The rack I used on our last gig is small and simple but mighty and toneful:
"small", right?
Anyways, apart from The kind of power amp like Jim is using, I have yet to hear a rack power amps that can deliver the same punch and dynamics as a 100W top with properly dimensioned transformers (I am talking 2U sized power amps which all have "smaller" iron in them).
I used to own a VHT2/50/2 and while it was pretty nice, it disappeared and sounded small compared to my heads with the big iron (Bogner Shiva / XTC, the Steavens Poundcake or the Cornford Mk50).
Obviously those monster power amps like VHT2150, Rivera TBR ... they have transformers like a head, which makes them sound the same I guess.
Other than that I don't believe there is a big difference. Especially as soon as you use the loop of an amp, you lose the kind of signal integrity that makes a head sound THAT unique.
