The FiveFish Studios Passive Equalizer, using Carnhill Inductors, for 500 Series racks. -- Model PEQ-503

Very smooth sculpting of sound, no setting is bad. Silky Low Freq and Mid Freq control.... thanks to those huge Carnhill/UK inductors (same kinds used in Neve EQs). High Freq filter also outfitted with additional inductor for better control and shaping of the high frequencies.

Have you tried Evox PFR polypropylene film and foil caps? Mouser started carrying them a couple of years ago in ranges covering 100pF to .01uF with a 5mm lead spacing at 65 or 100 volts. I've seen and heard them used in phono stages and they cost about the same as Wima caps. Epcos polyester film caps are also pretty good when you need a larger value say 1-1.5uF for opamp supply bypass.
