Anything SS sounds better than D'Agostino ?

How, on earth, you can judge the sound on youtube?  D'Agostino amps are very good (according to reviews), but extremely expensive.  Better question (for most of us) would be "What sounds best for the $"

@inna you mean you judge the sound of world best amplifiers by using youtube? Your tube sound is recorded in unknown space with unknown speakers by unknown microphones, by unknown recording engineer to create 128 kbps AAC? You must be kidding.

George, I don’t know Antillion amps and I’m sure they are great, but 7500W into 0.25ohms requires 173 amperes? What kind of power supply can deliver 173 amperes? What about size of conductors? Most of the current will go to woofers, but there is a choke there that has on average 0.1ohm. Power dissipated at this choke would be close to 3000 watts. This choke would evaporate. Perhaps we are talking about average power ( sinewave typical for bass frequencies). This average power would be half of peak power equal to 3750W. It will result in 122 amperes and woofer choke will get close to 1500 watts and will still evaporate instantly. What am I missing?
