I've finally put my HA-1 review up. I didn't go through every aspect of it. Admittedly (aside from moderating this thread), I purposefully stopped reading after the first 20 pages and did my review without getting any subtle/subliminal "influences" from other posters here. Overall I think it's actually very good value for money. If I had only $1200 to spend on a desktop DAC/Amp, this would be it - probably even over the HP-A8 which I had owned for 9 months. However between the HA-1 & my current Invicta v1.0, I would say I'd still lean towards the Invicta. Is it worth 2.5x more than than the HA-1? Probably not but as expected the Invicta is more involving & more spacious, than the HA-1. I must say for a $1200 DAC/Amp it's hard to fault it.
