I had SF SFL-1 (my 1st tube preamp), SFL-2, Line 3 and Power 3. With my favorite NOS Philip Holland / Amperex 6922. it's not dry or sterile.
I had the Line 3 and Power 3 upgraded to SE+ by PCX. It's an improvement over stock but not worth the $$.
In the Line 2 + upgrade price range, checkout an used EAR 868, Audio Valve Eklipse and ModWright.
