Electrolove - thanks for posting the Zimo link. Like many others here I had always discounted using Zimo products because of the price - I guess its you get what you pay for, as they always seem to have loads of features.
What I am quite excited about however is their new sound decoder - it appears to be another 16 bit processor like the Soundtraxx Tsunami. It will be really interesting to see how this matches up - maybe we will have a 16 bit diesel sounds sooner than we thought ..

I'm not using the system but I'm a long time user ofd their decoders.
All my German and US engines run the MX620 (older ones with the MX62) or MX63 if the current exceeds 800mA. They fit P2K and Atlas motors very well. They run very smooth and silent.
The firmware can be updated easy with a simple interface.
