I sell CEC transports because it is the only transport I ever heard that does not "guess" at what the music is supposed to be. There is no jitter in a CEC transport. The noise level in the signal sets the standard all others try to match. Many of the transports you can buy are actually made by CEC, if it comes out of Japan. CEC products are just the house brand.
The CEC products mentioned here are previous models and not current production. I have customers who will not give up their 20 year old transport and just want to get it fixed when it has an issue.
