Choosing a digital piano under $1,000 can feel overwhelming, especially with trusted names like Casio and Yamaha in the mix. Two of the most popular options in this price range the Casio PX-S1100 and the Yamaha P-125 both offer excellent sound, fully weighted keys, and impressive features. But they take very different approaches to design, feel, and functionality. Here’s a closer look at how these two keyboards stack up and which one might be the better fit for your style and needs.
Casio PX-S1100
The PX-S1100 is the successor to the PX-S1000, refining its minimalist, ultra slim design while upgrading its internal components slightly for improved speakers and Bluetooth capabilities. It’s one of the slimmest digital pianos on the market, and looks more like a high end piece of tech than a traditional keyboard. The glossy touch panel interface replaces physical buttons for a clean, futuristic feel.
Despite its compact size, the PX-S1100 surprises with its Smart Scaled Hammer Action, which is both expressive and smooth. While the action is slightly lighter than some might expect, it's responsive and consistent across the range. The AiR Sound Source delivers a warm, detailed grand piano tone, and Bluetooth audio support is a huge plus letting you stream backing tracks directly through its built in speakers.
Portability is another big win here. At under 25 pounds, it’s easy to carry to rehearsals, gigs, or store in small spaces. Add in USB MIDI, a class compliant USB interface, and compatibility with Casio’s Music Space app, and it becomes a strong option for both casual players and mobile musicians.
Yamaha P-125
The Yamaha P-125 takes a more traditional approach. It has a clean but conventional look with tactile buttons and a simple layout. It’s slightly heavier and bulkier than the PX-S1100, but still very much in the portable category. Where the P-125 really shines is in its Pure CF Sound Engine, sampling the iconic Yamaha CFIIIS concert grand. The result is a bright, clear, and lively piano tone that cuts through a mix beautifully perfect for jazz, classical, or pop settings.
Its Graded Hammer Standard (GHS) action is heavier than Casio’s, mimicking the feel of an acoustic piano more closely, especially in the lower register. Some players find it a bit stiff, while others appreciate its familiarity and weight.
Although it lacks Bluetooth, the Smart Pianist app (connected via USB) offers excellent control over the instrument’s sounds and settings. The internal speaker system is also a standout: with two woofers and two tweeters, the stereo image is impressive for its size, and delivers punchy, room-filling sound.
Which One Is Right for You?
If you value portability, modern design, and wireless audio, the Casio PX-S1100 is hard to beat. It plays beautifully, and offers a sleek experience that’s perfect for apartment dwellers, mobile musicians, or tech-forward players.
On the other hand, if you prefer a more traditional piano feel, a brighter, more expressive sound, and a no nonsense, tactile interface, the Yamaha P-125 is a tried and true choice. It may lack some modern features like Bluetooth, but what it does, it does well and reliably.
Final Verdict
Casio PX-S1100: Best for players who want style, portability, and wireless convenience.
Yamaha P-125: Ideal for those seeking a classic playing experience with rich, bright tones and a heavier action.
Both pianos are excellent in their own ways but it really comes down to what kind of playing experience you’re looking for.
