I'm looking for a pair 1.0µF Sonicap Platinum capacitors. 
Wow, only $164.95 each at
http://soniccraft.com/sonicap_platinum.htmYou're paying for the hype and a +/- 5 percent tolerance, but what the heck, it's only money, your money.
Why not try some Jantzen Silver Z-caps? Better specs and a heck of a lot less hype. Jantzen Z are 2 percent and way higher working voltage.
"Jantzen 1.0uF 800V Z-Silver Capacitor
Jantzen Silver capacitors are possibly the most detailed caps on the market. These caps are constructed of a specially wound metallized polypropylene to minimize inner vibration, which keeps microphonic effects as low as possible. Silver Series caps also feature high purity silver leads for the absolute best signal transfer, resin-sealed end caps to protect against humidity, and flame-retardant tape wrap. The result is a reliable and consistent product that facilitates the construction of high quality, precision crossovers. Silver Series caps are natural sounding without audible coloration of the audio signal, delivering an authentic soundstage and neutral tonal balance. Sonically, they behave more like a fine piece of wire than a capacitor. Truly, an outstanding audio component! Rated at 800 VDC, 2% tolerance."
