Hi.
Just because I searched so hard and couldn't find a good verbal comparison, I thought I would post one here for interest sake. I am not a professional pianist and play at roughly grade 7/8 Trinity College level currently. I have heard a professional pianist play and comment on these pianos as well. His comments matched my impressions.
For information, the price is relative. These high end pianos are very rare in South Africa, so more expensive than elsewhere in the world. No dealer I spoke to has even seen a Bosendorfer upright. Steinways are more common.
My Bosendorfer has now been regulated and tuned.
The pianos:
1982 Bosendorfer 130CL upright. Unplayed in 33 years and last tuned on delivery in 1983, so basically new. I paid +/- $12 000
1917-ish Steinway K upright. Pretty old but in good condition, it may have been refurbished a few decades ago. Value about $8 000.
The touch (Both have ivory keys):
Bosendorfer: Quite a bit heavy and stiff, being new. But it is really superbly accurate. The range of dynamics you can get out of a note is impressive from ppp to FFF. It makes you want to play over and over so you can try the different sounds. Trills are very even. The touch is so accurate that you can hear every single variation. I used to think I was ok with scales, but now I can hear how uneven they are. I enjoy seeing just how soft I can make a note. Its amazing how I can feel what the action is doing on my fingertips. Wonderful tactile feedback.
Steinway: Very very light touch. A real pleasure to play lightly. I have to work harder to get a stronger sound out of the piano and struggle a little to vary the sound by small amounts when playing FF-FFF. The lightness makes speedy runs a breeze. The touch is also very accurate, but not as much as the Bosey. The Steinway is more forgiving. Like the Bosey I also get an excellent tactile feedback from the action
The Sound.
Bosendorfer: It is, once again, superbly accurate. Every sound is crystal clear, sharp and pure. The trebles are extremely crisp and pure. The bass is not overwhelming, but very solid and strong. The tenor range has a very distinct woody sound. Once you hear this its evident, for instance, in Schiff's recordings of Schubert on a Bosendorfer grand. It takes a little getting used to, but its just a different sound. Its so warm and pleasant. I really like the sound. It is very even from bass to treble. My friend played Haydn sonatas which was just sublime. Same goes for Bach. I find the Bosendorfer has a great ability to fill a room with sound. A very solid sound, but you can pick out the specific notes due to the accuracy. I understand when all the online blurbs say it sounds like a grand. Not quite, but there are parallels. The "Una Corda" on the Bosey is much more evident than the Steinway. It makes the notes very clearly softer.
Steinway: Where the Bosendorfer is accurate, the Steinway is colourful. Impressions are that it has a very powerful bass and very bright treble. I find the balance a bit uneven. The trebles can jump out and the bass can be overwhelming. That said, I am also inspired to be more romantic on the Steinway. to let the sounds linger a little more. Its more velvety. I think I struggle a bit with the softest sounds to get it even. But this may be my own technique/skill limitation and not the piano's fault. It doesn't fill a room as well as the Bosey. Its like the sound is more focused at the piano?
Conclusion:
I like both pianos a lot. I think the Bosendorfer can be superbly rewarding when played well. Its a joy to play and experience. The Steinway is very interesting to listen to. It is a different sound. I feel more serious when I play on it. I think the Bosendorfer is better as a performance instrument when playing for others, the Steinway perhaps more personal. My friends comment that the Bosey has a beautiful sound when they are around the house when I play, but on the Steinway they comment on the music itself, not the piano. I think the Steinway sound lends it a bit more to romanticism. The Bosendorfer is definitely nicer to listen to with the Haydn and Bach I heard. But I play a Mendelssohn song without words on the Bosendorfer that sounds sublime too and its improving. I just need to learn the touch more. So this opinion could change.
Either piano is a great piano and I don't think you can go wrong with any of these.
I am very very happy with the Bosendorfer, but had I not found one, the Steinway would have been completely satisfying.
Now I am hoping the work day can finish so I can go listen to the Bosendorfer again.
I hope this is helpful to some people.
