Of those appearing under the CF Stein brand, all I saw appeared to be
of above average though not fabulous quality when new... some more
above than others. But when dealing with pianos that old, issues of
condition supercede issues of brand name. If you have one in great
shape, then good for you. As far as getting into comparing the
features with Steinway, etc, just know that some care went into the
design, but in the end, it's not "special features" which makes any
piano good or poor. It's the integral of everything from design to
execution. Every piano has it's "special features", but it's really
not that meaningful a thing.
What's nice about companies like CF Stein (or today's Charles R
Walter) is that since there is not a lot of hype about the name you
can get a good deal on the instrument, even if it is of better
quality. OTOH, you will almost always pay a premium for a Steinway
even when it's a total junker, just because that name holds so much
prestige.
