Digital Piano - Review & Best Value Feature/Price Comparison (Yamaha, Casio, Roland, Kawai, Korg)

Web popularity decided the brands for this review – Yamaha, Casio, Roland, Kawai, and Korg lead the list. Yamaha is the prolific manufacturer with over 200 different digital piano models. Casio clocks in a distant second with fewer than fifty models. Roland, Kawai, and Korg are much more modest in their options. Yamaha bags the undisputed brand premium, the fruit of extensive investment in research and development over a long period of time.

A note on pricing:

Most digital pianos are sold online or through national retailers. This convenience allows consumers to do comparison-shopping and realize lower margins compared to acoustic pianos purchased through a dealer. Of course, for acoustic pianos, dealers provide valuable service – the weight of the piece (upwards of 500 pounds), the professional tuning they require and setup make online and national retailing take a rear seat. On the other hand, the weight of digital pianos rarely exceed 150 pounds (even the cabinet models that look like an acoustic piano), and requires no special tuning or setup thereby diminishing the services of the dealer. That said, for the high-end cabinet digital piano models, some consumers prefer the services of a dealer for a hands-off transaction.

While the Internet and national retailing has allowed for freewheeling for the consumer, the piano dealers have been hammered by revenue loss. With the market penetration achieved by the digital piano manufacturers, acoustic piano sales volume has declined. To stem the bleeding, piano dealers applied pressure on piano manufacturers for dealer-exclusivity. As a result, in the USA, only Yamaha’s portable piano models and the ARIUS/YDP cabinet piano models are available both online and through retailers. The remainder of Yamaha’s pianos (Clavinovas and MODUS) is available only through dealers. Similar agreements apply for higher end models of Roland and Kawai. In Europe and other parts of the world, this dealer-only policy is not applicable. In the comparison spreadsheets below, we include both the list price and the best price online – for higher end models, these prices are based on what these go for outside the US.

Variety and choices are aplenty in the cabinet digital piano models. Majority of Yamaha’s 200 and counting piano models along with Roland’s and Kawai’s fall in this category. Within this general category, there are three sub-categories:

1. Budget models,
2. Mid-end models, and
3. High-end models.

The series-choices from each manufacturer are:

1. Casio – models only in the low budget end of this category.
2. Yamaha – several models in all three of these sub-categories (ARIUS YDP, Clavinova CLP, and CLAVINOVA CVP & MODUS).
3. Roland – several models in all three sub-categories – Digital Piano (DP, PT, HP, and RT series models), Digital Intelligent Piano (KR-series models), and Digital Interactive Piano (HPi series models). In general, the budget models retail under $1500, the mid-end models under $5000, and the high-end models above $5000 with some overlap.
4. Kawai has several models in all three sub-categories – Digital Piano (CN, CE, and CE), Concert Artist Digital Piano (CA-series models), and Digital Ensemble Piano (CP-series models).
5. Korg has limited models and all of them retail for between $1000 and $2000.

Comparison:

The baseline for piano comparison is on these fundamental criteria:

• Have 88-keys,
• At-least “Graded Hammer Standard” Key Action Technology, and
• At-least 32-note polyphony.

These criteria would ensure the piano be suitable for a beginner. In general, the odds of outgrowing the piano diminishes as you opt for more features, but then costs also rise proportionally. For a beginner, it is a tough call as there is always a risk– a large percentage of beginner piano learners (especially kids) drop out within the first few years.

To narrow the number of products, we have split the comparison spreadsheets into four broad categories – two each for the portable and non-portable category. Further, Yamaha’s are not listed in the alternate spreadsheets – please refer to our exhaustive comparison for Yamaha alternates:

Summary & Recommendation:

The Yamaha's & Kawai's have a 3-year warranty and that compares very well with the Casio's, Roland's, and Korg's which have just a one-year warranty. Even so, the Roland's & Korg's enjoy good reputation among piano enthusiasts. The Casio's have excellent market share because of their value pricing. Below are our recommendations:

Best Portable Digital Piano: Yamaha P140.

Best Cabinet Digital Piano (non-portable): Kawai CE200.
