I have heard the all TAD system at Pioneer Plaza in Japan, at their TAD showroom. Was shown around by one of their senior execs who happened to be there...a true gentleman. I was very very impressed...on Glenn Gould, I appreciated the clarity of the fingerwork by Glenn Gould...but found the tonal weight of the piano keyboard particularly in the middle a bit hard/light. Simply my opinion...and who knows...maybe it was recorded that way. But I have heard this recording for years and years and on multiple systems. And with the ones I preferred, the tonal balance and weight of the keyboard sounds much more like when I used to study piano. Nevertheless, I fully appreciate the appeal...and think it might be that the whole system could be setup more to my personal taste with a few different components rather than a necessarily deficient design or system. I don't think it would take much. in the end, I admit it did not compel me to investigate further. YMMV.
