Grand piano brands vary in scale construction, materials, and manufacturing philosophy, but on the used market the single biggest value driver within any brand is still condition and maintenance history, not the badge alone.
What genuinely differs between manufacturers
- Scale design: how string length, tension and soundboard size are engineered together - this shapes a brand's characteristic tone more than any single component.
- Action parts and touch: manufacturers differ in how the key action is weighted and regulated at the factory, which affects how a piano feels under the fingers before any technician adjustment.
- Parts availability and service network: a well-established brand with a strong technician network locally makes future maintenance easier and cheaper than an obscure or discontinued make.
- Manufacturing era: even within one brand, quality and specification can shift meaningfully between decades due to changes in ownership, factory location, or materials sourcing.
Rather than ranking brands in the abstract, it's more useful to research a specific model and production era, and to weigh that against the condition and price of the actual instrument in front of you.
