Yamaha DGX-620 vs 660: A Head-to-Head Comparison

To be honest, when I compared these two pianos, the Yamaha DGX-660 won by a long mile. The DGX-620 is one of the most basic options in the DGX series, so you lack a lot of the features from some of the other models, which is the trade-off you get when you buy a cheaper digital piano.

When reviewing these pianos, I looked at the tone, feel, and piano features of both instruments. And in each category, the DGX-660 won with a score of 3-0. That said, this doesn’t mean that the DGX-620 is a bad piano. In fact, it’s still a great option at its price point.

I get into more details in the section below so you get a clearer picture of who these pianos are for and which one is best for you.

Tone

The winner: Yamaha DGX-660

The tone or the sound of a digital piano is probably one of the instrument’s most important features, which is why this is the first thing I checked out. And unsurprisingly, the DGX-660 easily took the point as it has a massive sound library powered by a top-tier tone engine.

+Tone Generation

The Yamaha DGX-660 comes with the Pure CF Sound Engine. This sound engine is powered by high-quality samples recorded from Yamaha CF Grand Pianos, which are some of the most sought-after acoustic pianos right now. This makes for a crisp and clear piano tone that you won’t be able to find in this price range.

On top of that, it contains hundreds of tones from the XGlite Suite, which contains a lot of unique sounds. Granted, the sounds from this tone generator aren’t as high-quality, but they are definitely great if you need a wide variety of sounds.

The Yamaha DGX-620, on the other hand, only uses a simple sample-based tone generator. It doesn’t use the same samples as the DGX-660, so you don’t have the same realism, clarity, and brightness with this piano.

This was a slight letdown for me as the piano comes from one of my favorite Yamaha product lines. That said, if you’re a beginner looking for a simple practice piano to use at home, the piano sound is still pretty decent. It isn’t ideal for recording or for performances, but it definitely does the job as a home piano.

+Sound Library

One of the things that surprised me with the Yamaha DGX-620 is that it came with 500 voices. Most pianos at this price point only come with a handful of voices, but the DGX-620 really went the extra mile on this one. But again, the sound quality on this piano isn’t the best because Yamaha didn’t load it with the best samples.

So, while you get quantity, you don’t exactly get quality.

The DGX-660, on the other hand, has an even bigger sound library with over 550 sounds. This gives you just about everything you need as a pianist. And while some of the voices could be a bit more realistic, others sounded great and are definitely voices you can use while gigging and playing live.

The DGX-660 easily won the point in the tone comparison because it has a better tone engine and a bigger sound library. So, if you have the extra money, you might want to spend it on the DGX-660 instead of the DGX-620.

Feel

The winner: Yamaha DGX-660

The next feature I looked at was the feel. And since the Yamaha DGX-620 only comes with basic weighted action, it lost to the DGX-660. This model comes with a sophisticated hammer action system and slightly textured keys, allowing it to feel much closer to an acoustic piano.

+Hammer Action

I really liked that the DGX-620 came with weighted keys. Most entry-level pianos don’t even bother to add weight to their keys, so it was a nice touch. However, while the hammer action system of the DGX-620 would be enough for beginners, it isn’t as realistic as most pianists would like it to be.

This is why I rank the DGX-660 over the DGX-620. The DGX-660 comes with the GHS or the Graded Hammer Standard, which is one of the best hammer action systems to come out of Yamaha. This system replicates the small differences in the weight of a piano’s keys, allowing for a much more realistic feel.

On top of that, the black keys on this piano are coated. While they don’t exactly feel like ebony, they come fairly close. The Yamaha DGX-660 isn’t the most realistic feeling digital piano on the market, but it does a much better job than the DGX-620. 

Piano Features

The winner: Yamaha DGX-660

The last thing I checked out was the extra piano features. These include polyphony, playing modes, and more. And as expected, the Yamaha DGX-660 easily won this comparison as well. Since this is the more expensive option, it has way more features, allowing for a much more versatile piano.

To start, the DGX-660 comes with 192-note polyphony, which is miles ahead of the 32-note polyphony available on the DGX–620. This allows you to play more notes simultaneously without sacrificing crispness and detail. While the polyphony on the DGX-620 is enough for most beginners, it is significantly lacking when you start playing more advanced pieces and adding the sustain pedal.

And since the DGX-660 has more polyphony, it can handle the various playing modes more often. You can do a lot with the DGX-660, such as blend two voices, split the keyboard, or even creating a twin-piano set up for piano lessons. You can do some of these things on the DGX-620, but since it only has 32-note polyphony, you can’t make the most out of these features.

Yamaha DGX-620 vs 660: The Similarities

These two pianos come from the same product line so you can expect a lot of similarities. To start, they both come with massive sound libraries. This allows you to experiment with different voices to fit various styles of music. And even if the voices on the DGX-660 are higher quality and more varied, you still get more than enough with the DGX-620.

On top of that, both pianos come with relatively good effects set. The effects allow you to take full control over your tone and tweak it according to your needs. So, you get a lot of functionality from both pianos. But since the DGX-660 comes with way more features, I had to dub it the winner.
