Piano-only price
The keyboard package before optional furniture and destination costs.
It is the route's $1,000 eligibility test, not the final room total.
List stand, bench, pedal, headphones, tax and freight separately.
A bundle photo does not prove those pieces are included.
Weighted action
A mechanism adds resistance across 88 keys.
Each maker uses a different named action and geometry.
Try the exact action family on quiet repetitions and scales.
“Weighted” does not mean identical to an acoustic piano.
Slab piano
A portable keyboard body sold without a permanent cabinet.
It preserves mobility but shifts stability and pedals to accessories.
Match the exact stand and pedal model.
Any X-stand is not automatically suitable for every room/player.
Switch pedal
An included pedal usually sends simple on/off sustain.
It is not the same as a continuous or three-pedal furniture unit.
Confirm the named half-pedal-compatible accessory.
A 6.3 mm plug alone does not prove compatibility.
Polyphony
The maximum simultaneous voices the engine can maintain.
Layers and sustained passages consume voices.
Treat 192 versus 256 as capacity, not sound quality.
The biggest number does not choose the piano.
Line output
A dedicated connection to an amplifier, recorder or interface.
It avoids repurposing the headphone jack for some setups.
Check mono/stereo routing and cable type.
USB, Bluetooth and line audio are different paths.
Seller warranty
Retailers may add channel-specific coverage and returns.
Thomann and Sweetwater terms stay with their own invoices.
Save seller, serial, destination terms and packaging.
One store's three-year term does not transfer.
