None of us listens to a tube or a transistor alone; It's the implementation, i.e. the amps, we listen to.
One good thing about tubes is that a circuit can be stabilised w/out feedback thus eliminating extra "length" in the signal path. Another is that, given the lowish output in these circuits, one can build a tremendous driving "engine" (i.e. trannies & rectification and energy storage) to accommodate those few watts.
As Eldart pointed out, tubes can easily go into the MGh region just as transistors -- they just have high output impedance to drive devices like spkrs directly (unless you parallel them & then some, see OTLs).
Likewise, a transistor amp, designed to cover a wide bandwidth should do well -- as long as it doesn't have severe phase problems (i.e., the time window for a 0,5MGh signal is much smaller -- i.e. you have to rise & fall faster in time -- than, say, a 500Hz one).
BTW, if I'm not mistaken, Mr Berning doesn't use output trannies in his basic designs...
