Jupiter Vitamin-Q Silver foil Series
Paper in Vitamin-Q oil capacitors

Sonic Bliss.

Silver Foil and Vitamin-Q are beautifully matched with added dynamics and balance that accompany a surreal quality. Jupiter Silver Foil in Vitamin-Q is the antidote for Audio-Nervosa.

Silver foil recreates a great sense of space, recording height, width and depth are very much more apparent with a great sense of ease to the powerful flow. Weight and dynamics express effortlessly as musical air fills the room like no other capacitor. They are the lushest of all paper-in-oil capacitors, with a velvety midrange and creamy liquidity that is addictive

Vitamin-Qs portray less dramatic transients sounding, with a slightly softer top and bottom end than the Comet Type.

Jupiter Paper in Vitamin-Q oil.

These capacitors utilize the same polymerized impregnation fluid developed by Sprague in the 1940s. Hermetically Sealed and processed under a deep vacuum for several days. Hermetic sealing keeps oil from leaking out and provides protection from ingress of moisture to ensure long life. Glass to metal end seals are soldered into tin-plated brass tubes to form leak-tight joints. Jupiter Silver Foil Vitamin-Q capacitors are built to Mil-Spec standards yet developed and refined for the ultimate audio experience.

Application Notes:

For best results keep capacitors as cool as possible, use common sense. Do not place next to or touching hot resistors or under-chassis signal tubes that get hot etc. This is good practice to follow with any capacitors, especially paper capacitors. Generally for every 10 degree C increase, component life is diminished by half.
