At Normans Musical Instruments, we often get asked about the differences between Yamaha's popular Arius digital pianos. The YDP105 and YDP145 are both excellent choices in Yamaha's entry-to-intermediate range, but they serve different needs and budgets. Here we'll break down the key differences to help you make the right choice for your piano journey.
Sound Quality: Where the Real Difference Lies
Yamaha YDP105: The YDP105 features Yamaha's Advanced Wave Memory (AWM) Stereo Sampling technology with 64-note polyphony. While this delivers a solid, dependable piano sound perfect for beginners, it's more basic compared to its sibling. The sound is warm and pleasant, though it may feel somewhat limited to intermediate players who want more tonal depth and expression.
Yamaha YDP145: This is where the YDP145 truly shines. It features Yamaha's premium CFX Grand Piano Voice, sampled from their flagship concert grand piano. With 192-note polyphony (three times more than the YDP105), you'll never experience dropped notes, even in the most complex classical pieces. The CFX sampling includes string resonance, damper resonance and key-off simulation, creating a remarkably authentic playing experience that brings your music to life.
Speaker Power and Sound Projection
The YDP105 comes with 2 x 6W speakers, which are adequate for practice in smaller rooms. The YDP145 steps up with 2 x 8W speakers, delivering fuller sound that can comfortably fill medium-sized rooms without distortion at higher volumes. If you plan to play for family gatherings or in larger spaces, the YDP145's superior speaker system makes a noticeable difference.
Connectivity and Modern Features
Both pianos offer USB to Host connectivity and dual headphone jacks, as well as compatibility with Yamaha's Smart Pianist app. This app provides interactive features like chord recognition, sheet music display and additional sound customisation options - perfect for modern learners who enjoy tech-enhanced practice.
Design and Build
Both pianos share Yamaha's elegant cabinet design that mimics a traditional upright piano. The YDP105 is available in black or dark rosewood finishes and weighs 37.5kg, while the YDP145 offers an additional white finish option and weighs slightly more at 38kg.
