Let me clarify the 'current' needs of the DA-1.1 etc. First they have a very stable curve @ 6ohms with a brief dip to a little over 4ohms @ 150hz and below that a rise to about 10ohms. As speakers go this is very smooth and easy for most amps to handle. I've found that amplifiers with much less than 30amps don't give the dynamics that these speakers can produce, but more is not always better. Depending on the amp 60 amps may not sound any better than 100amps, there are just too many factors.
