Austin Bazaar is an authorized Casio dealer.
The Privia PX-870 is the flagship of the world-renowned Privia line of digital pianos, designed to give you a true grand piano experience. With authentic piano sound and feel, a stylish modern design, and the powerful new Sound Projection speaker system, the PX-870 is a brilliant instrument for inspiring brilliant performances.
The PX-870's award-winning AiR Sound Source includes a new four-layer stereo grand piano which comes alive with realistic damper resonance, simulating the entire body of the instrument, not just the strings. The piano also includes key action sounds, key off simulation, adjustable hammer response, and a lid simulator with four positions. The PX-870 also includes string resonance, which exposes the sympathetic harmonic relationships between vibrating strings. Along with adding to the subtle beauty of the sound, this adds authenticity when playing works by Debussy, Ravel, and other composers who wrote with string resonance in mind. The PX-870 features a variety of 19 instrument Tones, with the ability to layer and split them as needed. With a generous 256 notes of polyphony, you can rest assured that even the most complex performances will sound perfectly natural.
The acclaimed Tri-Sensor II Scaled Hammer Action piano keys give you the expression your performance deserves. The simulated ebony and ivory textures give you an authentic and comfortable touch, combined with an innovative hammer action that is accurately scaled across the entire key range. Adjustable touch sensitivity and hammer response allow customization to suit any playing style.
The PX-870's innovative new Sound Projection system fills the room with rich, detailed sound. This powerful 40-watt, 4-speaker system is designed to envelop the listener and audience with sound emanating from various places on the instrument, just as it would on a traditional grand piano. The Volume Sync EQ ensures that you hear a balanced, clear sound across the entire frequency range, at any listening volume.
The PX-870's convenient features are useful at home, in a lesson studio, or anywhere else. You can connect two sets of headphones using the 1/4" jacks on the front panel, making the PX-870 ideal for quiet practice. A unique Headphone Mode optimizes the PX-870's sound for headphone use. Duet Mode splits the piano into two equal pitch ranges, allowing a student and teacher to sit at the same instrument.
60 songs are included in the built-in Music Library, with room for ten additional songs of your choice. You can also record your performances using the PX-870's two-track MIDI recorder. Concert Play allows you to play along with ten recordings of well-known orchestral pieces, with the ability to either listen to the piano part or silence it so you can play it yourself. To facilitate practice, you can even slow down these recordings without affecting their pitch.
Designed to compliment any décor, the PX-870 is available in either a black or white finish. Its compact, elegant cabinet with sliding key cover adds to the beauty of any room. The easy controls are located to the left of the keys, allowing you to play without distraction.
The PX-870 connects via class-compliant USB to any PC, Mac, iOS, or Android device, with no drivers or installations needed.

Having spent some time with it, I will comment. Note that I am becoming a piano bigot, having been spoiled by 2 minutes at the only known working Germain grand. Bought this for practice; the only other instrument I have is a "bright" Astin-Weight, while I wait for re-birth of my 1936 Steinway Model S.
Furniture: Sort of cheap but not bad.
Assembly: No big deal.
Portability: 2, not 1 people! I did manage to push it up the stairs and get it together by myself, but this is not recommended.
Configuration: Have been stuck trying to use a lower-end Casio with loose switch for a damper. No way that is acceptable. This is much better.
Voices: Interesting to play with.
Recording: #1 Book not accurate you have to tinker to learn how to record to USB. #2 Volume on computer file too cotton picking low must go use Audacity to crank it up as far as you can without distortion.
Action: Ha! PX-870 does not pretend to have a real action you have to spend more for that, much more. It is a bit heavy and not really possible to use to get expression needed. Perfectly fine if you just wanna hit the most notes and be loud. And plenty good if you are just trying to train fingers to hit where you want.
Bottom line: Don't like it but consider it to be quite a deal for the price and it is useful. Dealing with Austin Bazaar was just great too.
Casio Privia PX-870 has all the functionality of Casio's flagship PX-160 but comes with a built-in stand and pedal unit. It's designed to look nice in your living room or home. It offers plenty of advanced functionality, more than Casio's similarly designed but less expensive PX-770 digital piano. This particular bundle includes a furniture-style bench along with some instructional materials. If you're looking to invest in a digital piano with advanced features as well as a furniture-style design, this PX-870 digital piano bundle is the full package. Casio PX-160 is more affordable and compact but offers less functionality and lacks the furniture-style design of the PX-870. Comparable models would be the Yamaha Arius series of pianos, or the Yamaha DGX-660, though those tend to be more expensive and larger in size.
Wonderful piano, great customer service and very fast shipping!
Great sound, love the more natural ebony/ivory feel. Fast delivery, highly recommend this product and company!
