The weird thing with Toslink is that the standard is old, but the problems seem rather new. The cheap generic dacs do the job mostly fine, while the fancy news ones are hiccupingOne would think after 40 years, connecting 2 devices with a TOSLINK cable would be as problem free as using an electrical extension cord.
Same with connecting two USB-C devices together, although obviously much less mature.

What you mean has nothing to do with the ESS, AKM or other DAC chips, but was due to the AK4118 receiver chip that was mostly used in the past. This chip is extremely good and there is no alternative. AKM was not the market leader in this area for nothing.This is true. DACs built with AKM chipsets typically did not display issues with TV's and Toslink. However, after the AKM fire some new ESS based DACs started showing dropouts with TV/Toslink connections. It's a learning curve for new designs and it demonstrates how all TV configurations were not tested before release. You would think by now Topping would have a red flag out for this specific testing configuration as it showed up in the D90SE as well.
This is nonsesne, I have a bunch of plastic ones of various lengths and they all play 24/96 files without errors, and most of them actually play 24/192 as well. Sure, a glass one might be "better" espcially at longer lengths, but if your DAC is decent re reclocking the Toslink input it won't care.
It's really interesting that in this and other threads, the root problem is completely ignored.
Is it too inconvenient that the TV manufacturers (and also newer players of all kinds) cause the problem because they don't adhere to the SPDIF standard?
I have a Sony DSC-88 here, no, not a camera but a "Digital Signal Checker". The comes from the Sony Professional series and for over 20 years it was the standard for repairing and checking DAT, MD and CD players as well as professional studio equipment on the digital side.
In my circle of friends I had 2 x E30, 1 x Gustard and 2 other DACs that did not work on TVs via the optical connection.
On the DSC-88 all DACs worked without any problems. I connected the DSC-88 to two of the TVs and it couldn't do anything with the signal.
With an AK4118 board that converts SPDIF/Toslink to i2s and from i2s back to SPDIF/Toslink, both the DSC-88 and the DACs on the two TVs worked.
So if someone has a Topping E70 that doesn't work on their TV, they can send it to me for testing on the Sony DSC-88.
