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.
Note this unit has the stock transformers with our full circuit upgrade which includes all transistors, capacitors, tweaks etc.

For those that will inquire, we recommend our circuit upgrade over a transformer upgrade on these designs for performance reasons. 

In our broad experience, the transformer upgrade only changes the character of these units but does not increase their performance for the most part so customers will get a lot more bang for the buck with our circuit upgrade. 

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.

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:)

MP73X2
Dual channel mic pre-amplifier
Based off the Classic Rupert Neve 1073 preamp the Mp73X2 is a dual channel, discrete, transformer coupled preamp that sounds excellent on any number of sources, with excellent headroom and warmth. It comes complete with custom transformers from Alctron for both the line and mic inputs as well as the XLR output.
Product introduction
MP73X2 Is a fully discrete signal path with two separate transformers for the input and output that offer a tone of analog warmth and further enhances MP73X2’s performance compared to other designs in their price range. The discrete path is a tried and true classic and coveted design in the audio industry for a reason
