What phono preamp are you using?

James1911,
Of the four you mention, the only one I'm familiar with is the Whest. The signature three I own replaced an older Sonic Frontier Signature tube phono stage. I like it much better in my system but can tell you it doesn't sound like a tube amp. If that is what you are looking for, the first 2 you mentioned are highly praised here. 

Pro-next Tube Box S2

Pro-ject 

@big_greg, any more insight into why Keith is only making a few more of them? It's probably one of the top items I think of as "someday soon".

Sorta funny, my reaction when I hear that is closer to cross the brand off my list vs. jump on the last one. Cheers,
Spencer

Spencer, from what I understood his supply of parts is running low.
