Are Blüthner Pianos Good?
Yes, very. Blüthner is one of the handful of makers spoken of at the very top, alongside Steinway and Bösendorfer, hand-building pianos in Leipzig since 1853.
What people love about them
The warm, singing, romantic tone, softened in the treble by the famous aliquot string, and the hand-built quality of a top-tier German maker. Composers and concert pianists have prized them for generations.
The honest picture
Blüthners are expensive, and for a home a great deal of that quality is more than most players will use. They are also less common in the UK than Steinway or Yamaha, so choice on the used market is limited. Neither is a mark against the piano; both are facts to weigh.
