Is Microphen really the same as DD-X?

    Yes? No? Maybe?

    Anyone have some insight?

    Has anyone developed Delta3200 in both and seen any difference?


    Thanks,

    No, because it can't be unless they reformulate Microphen. The dev agents used in a liquid concentrate have to be more resistant to hydrolysis and some of the other ingredients have to be more soluble (i.e. you can pack in more gm/l).

    It is however as close to liquid Microphen as is reasonably possible. Microphen may deliver a tiny bit more speed (well under 1/3 stop, inside experimental error for most of us) and any variation in formulae gives different tonality.

    Yes I have developed Delta 3200 in both and fractionally prefer Microphen, but I may have been seeing what I wanted to see and the difference ain't big enough to make me go back to Microphen from DD-X.

    Cheers,

    Roger

    Roger that, Roger.
    ;-)

    Thanks. I'm shooting a lot of Delta3200 these days. Here in the UK, DD-X is running 12 pounds sterling per bottle. A box of Microphen is a lot cheaper and if the results prove to be to my liking it may be a good alternatve.

    thanks,

    Dear Roger,

    "...but I may have been seeing what I wanted to see..."

    We should all be so honest with ourselves when making such comparisons (along with pretty much everything else!).

    Not really, but DDX coincidentally uses similar times.
