afaik - all references to a 24bitoademodsbm1 are innacurate. i think it started when people were trying to differentiate between the third and fourth mod. the former adresses the brickwall issue, and the latter is a rebuild of the linestage path, replacing the opamps, rca female jacks (i think) and some other stuff in that chain...
but it was never a 24 bit mod. i understood that the electronics in the unit itself did not allow for 20 or 24bit output, and that is why a simple chip swap didnt do the trick...
neutrino's sbm1's are the first ones i have heard of actually having a different chip...
i have seen talk, however, of "toddmod" sbm1 units (several years ago), but know nothing about what those mods entail...

there are many a/d converters that are capable of 24 bit, although none as small as the SBM-1.
Just for clarity's sake, since one could interpret this as indicating the SBM-1 outputs 24-bits: the SBM-1 does not output 24-bits.
thats how i read it
even though i know nothing about the smb1
since we are on the tpoic kinda--if a product is made for taping such as the smb1, why does it need to be modded?
i understand why the ua-5 did but some of the other oade mods i haave rean about i don't know what the difference is
mainly to improve the quality of the components used...
