Question: Why is there such a difference in price between the different model numbers?
As with all manufactured goods, the more you pay for a product generally reflects the overall quality. In the case of acoustic pianos, this can mean where it was built, the size of the cabinet – which also refers to the length of the string and therefore the quality and tone of the piano’s sound – the materials used for each part of the piano, and many other factors. In general, you pay more for pianos built in countries like Germany or Japan than China or Indonesia, as this can reflect the quality of the manufacture, right down to the attention to detail paid to the placing and fine tuning of action parts or even the hand-finishing of the wooden cabinet.
With digital pianos, the price is much more likely to reflect the number of features available and the quality of three main factors; the action, the piano sound, and the amplification used to reproduce that sound. For example, while many basic digital pianos will have a handful of voices, a metronome, small lower-quality speakers and a less responsive or realistic action, as you go up any manufacturer’s range you will find a much bigger selection of voices – along with effects and ways to control how each voice sounds – along with extra features such as recording functions, accompaniments, increased connectivity options, high quality speakers and a more realistic action, often with wooden keys.
