Recently I mentioned improving the sound in the low bass region of a Steinway model "M", which I characterized as typically sounding like an old-fashioned screen door spring. I asserted that this tonal inadequacy was due to defects inherent in the "M" design and that redesign could improve the tone. Both the "screen door spring" assertion and the redesign claim were met with a degree of skepticism. There was one suggestion that all that was needed was voicing. So, I submit this sound sample. In each series of tracks the first is always a brand new NY S&S "M" on the floor of a Steinway dealer and the second is always the rebuilt "M" from the early 20th century located adjacent to the new piano. There are several tracks but really the first tracks showing note #4-C and #7-Eb make the point. If "screen door spring" isn't an accurate description of the new piano sound, I invite other descriptions. Also, I couldn't achieve this through voicing if I needled until the cows came home. If you think this is merely a voicing challenge, I'd like to know more. Here's the link: https://www.box.com/s/p1db95f7tr346dqa2em1

I'm impressed. What did you do? Rescale?

Piano #2 has noticeably better tone quality in the bass. So, what did you do to it?

I have been changing all the low single string unisons to double wrap-with smaller cores at the bottom 4 notes of Sty M's that I rebuild since the mid-1970's. They sound better and clearer than the stock specs. Now with the Paulello type O wire for cores they can be made even better because you can use less wrap and still get low enough inharmonicity and reduced longitudinal mode production. I have an article coming in the PTG Journal sometime soon titled "Hybrid Wire Scales" which describes the protocols.
I am currently rebuilding an M which converts note 27 and 28 to stainless wound tri-chords on type O wire. The piano will sound bigger and less nasal at the break. This is an exciting time for improving small piano scales with these new wire types because they offer a new way to control and minimize the negative effects of longitudinal modes.

Neither piano sounds particularly well-tuned to me, especially in the bass.

I noticed that the tuning was out as well, but point is about timbre not tuning.

Some of the issues seem to be with the bass strings, rather than voicing or tuning. Bad tuning makes it difficult to tell, as well as throwing one off when trying to evaluate other issues.

That a rescaling of the bass might dramatically improve the sound would not be a surprise to me. However that is not proven here because we are dealing with 2 different pianos of vastly different ages and presumably different hammers as well. I would expect them to sound different in any case. I would also expect them to sound different with strings from 2 different string makers, even if they are technically the same scale design. What would prove it to a finer point would be a before & after comparison of the same piano, being recorded exactly the same way.
That being said, I tend to believe your assertion it is the modified scale making the improvement. It just "sounds that way" to me, though that is hardly a scientific observation. But I have dealt with brand new pianos in which we replaced the bass strings with a rescaled set, and the difference was night and day- the "tubby" Chinese bass scale changing to a sound something like the best of the old American pianos, and power (dynamics) improving greatly. But also the new strings were from a high quality custom maker, whereas the Chinese strings are who-knows-what sort of quality.

I should have mentioned in my earlier post that I agree with Keith about stock low single strings on a Sty M sounding like "Screen door springs".

Overall, I like the first piano better than the second. Musically speaking that is.
Kieth, can you give us some information on the ages of the pianos and a description of the work of each?

Both need tuning and much tone regulating. Judging by the way you played the same note three times, I suspect there is a difference in the way you play each piano. But let's assume there isn't. Although, because I am continually listening to fine pianists, I find that banging out notes in this manner is, to me, the equivalent of listening to a trombone player or violinist taking their 4th or 5th lesson. The piano is one of the few instruments anybody can walk up and do this to.
The second piano has glaring tonal flaws above the break that just might be insurmountable and, although it sounds "very nice," there is a distinct loss of potential power below the break. How does it balance with the treble? How complete is the dynamic range? The real sonoriy of a piano never comes across on any recording but the basic problems in each piano Are readily apparent here.
I used to prep NY Steinways by the truckload(literally) in the days before they lacquered th hammers in the factory. The M was my least favourite but could be made to sound completely different from your example with no loss of dynamic range available to the pianist.
If you are genuinely asking us to decide, the least you can do is to tune and tone regulate each piano to its full potential or to the best of your ability. I feel vaguely insulted that you asked us to "decide" without at least attempting this.
If you are trying to make a point, your bias shows and amply demonstrates a few of the problems with many, perhaps most 'improved' rebuilds.

