A problem you run across occasionally ... a superjumbo that's too quiet.
I seem to remember Lexus having a similar criticism leveled at them a while back.
Is there a piece of equipment etc. in your possession that is executed so lavishly that it actually becomes a drawback?
(An example: as a woodworker I am aware of a chisel company that polishes its premium chisels so highly (and in doing so rounds off the sharp corners) that a lot of woodworkers opt for their basic model instead - they find it an easier chisel to 'tune up' for use.)
