Oh yeah. It was a 6 week listening test whereby I wore a blindfold all the time I was at home and threw blankets over all four amps so I couldn't tell which one I was plugging cables into. And you know that amp in the middle of my friends living room. He wasn't allowed to look at it for 5 days in order to make sure he couldn't hear the difference. And my pal in Florida, count him out because he's been listening and staring at his A1400-8 for six months.
