Audiophile phono preamplifier with polystyrene capacitors

ThePhono Box S2 Ultra is a unique phono preamplifier in its class. The pursuit of the highest possible sound quality at a reasonable price was the driving force behind the launch of this audiophile phono preamplifier within the S2 series. The solid metal housing protects the unit from interference and the internal construction is as perfect as that of much more expensive phono preamps.

It is a completely discrete solution that results in an incredibly harmonious sound. The Phono Box S2 Ultra is a luxury and audiophile device all rolled into one!

In the design, operational amplifiers were omitted and polystyrene capacitors were used, which contribute significantly to the Phono Box S2 Ultra's superior sound. These capacitors are known among audiophiles as the holy grail for phono preamps. The split RIAA curve allows for accurate RIAA rendering, a luxury not offered by many other, even more expensive phono preamps.
