*chuckle* Max hasn't been updated since 2009, but from the bottom of the sbooth main page says "Copyright © 2006 - 20011 Stephen F. Booth. Design by Andreas Viklund." Clearly, he's more far in the future than any of us.
I have never used DBPowerAmp, but I have to wonder, does it handle RePlayGain as well as Foobar? One of FB2K's real strengths is RPG processing. When I used to use it to convert lossless to lossy, I'd RPG the the audio first. That meant I'd never get any nasty volume surprises in the iPod, and I didn't have to contend with Apple's useless auto volume function.
