Tvad has the ratings correct. Funny you should mention image sharpness and ambience. I recently replaced the MIT PPMFX capacitors in my Joule Electra preamp with Jantzen Z-Superior caps. While I am hearing improvements in all sonic parameters, image focus and ambience are absolutely astounding after this change!
Many cheap caps sound smeared and hard, quality caps reduce this by a much greater amount than cables, tubes and other tweaks IMO. If you are willing to change out the caps this may be your answer, this may also cost much less than all the cable changes.
