Hi rharv, thanks for the comments. This complies with my readings. Apparently there are noise issues with the base station, but it's not clear if this is a common problem or a real problem (some complaints are with a noise level of 90db...)
The bleeding is towards the monitoring, if this is also the case with the input, than this is more severe (i though there was only an issue when using multiple monitoring pairs and shutting some off...)
The issue with the preamp is new to me, again surprised since they speak so highly of the onox preamps.
I must admit, it doesn't surprise me that there are a few issues, how else could you explain the price drop of +/- 60 %
So, cheap... but not a bargain ?
