Be aware that the TU-DST51 is the defective device, not the surround processor. The Panasonic STB has occasional bit errors in its AC-3 bitstream. The Technics decoder merely masks these errors as small clicks. I usually hear them out of my center speaker, but all speakers can have these clicks.
The real solution to this problem will come from a playback machine without these sporadic AC-3 errors. Stay tuned to reports on the 169Time solution and also the Victor HM-DH30000 D-VHS deck. Reports are that audio plays back without error on these devices, and hence can be used with all AC-3 surround decoders.
