((Roland Digital Piano Comparison)) What's the difference between HP603 DP603 HP605 LX7 LX17

DP603 is also a wood keyboard,
(CA17, CLP645, DP603)
Most often used to be compared together,
In fact, I think Roland's products are the highest you can buy DP603.

Roland's wooden keyboard electric piano,
What's the difference between having DP603 HP603 HP605 LX7 LX17 Kiyola GP-607?
All, all, all, one, mold, one , like!

The keyboard stringing system of DP603 is called PHA50
The PHA50 is also Roland's highest-end keyboard.
A more expensive model, and there won't be a better keyboard than the PHA50,
More than 60,000 DP603, all the way to more than 40,000 LX17, and even 60,000 V-Piano
All use PHA50, the same set of keyboards.

And the digital functions are all the same.

in other words:
Just changed the appearance, shape, paint, and increased the wattage of the speakers.
The most important nature of the keyboard system has not been improved,
So why would you pay extra for higher-end products?
DP603 already represents everything!

Other high-end products are sold in packaging, as well as the size of the speaker, (you can buy a better one for external connection)

So what do you recommend for the LX17?
If the keyboard feel is not improved,
Spend an extra 30,000 yuan to get a beautiful piano paint shell,
There are also higher wattage speakers.
(That's it? Just buy a better speaker to connect externally)

So I think Roland's products can only buy DP603 at most.

The other two brands that specialize in pianos are not like this.

KAWAI and YAMAHA, at every price point, provide different grades,

KAWAI's wooden keyboard systems are:
RM3, GF2,
And Hybrid's NV10 (complete grand piano stringer)

Yamaha's wooden keyboard systems are:
NWX, GrandTouch,
And Hybrid's NU1 (complete upright piano action)
And Hybrid's N1~N3X (complete grand piano strings)

I will introduce it later when I have time.
