Bitstream DAC won't lock onto CEC transport

The Bitstream DAC will not lock onto my CEC TL-2X transport. It will lock onto my 15 year old Sony 10 disc CDP though (yeah even back then Sony made it with an RCA digital output). I tried five different cables and every time the Bitstream locks onto the Sony but not onto the CEC.

I also tried plugging, unplugging, etc., etc., etc.

Any help is appreciated.

Did you call John Wright? He may be able to help.
BTW you have a fantastic dac. Hope you find the problem.
Yes and he said the DAC should lock on with no problem. Someone told me that a few CEC owners had a problem with the transport and they needed a true 75Ohm cable, the CEC locks onto my AUdio Logic DAC no problem. I am stumped.
Hey, send ME the Bitstream, if it locks onto my CEC there might be a problem (doubt it) with yours.
However, if it locks onto mine, I might NOT want to unlock it ever again, esp. if it sounds decidedly better than our Audio Logics, then I'll be stumped !!!
Sell the CEC. Junkkk.
I had both the Bitstream and IDAT on hand some time ago. Using my Sony DVP-S7000 as a transport I had some problems locking the signal in when using the Bitstream but not the IDAT-44. Doesn't really answer your question but maybe the Bitsream is more tempremental to the transport???
does the bitstream dac have other inputs,i have a cec transport and i use the balanced output,can you hook it up that way.
The only option is toslink and the CEC only offers ST-optical so no luck.
