How to physically move large heavy 100lb amplifiers easily (up and downstairs)


Ideally with only one person, but even with 2 especially if there are stairs involved, how can I move this gear without breaking my back or hurting myself?

Wait....go back to Erik’s post.
can I get speaker cables long enough to reach the hifi dealer in Red Bank?
then I can ask him to connect my speakers to different amps every other day.
I have B&W 803 D speakers, purchased 15 years ago.  The dealer had two men deliver them to my upstairs listening room.  At the time I was in my mid 40s and in great physical shape.  I want to replace the speakers but since the I have had heart and back surgery and no way am I shlepping these downstairs for a dealer to demo in trade in.  I bought a 90 pound amp a few years ago and that will reside in my system as well until I move
