About the WA-412 Modification Service:
Like all Warm Audio pieces this design is made in China with a number of corners cut at the component level that leaves this classic design wanting.
The implementation in the design, when compared to the beloved 1970’s version, sounds harsh with a high noise floor, lack of audio mojo and low end response to our ears.
Like a lot of Warm Audio pieces these sound great to the ears for those who have never heard an original design or used one in session but for those that know better Revive has your desire in mind.
Our goal with the modification is to push the design to the maximum performance level and remedy the above listed issues to satisfy even High End studio Engineers.
On these units we have two tiers of modifications.
Basic Package $300:
We do a complete audio path upgrade using premium parts for lower noise and higher headroom as well as lower distortion throughout the entire circuit.
This lowers noise, helps musicality and furthers the life of the design as well all know Chinese parts fail right out of the box.
All Audio caps are swapped out for better performance using Panasonic Parts to start.
The noisy power transformer is replaced by a premium Toroidal.
Bypassing is performed where necessary for lower noise in the Mic amp.
Power supply modifications are also performed for the lowest possible noise figures in the overall design and better current delivery.
Premium Package $450:
This package includes all of the Gold package options but also includes our low noise 2520 Opamp upgrade for all four channels, which lowers the noise figures even further, refines the low end and top end response for the full API312 experience.
So about the Results:
The service increases the headroom of the unit, widens the frequency response, lowers the noise and increases the clarity a great deal.
It also lowers the distortion figures considerably, smoothes out the audio character, increases the low end response to be closer to the original design and will leave a smile on your face.
