So far,I'm impressed. It isnt broken in yet, but i'm really impressed with the amount of fine detail it presents. It does not sound "solid state", tho it is a little "drier" than my tube pre. The soundstage is not as wide,but again, it is still breaking in. The unit is gorgeous to look at and built like the proverbial brick shit house! It seems "quicker " than my other pre, and really does a great job of presenting the leading edge of sounds and separating instruments without being cold or clinical. In a nut shell, I am quite impressed so far,and having been using tube pre's the last 20 years, I must admit that I am surprised by what I have heard so far. I' will update in the future if you would like.
