About Casio PX S1100 and Casio PX S3100

The Casio PX-S1100 is a digital piano that was introduced in 2021. It is part of Casio’s Privia line and is designed to be portable and affordable.

Design and Build Quality

When choosing a digital piano, it’s important to consider the design and build quality of the instrument. Both the Casio PX S1100 and the Casio PX S3100 are well designed and built to last, with high-quality materials and attention to detail. However, the Casio PX S3100 features a more straightforward and modern interface especially with the display that is missing on the lower model, making the piano easier to navigate.

Sound Quality

One of the most important factors to consider when choosing a digital piano is the sound quality. Both the Casio PX S1100 and the Casio PX S3100 are equipped with Casio’s AiR Sound Source, which provides incredibly realistic and dynamic sound. This technology is capable of reproducing the sound of a concert grand piano in stunning detail.

In terms of sound quality, both pianos are very similar and produce a rich and full sound that is ideal for a wide range of musical styles. However, there are a few differences between the two that may make one model a better choice for you than the other. For example, the Casio PX S3100 features a greater number of instrument sounds (700 versus 18), giving you more options for different musical styles. Additionally, the PX S3100 has slightly better acoustic piano samples than PX S1100.

Keyboard Action

Another key factor to consider when choosing a digital piano is the keyboard action. This refers to the feel of the keys and how they respond when you play them. A good keyboard action will mimic the feel of an acoustic piano and provide a comfortable and responsive playing experience.

Both the Casio PX S1100 and the Casio PX S3100 are equipped with fully weighted keyboards that provide a great playing experience. The key action is Smart-Scaled Hammer with faux ivory and ebony finish which feels identical on both pianos. If you are used to high-end digital pianos, the key action is on the lighter side which is fine for most people, but probably less satisfying for seasoned pianists.

Connectivity and Features

When it comes to connectivity and features, both the Casio PX S1100 and the Casio PX S3100 are well equipped. Both models feature USB connectivity, allowing you to easily connect to a computer or other devices. Additionally, both pianos come equipped with a range of features that make them ideal for both performance and practice.

One of the main differences between the two models is that the Casio PX S3100 features built-in editable DSP effects while the lower model only has some choruses. This feature gives freedom for experienced piano players who want to play with their creativity as the effects quality is excellent, but probably too complicated for beginners.

When it comes to price, the Casio PX S3100 is generally more expensive than the Casio PX S1100. This is due to the additional features and capabilities of the PX S3100, including the larger sound library and more features. However, both pianos are reasonably priced compared to other high-end digital pianos and offer excellent value for money.
