This part of the review cracked me up, in light of what Mark said earlier:
"Murphy's Law strikes again
One hundred and forty pounds is a hell of a lot of amplifier to haul around, especially when it arrives at the front door 30 minutes before I have to be at a symphony rehearsal. What makes the situation even more maddening is when the darn thing doesn't work. That's exactly what happened with the first review sample. The first thing I noticed was that both positive five-way binding posts at the left channel output were defective, and would slip upon tightening, therefore preventing a solid connection. Perhaps that's why the sound was so covered, and the amplifier soundstaged so poorly. Even after six hours of warmup time, the situation had not changed, so I called Dan at Krell, and was instructed to immediately return the unit. That evening I was admitted to the hospital, since I could not walk, sit, or stand up. Don't carry this amplifier by yourself.
About four weeks later, the second review sample arrived. This time around, I paid the air freight driver to wreck his back, so that I could listen pain-free. From the first moment after startup, I could tell that this was a beast of another color. It worked."
