The EWQL pianos are rather disappointing, even though there are 13 velocity layers, they are still somewhat unevenly distributed. A few digital piano geeks have tested the EWQL pianos, and have found that one of the samples for the Bechstein model has a siren in the background! It is reported that their noise floor is rather high throughout all the models. OTOH, you can tell that Quantum Leap was aiming for a studio miced piano sound, which they got, but Ivory (especially) sounds more natural, with the library more characteristic of the original pianos.
Shadowfax, I would recommend you check out the Galaxy II set. Their demos are fantastic to my ear, and their Vintage D piano is one of the most revered pianos for playability by concert pianists. Available are the Bosendorfer 290 and Steinway D that were included in Ivory as well as A German Bluthner in place of the Yamaha.
I apologize, Sherz, for getting off topic.
