Thanks for the note Adam. Myself and the beta-testers did consider scenarios such as this. Surely you know we would try our best to keep the identity of the tracks hidden as best we could without invalidating the test altogether - fine line there but I think we did a good job... Therefore, indeed, it is possible for the null test to show "unexpected" results but that depends alot on other factors. Great to see the responses so far! Just with the FTP site, >120 transfers of the file already. I of course do not expect that many responses yet since there's plenty of time to listen, but I am impressed by the quality of responses so far and the variety of gear people are using! Clearly folks are not using "junk" gear to assess and the majority are spending time listing out for me what they use and subjective impressions. All will be revealed in time of course... Keep the responses coming!
