I know the A1400-8 is a definite improvement over the entry-level Onkyo I was running (thanks to current-limiting), but it's nice to hear there's a tangible difference between higher-end receivers like the 3808 and it. It would still be nice if a more proper, scientific listening test were to occur with several of the models that have been in discussion lately, including the two units PeterChenoweth trialed along with the 3808 and the A1400-8. Maybe the differences are all inaudible between competently designed units operating within their limits, but it may be surprising just where those limits are for each unit.
