After taking delivery on a Berg IP112ER I'm now looking at the ultimate in high-end preamps. Something tells me I should look at the Millennia stuff and I figured that the STT1 is at the top of that tree. But does the cheaper TD1 have anything sonically unique that the STT1 cannot reproduce? Some players say they have one of each, why? I'd go with the TD1 but I think I would like everything (including compression) in a single unit. So, can anyone tell me what benefits the TD1 has over the STT1?
