Sorry, I misunderstood your ref to Ian's DSP tweaking.

If he wanted to 'improve' the EP400 DSP Software (for all following 400s in that model line) to eek out a bit more oomph at the lowest end, I wasn't going to argue with him. The only downside was that I had to wait a couple of extra weeks for delivery - something that I was more than happy to do.

Interestingly, my EP400 actually went for a ride on his 90' tower during the final testing.
