Phono Box Ultra 500 is like no other phono
preamplier in its segment. The polished chrome surface
outshines every competitor in this price segment and
oers undeniable aesthetics. Underneath this surface
we have used a copper body, which is known to have high
qualities in protecting against high frequency
interferences. The internal design has been
reworked.
We are now oering a fully discrete, OpAmp less, design,
which enabled us to realize an incredibly harmonuous
sound. On top of leaving out operational ampliers we
decided to use polystyrene capacitors, which signicantly
contribute to the high end sound Phono Box Ultra 500
oers. These capacitors are known amongst audiophiles
as the holy grail for phono preampliers.
Phono Box Ultra 500 - Luxury and audiophilia combined!
