Phono Box ultra 500 is like no other phono preamplifier in
its segment. The „500“ in the name as well as the gene-
ral availability, worldwide limited to 500 pieces, celebrate
the 500,000th Phono Box that Pro-Ject shipped in early
2018. We took this milestone as an occasion to create a
one-of-a-kind phono preamp:
The polished chrome surface outshines every compe-
titor in this price segment and offers undeniable aes
-
thetics. 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 offe
-
ring a fully discrete, OpAmp less, design, which enabled
us to realize an incredibly harmonuous sound.
On top of leaving out operational amplifiers we decided
to use polystyrene capacitors, which significantly cont
-
ribute to the high end sound Phono Box ultra 500 offers.
These capacitors are known amongst audiophiles as the
holy grail for phono preamplifiers.
Phono Box ultra 500 - Luxury and audiophilia combined!
