Hey! The pics gotta be there somewhere!! Or maybe I forgot to paste... but that cant be possible, I'm not THAT dumb!

Meet was good, I came super late though, so I guess I missed everyone 'cept Helter Skelter and Born2B. Brought along some of my gear but peeps were winding down so we ended up watching Family Guy on Helter SKelter's laptop instead.

Coming from you, ppl, that means alot to me! This competely reaffirms me of my Micro DAC purchase. I didn't get the Micro Amp though, so I'll definitely have to consider something like a PPA eventually!

Yeah, I think cost is somewhere in the neighborhood of $900.

This Device Larry never got any Interest in so it is not part of LaRocco Audio's Line. this Amp was built for my needs by me and was being offered by larry as the Globial reference however since not one person ever asked about it and only one was ever sold making mine one of two ever made. this amp is uniquly set up with trappings not normaly included in most all other PPA's like On board Voltage regulation made from Discrete components as opposed to IC's. Three posistion Power For (1) Amp and DAC (2) Power off (3)Amp only This way the Amp alone consumes about 70 mA no load and 160 mA with the amp and DAC going at once. the DAC's current consumption is somwhat dependent upon Bitrate. this ampalso includes a 900 MAh AAA battery Board as showen on tangents PPA battery board site http://www.tangentsoft.net/audio/ppa/bb/
thePPA is my Moded V2 that includes different component values in the output buffers of the PPA and AD744 Op-Amps operated from the compensation pin for best transparrency and not requiring the J-FET Op-Amp Class A Bias components thus extending battery live while enjoying sound supiour to a conventionaly Class a biased opamp the DAC also uses the AD829 in the same comp pin method for some real fast and low distortion DAC analog stage.
