I had a LPS-1 before the LPS-1.2 it failed the same as yours, in about 1.5 years.
the 1.2 was sent as replacement for the first one.
There was zero improvement in Audio sound.
I know better to believe there would be but this is a hobby to waste money to vendors that sell toys that do nothing.
There is a video on Youtube that shows adding a LPS to a opticalRendu.
This is utter nonsense. The entire chain is digital
and not affected by the silly idea of noise.
It Is irritating to see UpTone continuing to sell junk to unsuspecting buyers.
