VAC Standard/ REN vs. Coincident Statement

Both manufactures VAC and Coincident get glowing reviews on there preaamps: Statement and Standard / REN

But what do actual users think of these pieces? How do they differ sonically? My initial thoughts:

Coincident statement--- VERY very transparent to source
VAC standard-- more warm sounding
VAC ren -- less warm than STD, with more transparency.

Mind you these comments are NOT from direct comparison, but a review of postings and rag reviews... thoughts
