DTS-HD MA bitstream decoder flaw can damage gear...

I don't know if anyone has seen the thread in the Blu-Ray Players section of AVS forum here, but there is a BIG issue with DTS HD-MA with the Onkyo and Yamaha (some Pioneer users have posted the same problems) receivers. Apparently the DTS decoding IC supplied to Onkyo, Pioneer and Yamaha is defective causing loud popping sounds which can and has damaged some audio gear. The popping noise is NOT affected by the receiver's volume control and has caused blown speakers. Unless the issue is resolved, it is not recommended to use bitstreaming DTS-HD MA on Onkyos.


"DTS Global Product manager Ronny Katz confirms that the problem is caused by a faulty DTS Decoder Chip (IC) in the Receivers of the companies of Onkyo and Yamaha. Recievers from Denon, Pioneer and Sony, which uses a different DTS Decoder Chip are unaffected and has no difficulties bit-streaming the DTS-HD MA tracks from the titles concerned. DTS has a made a fix/update to their Encoding software which will address the problem by taking the faulty DTS Decoder Chip into consideration, thus avoiding the issue on future Blu-Ray releases. It is however unknown at this time, if the Recievers with the faulty DTS Decoder chips can be fixed to work with the current DTS-MA discs by firmware update."
