Young Chang bright and shallow

It could depend on poor regulation. Unless the hammer rail has been improperly tightened excessively. What you are complaining about can depend on a sort of regulation issue. Often dealers reduce the regulation measures because the piano seems, I say seems, easier to play and, upon first trial in the shop, the instrument is "sold" by the buyer. But then sometimes it turns out that the responses are insufficient and/or inappropriate. Therefore, the entire setup must be checked.

As far as hammer voicing is concerned, one must proceed with caution. The Manufacturer has already decided on a general voicing and, if the sound, in the listening environment, results as too bright, one can intervene WITHOUT, however, distorting the structure of the hammers.

Even, indeed, the early or late release of the dampers affects the sonority.

The mod. 121 should result in being quite sonorous and the type of hammer rail, which I know well, even if of Oriental manufacture, is adequate for the instrument and should be sufficiently compact to develop depth of sound. It remains to be seen, heard, and decided what to do.

P.S. It is appropriate to exchange opinions in the "The Piano" section.

Thank you for the answer.

So, if I understood correctly, there could be room for improvement.

My tuner didn't give me much hope...

Read. I have implemented my post

Making oneself motivated about WHY there is no hope. It is always important to qualify statements.

He replied to me that the sound is typical of this type of piano and with interventions one cannot modify it, or one can modify it but over time it returns to its original sonorities.

Ps.

I don't know how to move the post section

The analysis is quite "foggy." Everything can be modified... unless improper interventions have been made on the hammer rail, in an attempt to "soften the sound." In that case, as already stated, the hammers might have been irreversibly damaged. There is also a solution here: replacing the hammers.

Even with correct voicing and/or correct interventions on the hammers (voicing, conditioning, shaping, etc.), it is obvious that over time, through playing and resonating, the sound changes (becoming more open, more bright). One must leave, as I have already said, that margin of intervention that can be carried out during subsequent tunings, where one can work on tonal equalization.

The hammers, as I have already illustrated in other posts and in my video tutorials, must maintain a differentiated compression: greater at the apex and slightly more elastic on the shoulders, i.e., laterally. The force developed by the hammers comes from this proportion (which I have described summarily, but is much more refined...) and from the general compression that the Manufacturer decides or the technician requests during a replacement. Young Chang hammers are, originally, quite compressed, and should develop considerable sound intensity. No "negative" sound is, resolutely and simply, typical of one instrument or another!

The hammers must also have and maintain an adequate shape: slightly rounded in the bass and progressively more "diamond-shaped" towards the treble. Even improper "shaving" that flattens and/or rounds or reduces the hammers too much can produce an unpleasant sound of poor intensity.

Unless the piano is very old with very rusty strings and a poor or even negative string pressure angle on the bridges, a stiffened and flattened soundboard (I am using these intuitive terms... even if they are not quite appropriate)... (but it doesn't seem to be the case for the piano in question, which I don't think is extremely old), everything can be re-evaluated and improved. Naturally, a remote analysis alone cannot be exhaustive.
