Simple, small and practical - but unfortunately growing latencies

The small Übersetzerlein between SPDIF optical (Toslink or F05) and copper (RCA) is installed very compact and fast. Not to be confused, not misleading - there are only three connectors: TOSlink + RCA + power. Fully wired, it has the shape of a T-piece that fits with normal depth still well behind the hi-fi system.
In addition to the great rates, this are its good points.

For longer runs it is striking that the converter with the time increasing in latency - the images on the TV run the (converted) sound more and more forward. Only dragging and re-insert the power plug on the converter returns the Lippensynchronizität. If we make this the built-in TV speakers on, you can hear clearly that the delay is not caused in television, but in the converter.

Multiple channel change and related changes of sound standards (normal Stereo vs. Dolby Surround etc.) also causes sometimes that the transducer remains simply dumb. Here helps only off and on again - but reliable.

Rating: Not inexpensive - but not without quirks.
