Design Question

Hi,

What is the deal with these tower-like floor-standing amps?
Is it only a matter of design or function, I mean are they too heave to be put on shelves or are there any other special advantges?
As they are pretty cool I'm thinking of buiding two monoblocks
( they always come in monoblock versions, don't they?).
This approach seems good also because you can fit alot of power toroids and caps in them.

Best Regards,
Christian
