About the design:

The Heritage series is a budget conscience reproduction of Neve classics that utilize machines to build the PCBS using surface mount technology.

They use a DC inleted power supply (over a classic power transformer), AC to DC design for the 24V and +/-15v rails. 

SMD technology is quick, inexpensive and easy to build, but is NOT notoriously great sounding in audio applications.

They often sound clean, but mid forward, small and brittle.

 
The Symph EQ series designs: Stock, these units are not very clean and are a bit brittle sounding but due to their use of all SMD capacitors and transistors. 

Most users find them to be very mid forward, lacking the warmth, low end and depth of a real Neve or BAE. 

The Goal is to clean up the noise floor, add great clarity and extension and better depth of field. 

See our Youtube channel for before and after clips. 

On the Symph EQ we offer both a Full Circuit path upgrade that includes all SMD caps, Burr Brown opamps, High performance output transistor, noise reduction, power supply modifications and more. 

About the Modifications

We are offering the most comprehensive and Cumulative modifications on these available on the market.

What we do to these little boxes is essentially pull all of the SMD Electrolytic capacitors out and install Low noise, high performance Panasonic capacitors for more warmth, lower noise and better dynamics.

Various values are adjusted throughout for better performance in all sections.

High Performance Burr Brown opamps are add in the filter sections that use them. 

The output 2n3055 in this design is a SMD mount to-220 style which is another reason for the mid-forward sound. 

Noise Reduction is applied in every section of the design. 

We pull this part out and mount a proper low noise, high headroom version and reset the bias.

You walk away with a wonderful sounding preamp with boutique modifications that will make pro studios happy at a price that doesn't disrupt your month.
