thanks for clarifications then the probability of actual hires recordings would rise , some existing ones may have those qualities even if the producer did not have those intentions . Sometimes they just wanted to make a good sounding record :) . Then maybe some suitable test tracks could be available if there are >=24/96 originals left. If they at least actually have intrisinic sound quality far above CD quality , again the audiability may or may not be there but the technical quality could be . That would fit archimagos purpose for a fair blind test , the test track must have qualities beyond CD quality so that a meaningful comparison with a downsampled version could be done . Otherwise the two version would be "the same" practically . I do think some AIX stuff fits the bill they sound very good . Possibly 2L have some tracks too or Linn -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
