Supratek or Don Sachs - which way to go?

Both are noted for excellent sound.
But internal photos tell a story too. Between the two the Sachs is hands down the winner. Don shows the internals on his website. Google 'Supratek internal photos' for views of the other.
Is there a particular reason why its come down to these two preamps?

Nice response @

@atmasphere Wow, quite the scene inside there...

The question above about how or why I narrowed my search down to these two is worth thinking about. To explain, I need to share a little history.

A friend had bought a Prima Luna integrated to go with his quad 2805s. So initially I was looking at one of the Prima Luna preamps. Through researching and corresponding with others on various boards I came to think the 6SN7 was the tube I wanted as the centerpiece of whatever I bought. 

I'm grateful for the recommendations posted by others on this thread, and I'll continue to read about those preamps. But in summary, everything I've read about the two preamps I mentioned above suggests that they are headed in the direction I want to go. But I'm still very much a novice, and am eager and ready to learn more.

I own both, Don's Kootenay 120 KT88 Amp and his DS2 6SN7 Tube Pre and they are very impressive in their build quality and sounds Amazing!

You will be a happy camper going with Sach's equipment...
