This is a disappointing read.

Is this another case, similar to the 218, of M skimping on the PSU.

I’ve noticed recently the brightness and colour saturation on my TV has diminished. Is this an indication of PSU voltage drift?

I inserted the HD621 in the chain in the expectation that it would tidy up, if not improve, the sound and vision signals.

Has there been any experimentation of utilising an external LPSU as per the 218 thread?

Is the same PSU used in the UHD722?
