The sound quality is the best I've found (to my ear). And, as has been noted, the setup is straightforward. However, I found with changing to the Ketron (as well as any change in synth) required me to rebalance my repertoire. By that I mean the volumes. On my system, for example (Audigy2), the strings settings that worked with VSC DXI or with Soundfonts were way too loud through the Ketron. The instrument volumes from synth to synth seem to really differ. And, depending on the size of your collection of BIAB songs, a switch to the Ketron could lead to quite a bit of work. But worth it, in my opinion.
