GainWire Mk3 CFA pre/phone amp with very low distortion

Now after two years passed since the boards have been delivered to the ones who ordered it I would like to have some comments about build and listening.

I hope there are people with finished GW mk3, please tell me your opinion.

Hi all,


This preamp is first class and I warmly recommend it. I use the previous version mkii with great satisfaction while I'm planning to build the latest version too when my schedule allows it.


After that build, you won't need to spend more time researching on transistorized preamplification and you'll definitely focus on other part of your system.


Thanks again, Dadod, for this work. Music is alive again!

It passed more than one year from last post here.
Because there was some interest in the PCB for this pre/headphone amp I will ordered some more of it, quantity depens of interest.
There is a new improved layout revision 1.5.
Please put your order here if you are interested.
Damir
