I have been using a CEC TL5 for some time, and find it to be solid, and very well-designed. It sounds excellent in my system. Customer service is excellent (I swapped remotes). The fact that the belt can be replaced easily is also a big plus, in my view.
I am not typically a "skeptic" (e.g. I use good cables, etc.), but frankly have a difficult time understanding how two high-quality transports would "sound different".
