Obbligato 0.68uF 630Vdc Copper Series Film Cap
These Obbligato film caps have a solid copper case, soldered copper lead-out wires and individually wrapped. All measure very close to rated value, max 5% but typically 1-2%. Wound tight with no voids and give a very transparent, smooth sound.
They certainly weigh a ton due to the thick copper casing and feel extremely solid; they do not sound cheap, either. The overall sound seems linear, more so than the PIO caps, with very nicely airy and extended top-end. There is no hardness or glassy artifacts often found in really cheaply-made metalized poly caps while retaining speed and transparency.
