It just goes to show how much variance there is in the way people work 
and use Ardour.

I've never accidentally set up a feedback loop. I have had loads of 
issues over the years with plugins spiking. I'm starting to use a more 
limited set of plugins now and it's also one of the reasons I finally 
went down the payware route.

I think the spikes I had recently in A3 were around the 50 dB mark 
(caused by a free one, but I can't remember what it was). But even that 
can be very painful, especially on phones. But the 600+ dB spikes I've 
had on A2 in the past take some beating. That's something I'd like to 
see stopped, I don't need saving from myself :-)
