I had an A28 last year that I bought ex demo over the counter from a local dealer. I passed it on when I got my new Creek 5350 amp but agree that the A28 is an excellent amp. When I saw the sellers description I thought it was my old one (photocopied manual and a slight indentation) but it was the wrong colour! I wouldn't worry about the power lead, mine worked perfectly fine with the bog standard lead provided (as has every other amp I have ever owned incidentally). Enjoy.
