Hi,

Is the Yamaha p155 still a good option for buying a digital piano, even with the new release of the p255? I'm looking at the package deal at Kraft with the furniture stand and seat.

My budget is about US $1000-1200, I might be able to get the p255 at $1300, but it would really be stretching it. I took 7 years of piano lessons as a kid, and now in my 30s I'd like to get back into it. I bought a cheap keyboard but I can't stand the sound of it, so I'm looking for something that plays well and sounds good.

I saw a couple of youtube videos of the p255 but was not overly impressed with the sound compared to the 155.

I tried the 155 in the store and liked it, but haven't had a chance to try a 255. Are the upgrades worth the extra money?

Thank you.

The P255 has the same action as the P155, and the differences appear to be minor and largely cosmetic. If it were me buying a new DP at this price point today, I would get the P155 for $300 less, and wouldn't think twice.

You should be able to negotiate for a better price on the P155. Offer them a deal you couldn't refuse. smokin

Have you tried out any of the Casio Privias? You get a lot of bang for your buck and might be good just to compare. Also the Kawai ES100.

The P-255 does have twice the polyphony of the P-155. I personally think that's major!

I think you should see how low you can get the P155. It's deprecated now so they should be eager to get it off their hands. Good piano.

I'd disagree with Speedy. Polyphony is the number of sounds that can be played simultaneously. In very early pianos you could play several big chords or lots of sustained notes and some would drop out. However, that is not a concern in modern pianos. There are many, many P155 owners here but I've never heard of anyone having note dropping issues with that model. Polyphony is not a binding constraint so increasing it won't affect your playing experience.

It is possible (but by no means certain) that the more advanced tone generator of the P255 uses more "polyphony" for a given note, which is why they had to increase it. However, polyphony numbers themselves don't give you any information about this. No current digital piano easily runs out of notes, so polyphony is a marketing statistic that is best ignored--it isn't calculated the same way across manufacturers or even models anyway.

They are both solid instruments in their price range. Try them out in person. In one of the places I am frequenting, I'm using a P155 for practicing and it works. However if buying new I'd probably want to compare with the P255, "hands and ears on".

Another nice new feature of the P255 is key sympathetic resonance which the P155 lacks. Again, not a big thing, but perhaps a nice little detail.

polyphony and key sympathetic resonance and the like are big things when it comes to trying to delineate your expression in fragile pieces like girl w flaxen hair by debussy. I know a lot of us are just amateurs and perhaps even beginners for the longest time but we all have the likening to play such expressive pieces.
there is a big difference in sound expressiveness when it comes to 64 , 128 or even to 256 polyphony. .and it doesnt require a pianist to appreciate those nuances or try to bring out the nuances in his or her play.

that said, p155 is a great keyboard for practice. I would not even hesitate to get one if I was in the market to get a 850 dollar keyboard

I wish you wouldn't spread misinformation like this.

Sympathetic resonance and other features of the tone generator can make a piano more expressive. Polyphony cannot. Polyphony only makes any difference if so many notes are played that you are getting drop outs. You won't get that on the P155 or any other piano of similar quality. Not unless you are layering multiple voices and keeping the pedal down and playing up and down the piano in an unusual fashion. There are only 88 keys on a piano. Even if you double count for stereo, you can't approach 128 notes while playing real music.

TL;DR: Polyphony doesn't affect expressiveness or nuance, so don't say it does.

You should definitely sit down with a Casio PX-350.

Hear hear!

I've never had trouble with a "paltry" 64 polyphony, and the boards years ago were rife with posts claiming only rare problems with 32 polyphony.

High polyphony numbers are just marketing hype. They're the piano equivalent of tail fins on a '59 Buick.

Well, more polyphony does help when you are layering two sounds (eg: piano and strings), when using the new rhythm sounds...and possibly in generating the string resonance. Anything that is an additional sound will normally use extra sample playbacks.

I had the chance to see and play the P-255 today. As the owner of a P-155, I cannot say that I saw anything that really stood out, and the price is a good $400 more here. If I were in the market for a piano of that type, I'd probaby snap up the P-155 while I still can and save the price difference. Mind you once the P-155 is really gone, hopefully they'll lower the price of the P-255, or else Yamaha will have an unfortunate hole in their line of price points.

Is the GH3 action much better than the GH on p155?

Just gonna add my two cents:

I recently bought a P-255 (check the "PRICES PAID" section - you may find the P-255 isn't as costly as assumed). I know the actions of the P-255 and P-155 are supposed to be the same. To me, they don't feel identical. Close, yes - and it may simply be the "ivory feel" keytops that make the difference. If so, that's fine - because for me whatever the difference is, it's sufficient to let me enjoy the P-255 in a way I never could warm up to the P-155.

pwl,
so what in your perception is the difference between the key action of the P-155 and P-255?

With the P-155 I always felt I was pushing a lever. For some reason (self-hypnosis?) the P-255 feels a bit more lively/bouncy (in a good way), which for me comes across as more realistic and more enjoyable to play. Again I want to emphasize - I wouldn't try to make an empirical case that there's a difference (because other than the ivory/ebony key finish there may not be), but my *perception* of the two is that there is a difference. And I've learned in other areas of experience, we sometimes perceive differences that are in fact real but not easily quantified or put into a spec sheet.

Summation: I'd simply suggest that someone interested in the P-255 not automatically assume they'll react to its action/playability the same as they would to a P-155.

Some have suggested, and I'm of the same opinion, that Yamaha uses only a few generic names for their actions year after year and then fools around with the specs from model to model. So the only thing that can be said for certain about "GH" is that it's graded and has two sensors.

I agree with previous posters. Couple years ago I had the chance to compare CLP-430 and CLP-440 side-by-side, and oddly found the later to be *considerably* better. I had to double-check both manuals to make sure the only difference were the key tops, because it felt like a completely different action.

Did you really mean CLP-430 and CLP-440 (two pianos of the same generation) ?

But it's true they have different keyboards (ivory keytops on the CLP-440... like the P-255)

I just got the 155, and I'm very happy with it. I think it just sounds and feels great. Of course, I haven't played in years, but I really like this digital piano so far. A lot better then the p105, which I was also thinking about. No regrets in not getting the 255, even though I didn't try it. I like the way the 155b looks over the 255 for some reason as well.

Yep. Even though they have the "GH3" action they felt completely different to me. And I'm pretty sure it wasn't due just to different key tops. I always thought that it had to do with some external factor (like CLP-430 probably being played a lot more since it's cheaper), but now I see others noticed this too. Maybe Yamaha does have different actions under the same name, who knows.

So I would definitely check P-155/P-255 before deciding, because there's a chance actions will be more apart than one would expect with both being called "GH".

The fact that they change the action with the same name could be surprising, but according to you, they also put a change between pianos within the same generation (CLP-4xx), which could be more surprising. It seems that they changed the action when developping the GH3 with ivory keytops (CLP-440) and they did not put the improvement in the CLP-430 which does not have ivory keytops.

The P-155 and the P-255 share the same difference (ivory keytops on the P-255 only).