Now that everybody has attracted my attention to the tuning, I had to listen once again.
I tried to listen with "organic and musical" ears as opposed to "scientific" ears.
To me, the second piano sounds way better.
I have good speakers and microphones, I know about recording pianos.
Given the limitations of the medium that we use to communicate, the nature of the piano, it is impossible to really tell how good the modifications are.
But, I applaud people, musicians and techs that have the courage to do so.
I still think the second piano sounds better, and I don't feel insulted having been asked.

OK, just a bit more background. First of all, as stated in the original post this is about the low bass -- not upper bass or midrange or treble. Some people who have heard the piano notice a "night and day" difference between the two adjacent pianos. I thought I'd put up a recording to get additional response. So, please keep the discussion oriented primarily to your assessment of the lowest bass octave Recording comments: First of all, yes, both pianos are not perfectly in tune. For single-string unisons, do people think a few cents matters in this assessment? There is an audible false beat on note #4-C on piano #1. All the tuning in the world won't make that go away. The first piano is new NY S&S "M" -- meaning it has never been sold. I'm not sure how long it has been on the sales floor. I don't know what the dealer does in the way of prep. It seemed rather little, but all the prep in the world isn't going to make the low bass issue go away. The second piano is a refurbished "M" from the 1910-20 era. Microphone is a USB Blue Yeti going directly into Garage Band on a Macbook. Better than the built-in notebook microphone but a number of folk here have better equipment. Garage Band is adequate to the purpose. Recording session was impromptu at the music dealer's during their open hours when I walked in and had a bit of time to make the recording without conflicting with customers. No time for tuning. Both were judged about equally out of tune and with voicing glitches. The second piano will receive thorough going over after having received 20-30 hours of playing (which the dealer gets from adjacent music conservatory). In any event, the focus is on the lowest bass notes where a few cents plus or minus shouldn't affect ability to judge an order-of-magnitude difference. The tonal deficiencies of the low bass in the S&S M are well-known and pervasive through production of that model due to design deficiencies. I didn't think there would be any challenge on that point. At the venue in question, the "M" bass was inferior the other grands of the same size including lesser instruments like Boston and Young Chang of similar size. My attempt was to make as "honest" a recording as possible in the amount of time I had. The display in Garage Band shows similar amplitude for the tracks from both pianos. Microphone placement was either equidistant from both or identically located on each piano -- depending on the particular pair of tracks. All track pairs had identical microphone placements.

It's a new unsold piano sitting on the sales floor. Excerpt from Keith's last post below.
"The first piano is new NY S&S "M" -- meaning it has never been sold. I'm not sure how long it has been on the sales floor. I don't know what the dealer does in the way of prep.

At this point I'm still looking for the answers to a question -- actually two questions. 1) Can you hear a difference between piano #1 and piano #2? 2) Which do you prefer? 3) Ok, perhaps a third, If you detect a tonal difference between the two, is it very subtle and hard to detect or is it a significant, obvious difference?
This is not intended as a trick question or test. In our line of work opinions and theories lose their relevance (or not) by what difference they actually make to what we hear and feel. At this point, let's not get lost in what may be the technical differences between the pianos. After I get more responses about what people are hearing, the details will be fully described.

I want to remind people that this is not about the tuning, hammer selection or other things! It's about the low bass. People are commenting on almost everything but the bass tone. Please stick to kpembrook's original question!
1) Yes, I can hear a difference between the pianos.
2) I prefer piano #2, it's considerably better in my opinion.
3) I think the difference is a significant, easily detected difference.

Same here for all the questions. The 2nd one is much nicer sounding in the low bass IMO.
