Hey Rob, Ease dropping.... I used to work for a Samick dealer and now still run into lots of Korean pianos in the field. Your experiences are typical in my experience. The pianos just are not stable. If the piano is left in the field unchecked it will get so bad that removal of all dampers and complete action easing is often necessary. Under levers, guide rail, flanges, jacks, balance rail holes, key bushings....all of it. Steinway and other makers lean the damper wire to one side, the problem here is that the bushing is just too tight. Ideally, ironing the bushings with a bridge pin in a electric key easing tool (with thermostat) permanently fixes the bushings, also key ease the bushings. I use the chuck side of a drill bit to size the balance rail holes (mic to size slightly larger than pins) and use methanol and a hair drier on the rest. If the these pianos are received and kept dry these problems are minimized, but they are usually allowed to swell up and you have these problems. You may also have action noise, string voicing problems, damper seating problems, and false beats. When I see one in the field for the first time I always recommend a Dampp-Chaser.

I work at a Baldwin dealership, and lately it seems that I've been having a lot of problems with new Wurlitzer (Samick) grands. Two specific problem areas: 1) sluggish jack centres that result in a non-returning jack, but only after about a half-hour of continous playing. I replace the offending pins, which are invariably tight in the flange and loose in the birdseye. Not easy to spot during floor prep - do you experience this and have appropriate early detection remedies? and 2) @#$%@#$% dampers that hang up into space. Again, they usually manifest themselves once in the field. They are usually just brushing one side of the guide rail bushing, and a gentle wire bend accompianied with guide rail bushing reaming cures it. However, any preventatitive preparation techniques would be appreciated. Happy non-denominational winter festivities.
