I have been watching the LMC-1 debate lately with some interest, and I've had a few concerns about it. The bootup time is pretty shockingly long (11+ seconds just to bring the unit up, plus the time spent winding up to the last volume setting), and the acquisition time sounds reminiscent of Outlaw's 950. The fact that they advertise Pro Logic II and IIx makes me really uncomfortable (which is why I've made a number of posts about the subject) because it feels like false advertising: Pro Logic II and IIx are
supposed to work with Dolby Digital signals and I've failed to find even one other product that is unable to do so. Toss in the inability to do firmware updates in the field, and I just get a bit uncomfortable with the product - even before factoring in some of the feature omissions made to reach the desired price point.
As for sound, we've not yet heard what DACs the LMC-1 ended up using. We know what DACs the 990 has, and they are quite good - in fact, one of the DMC-1's biggest proponents (DOJ) compared the 990 to the DMC-1 and found
very little difference sonically. I doubt that the $500 LMC-1 and the $2500 DMC-1 are sonically comparable enough to make the 990 a sonic downgrade from the LMC-1 -- in fact, it's most likely going to be a sonic improvement for both movies and music as well as a feature upgrade (start-up time is around 2 seconds, acquisition time is somewhere under half a second, PLII and IIx behave as Dolby intended, input names can be edited, firmware can be updated in the field, and all the other stuff in my
SSP chart ). If the LMC-1 isn't working out with you from a feature standpoint, I think the 990 would serve your needs very nicely for features and sound.
