Member of the Trade: JM Audio Editions/Headphone Modifications
As an update I understand Valentin has run some tests and shared graphs with me with the mod he did in Russia to emulate the soft fluffy dot and open ports to be removable - he promised to get back to me with a sample so I can compare his revision and mine- and I will in turn send mine back for more tests (I just dont want to give it up! but so is the pursuit of perfecting this upgrade) he said a limited amount of editions may be made and asked if it would be okay if he called the new modded HP to be called the Gjallarhorn JM Edition (in my honor he said) ... wow what an honor it would be... I just want to do more tests to make sure we nail it as good as it could be together- again I am not making any money on these Kennertons - only want to see the best put forward for all...
