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. 🤨
