An upgrade to the Yamaha DGX-650, this model aims to be a flagship of Yamaha’s “Portable Grand” line.

There are so many options to explore and enjoy that surely even those already having their digital piano would give upgrading a serious thought.
Yamaha DGX- 66O Builth and design
As the popular saying goes, “The first impression is the last impression”. This digital piano impresses with its first look, without even getting into the specifics of using it. The keyboard with an impressive LCD screen, a host of controls, and perched atop a stylish stand make for a grand picture by itself. The synthetic wooden grain on the stand gives it the feel of an authentic wooden stand on a grand piano.
Although the DGX-660 is a part of the Portable Grand line, we wouldn’t call it very easily carried. The keyboard is pretty big and heavy compared to other models in the line and digital pianos from the P-series. Weighing close to 46lbs (20.8 kg) without the stand and nearly 61.7lbs (28 kgs) with it, it is not very convenient to move around. However, the latter doesn’t come anywhere close to the DGX-660 in terms of sounds, features, and connectivity options.
The Yamaha DGX-660 is in keeping with its features. Without the stand, the digital piano comes to 55 X 17.5 X 5.7 inch without the stand and 55 X 17.5 X 29.9 inch with the stand, which is pretty standard for 88-key keyboards.
The DGX-660 has a contemporary-looking design with nice wooden elements (side panels, stand). The keyboard comes in two standard colors – black and white. The white keys have a glossy finish, while the black ones are matte, which will prevent fingers from slipping when they become moist.
The Yamaha DGX-660 also comes with a matching stand. It’s well-built and sturdy enough to hold this rather large keyboard.

Yamaha DGX- 66O keys
The keys are what make up the keyboard – the sound, the feel, and the ease of use are what make a user make up their mind about buying or not buying a particular keyboard. Yamaha hence in this model they have gone full out with what they could provide with their keys.
The DGX-660 features a touch-responsive keyboard with 88 fully weighted keys.
The Yamaha DGX- 660 has an action called the Graded Hammer Standard (GHS), and it’s the same keyboard action that will be found in the Yamaha P-45 and P-125 digital pianos. GHS refers to the fact that the keys in the lower range have a higher weight that gradually goes on decreasing as it moves towards the higher range. This makes the keys in the higher range much lighter, quite similar to an acoustic piano. This will help you develop a good technique needed for performing on an acoustic piano.
The keyboard of this premium model has volume sensitivity, meaning the force and speed with which you play the keys has an impact on the volume of the keys. There are 4 settings to achieve this- Soft, Medium, Hard and Fixed. Let us take a look at each of these settings.
The keys of the DGX-660 are made of plastic, which is true for all the keyboards in this price range.
The white keys have a glossy finish, while the black ones are matte, which will prevent fingers from slipping when they become moist.
