action Keyboard II (Simulated ebony and ivory keys). The triple sensor means this action is capable of accurate MIDI output.
This action doesn’t feature escapement, which probably won’t be a big deal to most looking at one of these instruments anyway.
The texture and the feel on the top of the keys, as well as the key dip, do feel somewhat different than what most will be used to. This might take a little bit of time to get used to as the texture is quite exaggerated. This does go away over time as the keys get played.
Casio has done a great job of improving on the mechanical click noise of the keys, which was a common complaint with their actions in the past. This action is much quieter, which usually lends itself to greater longevity and durability.
Piano Features:
The cabinets on both of these pianos are quite similar, and both are available in black as well as white. The quality of the cabinetry is seemingly identical between both instruments.
Conclusions:
Both of these instruments deliver a great value for the price. They both have a good touch and piano tone that’s on par with offerings from competitors. The PX770 will compete admirably against the Roland RP102 and Kawai KDP70 for example, while the PX870 will be positioned against pianos like the Yamaha YDP144 and Kawai KDP110.
Thanks so much for watching!

Stu does the best keyboard reviews out there, and I've watched a lot of them. Well done. It's always great when a new one comes out.
His review is always great
excellent detailed video.
Another excellent review thank you! “Piano comparison with Stu Harrison”! 😁
It's clear Stu loves playing both improvisational jazz, pop tunes, & classical pieces. He's quite accomplished. I love his reviews, so easy to understand. You don't have to be a professional pianist to understand his reviews.
I know Stu appreciates that immensely! I'll be sure to pass on these kind words to him. Thanks so much for tuning in! :)
Great video! 🙂
Thanks! We appreciate it! :)
Hi, do you know if the keyboard and touch response are identical in Privia models (770, 780, 870) an Celviano (270 and 470)? I was reading the specifications at the Casio website and It seems they are identical, but sellers are saying the oposite.
Good evening friend. I can’t find this info anywhere, can you tell me if it’s possible to ADD new tones to this piano? Like synth tones, fx tones, etc.
I appreciate all your reviews @Stu and @Merriam! Very helpful! Can you please review the px-780 and compare to px-870? It's quite a bit older, but offers so many features far beyond any other at the same price point! I'd really like to understand the difference in sound.
Please make a review on roland go piano
The first one you played sounded very nice. I feel I can hear the improvement in the 870. To my ear the 870 sounds closer to a parlor grand. The 770 is perfectly acceptable but slightly less authentic as compared to the 870. Again this is through my Lenovo laptop speakers. As usual, your playing is absolutely lovely and shows off these instruments very well. I have my order in for a Kawai es920 but I'm concerned the voice quality may not be up to par with the modeled voice Roland upright or even these two Casios which sound very good. I always feel that the es920 Kawai has somewhat of the earlier Casio PX-150 type of sound which is a long way from the quality of Pianoteq voices, however the Casio 870 is extremely impressive and on par with Pianoteq. Key height of the black keys can make an extreme difference as to how any action feels. I believe the PX-150 and 160 actions are probably the same but the 160 has more texture on the key tops. Again "let-off" is completely unneeded on a digital action. It's simply a marketing gimmick.
Thanks for the great video! I'm still trying to make my decision between the px-770 and the px-870, so this video has been very helpful! One question: The 870 seems to have a back cover that the 770 doesn't have. Does this do anything in terms of stability of the piano or is that only for aesthetic reasons?
Hi! Brent from Merriam Music here! Glad to hear the video was helpful! It does add a little bit of extra support/solidity, but it is very minor and mainly aesthetic in my opinion. :)
@@MerriamPianos Thank you so much for your response! Aesthetics or not, I ended up getting the px-870. I'm very happy with it so far :-)
Hello I’m a fan of your videos. Very informative. I’m looking at buying a digital piano. First idea was Casio CDP S160 but now also looking at these two. Can you tell me which one is better option please? Don’t care much about the price difference between the three, just talking about quality overall. Thanks
Hi! Brent here! As one may expect, the more you increase the budget, the more superior the features and musical offering will be. From this perspective, the PX870 is the top performer amongst these options as the price tag suggests. It is the sonic experience of the more powerful speaker system that really sets the PX870 apart from the other options to me. It really presents Casio's excellent piano samples in a powerful and impressive way. :)
Hi. It's been mentioned in a few places that the Casio action has a shorter pivot point than the other popular brands. Are you able to achieve a good level of dynamic control when playing towards the back of the keys despite this?
Maybe Stu will play one of his beautiful piano stylings on the 870.
Sure, the px-1000. But this has a different action, the same things won't automatically apply.
PX-870, the keys are slippery, and some of those keys make a plastic clicking sound when released. The keys also do not bounce back quick enough.
Has anyone tried adding a 3rd party Bluetooth transmitter to these models? I am curious if that is possible using one of the 1/4" jacks on the PX-770.
Casio does offer their WU-BT10 wireless bluetooth transmitter, but it is only compatible with the following models:
CT-S1000V/CT-S500/CT-S1/CT-S400/CT-S410/LK-S450/PX-S1100/PX-S3100/PX-S7000/PX-S6000/PX-S5000
oh man the 870 sounds great
It really does! The combination of speaker power/fidelity mixed with an excellent piano tone provides it with a wonderful sonic experience. :)
on the 770 can you plug it into external speakers for a loud gig or something like that?
Hi there! The PX770 does not have separate line outs, but the headphone output can also be used as an output, which allows you to plug the PX770 into external speakers or a PA system.
What about a review on the Privia PX 780?
I second this! Please review and compare to px-870!
Unless you play 128 notes between pedals, it should be fine with the 770.
can someone please help me? my px 770 middle c is lower than it should be and the c1 is in it's place
It sounds like some type of setting (duel, transposition, etc.) has been unintentionally adjusted. I would recommend doing a factory reset to restore the default settings.
The open lid gimmick is gone from the 860?
The PX770 and PX870 do not have that feature. Other models, such as the AP470 do though. :)
this one or donner ddp100? I am 40. I used to play and study classic music everyday in my teens. then picked up the guitar and dropped the piano. Now I have time and space for a piano. It has to be WHITE. Any suggestions anybody?
Hi! Brent here! I have played a few Donner models. While some of their models have some really nice design and aesthetic qualities, as far as the piano tone goes, I personally think an instrument like the Casio PX870 will be superior. However, it really comes down to subjectivity and personal preference.
price and aesthetics of donner are appealing. but i don't want to end up with regrets. also i just realized you are in the GTA. I should visit@@MerriamPianos
@@MerriamPianos thank you. i just realized your in toronto. I might just visit. have a nice day.
