By now anyone interested in testing this hybrid piano, with its acoustic upright touch, knows the specs, as they're all over the internet. And according to World Piano News, the Japanese price translated into USA money is $6,200. This isn't to say it will sell for that much when the piano is released to the States, but that's in keeping with what I believe will probably be a $6,500 price tag, with dealer discounts applied.
It appears to me that there's nothing really new here, as compared to the CA98, save for two things: the keyboard action and the damper pedal. In polished ebony they're both beautiful instruments and have the exact same tones. Speaker volume, for a home setting at least, isn't worth thinking about since there is no doubt they can both be very loud.
Obviously consideration for the NV5 centers around the action, and a person might think that an actual acoustic upright touch would be far more desirable than a digital grand feel, but I'm not entirely convinced, just yet anyway. For anyone thinking of buying either of these instruments, trying to gauge the short term and long term comfort of playing on either might be a trial. My feeling right now is that investing in the acoustic upright action possibly might be the smartest move; it demands more hand strength, but also strengthens the hands in the long run. But that's just my thinking. There are far better opinions on this subject than mine, and I'd certainly like to gain everyone's input.
