As for CEC, its under consideration I’m just worried about belts. The reason I’m looking for a top loader is its one thing less to worry about.
FWIW, the main reason that I replaced my (excellent) SimAudio Moon 260D transport (not a top-loader) with a C.E.C. was not the belt drive, but the use of a weight employed on top of the CD. Electrocompaniet used the same basic approach, as do some other manufacturers, and I am fairly convinced that there are advantages.
As for the belts in the C.E.C. products, my understanding is that at least on the newer TL-5, which I own, they are very easy for the user to replace, should it become necessary. No need to send it in for service.
