I still think it was jack relate , maybe one of my new Roland jacks was breaking something , one did seem to be rather sharp and pointy , but haven’t checked to see it is a standard length.

The UMC1820 processes input signals through the studio-grade 24-bit/96kHz converter to deliver premium sound quality.

The SPDIF /ADAT button on the 1820 headphone area seems to be for listening to incoming and not the SPDIF output. Both units FR18i20 and the Beh1820 supposedly handle up to 250ohm headphones, both offer SPDIF 2channl outs to connect my Grace Design Headphone Amp to work and it handles anything.

However the left front jack was making a horrible digital interference noice , I removed any usb connections , still there.Tracktion is one of the world's fastest and easiest Digital Audio Workstations (DAW) for composing, recording, editing, mixing and sharing your music with the world.

Thanks for the reply, it wasn't glaringly obvious to start with but after a few sound test decided something sounded a bit odd like a phase issue so tested it by connecting a pair of mics one to each unit and recorded a pop simultaneously onto two mono channels then zoomed in on the start of the waveform and immediately could see they were well out of phase, the measurement between the start of the two recorded waveforms was 40 samples.When it's time to make recording history on your Mac or Windows computer, plug in microphones, instruments or line level sources to the UMC1820's 8 combination XLR / TRS inputs for the ultimate in studio flexibility! For a whole project I just ran everything in and out of the UMC1820 and the end result was just as good as the projects I recorded using my Apogee gear. then I tried the SPDIF out because my GraceDesign Headphone DAC outboard amp, it needs a SPDIF IN RCA connector.
