I agree- those Tivolis are pretty incredible. A couple comments/additions:

1. I think those radios have non-standard, cool technology to get such a good frequency response out of a single driver
2. The real beauty of those things is their tuners; I started to raise my eyebrows at
"Well, I like to wake to talk radio - but this thing does that better than ANYTHING I've heard - including axioms!"
But then I remembered the cell-phone-like tuner in the Tivoli, compared to the standard-to-poor tuners in almost all receivers. So, I'm going to interpret that as a comment on your receiver.
