Phono Box ultra 500 MM/MC – Luxury and audiophilia combined!

Pro-ject’s Phono Box ultra 500 phono preamplifier is named “500” to celebrate the 500,000th Phono Box shipped. These limited edition models (only 500 will be made), put the S2 Ultra’s design in a copper clad enclosure body for improved shielding against against high frequency interference. The copper chassis is then covered with a luxuriant polished chrome

Phono Box ultra 500 is like no other phono preamplifier in its segment. The "500“ in the name as well as the general 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 preamplifier:

The polished chrome surface outshines every competitor in this price segment and offers 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 offering a fully discrete, OpAmp less, design, which enabled us to realize an incredibly harmonious sound.

On top of leaving out operational amplifiers we decided to use polystyrene capacitors, which significantly contribute to the high end sound Phono Box ultra 500 offers.

These capacitors are known amongst audiophiles as the holy grail for phono preamplifiers.
