Quote: Originally Posted by MikeW Yeah, I think im hearing the dac noise, however it still does not explain why it is dramatically cut when I remove the Reclocker board. Should I experiment with putting more resistance at that position? Am I not understanding something, pat said he made...

Quote: Originally Posted by MikeW yeah, I saw that, it looks like he put a couple 2k resistors on there. But I don't know what value his original SMD resistors are. It looks like 680 is the correct value? It's confusing. There's another set of resistors above these, that are also...

Tried Tony's FRM (Film Reservoir Mod) Friday night and yes it did bring out the liveliness from the Chamelon, BUT, I later noticed I lost some bottom end from the DAC which mine system doesn't have tons of bass to begin with... so out FRM comes and my bottom end came back! Then it occurred to...
