One weighs a ton and has a highly unrefined sound, one is light enough to pick up with one finger and has a very clean, accurate sound.

I'll let you guess which is which.....

It's called distortion. Makes things sound louder (psychoacoustics is an interesting subject). 'Warm' up the sound with some tubes (real or dsp) and you'll be there.

whatever you might wanna call it, the question still remains can it play real low sub bass as good as the crown?

OK.. I have worked quite a lot with both of these amps as well as quite a few other products in the same power range..
 
For general purpose use, the Lab wins - its light, compact and fairly powerful.
 
For bass heavy electronic music or reggae*, I'd definately go for the Ma5000.. It doesnt sound as nice as the Lab, its big and heavy, but its got a real powersupply** wich makes it able to deliver high power for extended periods..

* Tracks like these will make the FP6400 run out of steam pretty fast if you are running it at close to full power..
 
** A lot of the lightweight amps on the market today tends to have some issues with the size of their PSU - they simply cant deliver full power constantly..
 
The powersupply issue can be described using the plumbers example:
 
you need a 10 litre burst of water in 1 second to flush the toilet..
there are 2 ways to solve this:
A: Install a HUGE waterpipe ( the conventional, heavy amps like the 5000VZ )
B: Install a reservoir and connect it to the regular 1/2" pipe in the building.. Dump the contents of the reservoir when you need to flush.
 
Solution B is by far the most cost effective method, and it will work perfectly under normal conditions, but when you invite your friends over for pints, the toilet will see a larger demand for the reservoir - infact the toilet will be flushing so often that the reservoir wont have time to refill completely..
 
I had a cheapish lightweight amp on the bench for some time ago.. Specs claimed it to do 2K into a 4 ohm load.. It did, but only for less than 0.5 seconds wereafter it dec  ided to use the limiter to keep the amp in the PSU safe mode..

I don't even think the 5000 is seen as a sound (haha) investment anymore, whereas a Lab4000 / Fp6400 is..
 
And from what I've found, heard in real-world jobs, they deliver 'low bass' perfectly well.... and I mean low bass, not just dance music!
