Hi, new forum member here.
First, the Preen FM2 is fantastic, thank you Xavier and everyone else who keeps developing new features.
However I think I made a mistake, I jumped in and bought a pre-built SMD version without being aware of the differences. I have linked a recording of a single sine wave, 1 voice, with no modulation and all other operators off. There is a noticeable 'phaser' sound especially as it fades out, that I don't think should be there with pure sine wave (other synths sine waves don't have this sound).

Is this normal for the PreenFM2? Is this maybe a problem inherent in the SMD build and specifically the use of a single audio output jack? I don't think it is aliasing as the digital processing should be the same?
The general functioning of the unit in terms of MIDI control and parameter settings all seems to be good.
Am I just being overly sensitive about the sound?
Many thanks
