Get the cheapest lightest amp you like the sound of. :)

You mean the sound it makes when it hits the ground?

While your question was poked fun at by some, this exact question came up for a friend and I yesterday. Why? Because weight is touted as a "pro" for some amps and we didn't know why. Your question elicited some good reasons.
I reckon you guys ain’t heard of the ultra-low mass amp craze that’s sweeping the nation. I use an ultra-low mass portable CD player with headphones. Total mass less than two pounds. No big honking transformer, or big honking capacitors, monster power supply, no big old power cord, no fuses, no interconnects or big honking speaker cables. Or their attendant noise and distortion. No more pencils, no more books, no more teacher’s dirty looks. 🤨
