I haven't personally heard the Micro Portable but the DAC is supposed to be at least on par with the 06 Micro DAC and the Amp section is somewhere between the 06 Micro with the Desktop module and the Home module. It's actually the same electronics as the home module but since it's battery powered it's not as high current as the Non-portable home module units. SQ wise the DAC and Amp circuitry average out to be about the same as an '06 micro stack. Which remarkably also retailed for $600. Although I haven't heard the portable I have heard/owned the 07 Ultra Micro and the 07 Micro Stack. Other opinions floating around are that aside from the mobile series. None of the HR amps are completely night and day differences as far as SQ goes. Everything increasing incrementally is a very incremental increase in SQ. I'm sure that if you got the Micro portable with the DAC you wouldn't be disappointed. Plus there's always the 30-day return policy.
