Dears.
Just this weekend I have tried a Transparent Opusisolator on my system. First tested Phono Amp D'Agstino Momentum with Opusisolator, the result was just amazing. Exactly the same as already described by jfrech. But when I tested with EMT-927 with EMT-139ST Phono Amp, the result was very poor. Also tested with Phono Amp Allnic H-5000 and Line Pre Amp Allnic L-8000 and the benefit was also outstanding (same case as with Momentum) Now, I can't live without Transparent Opusisolator. The richness is simply amazing never experienced on my system. But as I have too many gears, I will need 4 Opusisolator extra and this is insane due to cost. Anyone have compared Opusisolator against another filter like Audioquest Niagara 7000? I have tested many filters on my system but never got a good result. Before Transparent Opusisolator, I have used only Hydra for digital sources, but now I'm really interested to add filters to my system.
