This is by far the most comprehensive modification being offered on the market. Hands down!

Some companies replace a handful of parts at the major bottle necks where we modify and adjust the entire circuit.

For customers that inquire, the Circuit modification will yield much higher performance results from the circuit than the transformer upgrade and is a better value.

About the Modifications

We all know these preamps pack a good price to performance ratio but with the modifications they simply sound excellent with better bandwidth, higher headroom and sound less muddy to boot.

The character smoothes out and the noise floor is lowered to a point where the audio is just right and a lot closer to the original Neve Design minus the Carnhill transformers.

What we do to these little boxes is essentially gut the insides.

We pull all of the transistors out and replace them with high HFE transistors for better bandwidth and lower noise to more closely resemble the original Neve design.

We then pull all of the caps out the unit and replace them with long life, audio grade Panasonic capacitors for even lower noise and better musicality.

The power supply is then upgraded for longer life, lower noise and better filtration of noise as the icing on the cake.

We walk away with a wonderful sounding preamp with modifications that we receive nothing but positive feedback about.
