No test.
i had time to test parasound dac 1500 in sound dynamic better than opa 845 627 is a good upgrade
Fast - 16 days. The version is OP01, not the one announced - OP03. The idea is good, but the stunt ... The sound is weak and timidly poor. Bad components or otherwise ... I tried it as a buffer after a DAC - all the OP-AMPs, that I have available, play better.
