I can only speak from my own experience, and I’m not about to say or suggest that the Sachs is better than every other preamp in the land.
What I can say is that in the almost two years since it’s entered my system, I have been off the preamp merry go round with no urge to go back. What the DS2 does,it does as well or better than any preamp I’ve heard. But I haven’t heard all of them, and its character may not be everyone’s cup of tea.
In my system, it’s been magic. I keep an LTA MZ2 on hand for when I want something a little different, but the DS2 is my mainstay for now - and will be for quite some time, I think.
