Thanks gdnrbob.I agree with you that technology is constantly evolving. I'm wondering about the specifics that have allowed the miniaturization of internal power supplies in very high end preamps.
Internal Power Supply Technology Changes since 1999?
I use an older very high end preamp with a separate power supply that is the same size as the preamp itself. .
The same manufacturer now makes better preamps,without the external power supply, that are about the same size as my preamp. What have been the technology changes that have simplified and presumably improved the power supplies?
