OPA627BP is now the Standard Opamp in the MICRO

I have decided to offer the OPA627BP as the standard opamps in the MICRO amplifier.  These are currently my favorite opamps for the MICRO and bring the performance of the MICRO to a higher level than the previous standard OPA627AUs that I had been using.  My goal has always been to build the best portable headphone amplifier and I think this is it, the Portaphile MICRO with OPA627BPs.

For a pretty accurate review of the OPA627BP opamps that mirrors my findings and compares it with some other opamps, please visit this page: http://www.rock-grotto.co.uk/opamp.htm
