NVA Passive Control Units

NVA's passive control units are designed with one aim in mind - to produce the smallest possible signal degradation. The passive concept is a logical extension of minimalism. Where a minimalist amplifier shows better audio performance through eliminating tone controls, filters and loudness switches, NVA goes one step further.

Using a high specification cermet potentiometer which we believe is unique to NVA, a heavy-duty switch, gold phono connectors and carefully tuned short runs of the best quality cable we can find, the P50 and P90 have repeatedly outperformed passive and conventional pre-amplifiers costing many times the price.

And for the ultimate sound quality we also provide the option of by-passing the switch entirely, through a set of direct input connections. We believe you'll be surprised by the difference.
