SONIQS PXX Polypropylene Capacitors

Specially developed to meet the audiophile needs of speaker builders, the Soniqs PXX capacitors are wound using a 6µm (250Vdc

rated) polypropylene film. After resin coating and heat treatment the insulated copper terminals are hand soldered to give the best

possible connection.

The inherently low dissipation and dielectric absorption factors of polypropylene allied with an excellent mechanical stability results in a

highly detailed sonic performance. The construction also results in a low self-inductance and ESR and the devices are highly stable with

regard to temperature and frequency.

 

Note, all are 250V DC rated and are in stock now.

SONIQS SAX Polypropylene Capacitors

Specially developed for the demanding audiophile, the Soniqs SAX capacitors are wound using a 10µm (630Vdc rated) polypropylene

film and then sealed in resin. Following a special heat treatment cycle, insulated copper terminals are hand soldered to give the best

possible connection.

The inherently low dissipation and dielectric absorption factors of polypropylene allied with an excellent mechanical stability results in an

extremely detailed sonic performance. The construction also results in a low self-inductance and ESR and the devices are highly stable

with regard to temperature and frequency.  If you want to upgrade your amplifier or preamplifier this is the way to do it!

Note, all are 630V DC rated and are in stock now.

SONIQS PIO Paper In Oil Capacitors

Soniqs Audiophile Grade PIO Paper In Oil capacitors are specially hand wound using high purity aluminium foil with oil impregnated paper dielectric, totally immersed in oil for optimum damping and acoustic isolation. Sealed in an aluminium can with hand soldered copper lead out wires, Soniqs PIO are ideal for use wherever high purity, low distortion capacitors are required for optimum signal transfer. The 'line' on the label denotes the end connected to the outer foil for those who like to 'align' capacitors to the source. These capacitors have been specially designed to pass the signal without any audible character being added to the sound. As a result all you hear is the natural, dynamic range of the original signal. Specially developed for use in valve amplifiers as coupling capacitors. Use in DIY kits, or as capacitor replacements in existing designs, vintage amplifiers and radios etc.  Note, all are 630V DC rated and are in stock now.
