I own the following:
Modwright LS-100
Don Sachs DS-2
LTA MZ-2
Atma-Sphere MP-3
The one that’s staying is the MP-3. All of them are very good, but the MP-3 is best in my system; not surprising, since my amps are Atma-Sphere M-60s. It combines the great tone of the DS-2 with the inner detail of the MZ-2.
I could live with any of them; the differences are small but noticeable. So is the DS-2 too good to be true? Not at all; it’s very good. Are there better preamps? Of course. Are there better preamps at the same price level? Only you can determine that.
A larger company would have a difficult time duplicating Don’s craftsmanship, quality, customization options, and customer service at anywhere near his price, due to their far greater overhead.
