I've spent some time with various Yamaha Portable Grand models, and I can definitely share my experiences with you. Sound quality is one of the standout features for these keyboards. Yamaha has a strong reputation for creating realistic sound samples, which holds true for the Portable Grand series. While they may not fully rival a full-sized digital piano with expansive speaker systems, they do a commendable job of bringing a rich and resonant piano sound to a more compact form.
In terms of playability and key sensitivity, it depends on the specific model you choose. Some models, like the Yamaha DGX-660, offer graded hammer action keys. This means they mimic the feel of an acoustic piano, with heavier weighting in the lower register and lighter weighting in the upper register. This can really enhance the playing experience, especially if you're using it for practice and want to maintain the feel of a traditional piano.
For portability and small gigs, Yamaha Portable Grands are a great choice. They're relatively lightweight while still offering good build quality. I’ve taken mine to several small venues, and it holds up well. The onboard speaker system is sufficient for intimate settings, but for larger spaces, you might want to plug into an external amplifier or PA system.
When it comes to getting the best value, the DGX-670 is a model to consider. It offers a great balance between price, features, and quality. You get a slightly upgraded sound engine compared to earlier models and better connectivity options, which are handy for integrating with other gear.
Something to keep in mind is that while these keyboards are excellent for their category, if you’re used to a high-end digital piano, there might be some noticeable differences in response and sound projection. However, for many musicians, the trade-off in portability is worth it.
If you're interested, Yamaha's website often has detailed specifications and audio demos that might help further with your decision. I'd also recommend checking out review videos online to see the instruments in action.
Do you have any specific requirements or gig scenarios in mind? That might narrow down the choice a bit further!
