Heed Audio Si, PRE, PS, DT.......

For music lovers only !? What do you know about it in the US ?
It's not on your list, but I owned a Heed Quasar phono preamp and thought it was exceptional. Frankly, I preferred it over the much more expensive Pass Labs XONO preamp.

Based on my experience with this unit, I would not hesitate to recommend looking into Heed's other offerings

Two dealers I'm aware of are Audiofeil International (Clarence, NY) and Blackbird Audio Gallery (San Diego, CA).
