Perhaps a single short custom made extension cord? or, send your amp to CJ to get the cord lengthened? or have a tech install an IEC into the chassis? (Furutech makes a nice gold one for $20 FI-10)
The simplist would be to just make a cord yourself with the added length you need. Use plugs from a hardware store, and have a single female A/C on the end. Then it will look a lot better than an ugly powerstrip sitting there. Use a big cord like ten gauge 3 wire cord in your short custom extensioncord. I made one like that a few years ago. and just keep it around. Mine is like two feet long.
