About fifteen years in the making. Beginning with an iPod and headphones, with dozens of iterations to prove once again it is a system and every component counts.
By far the biggest changes were the Woo WA5 with Takasuki 300B tubes... the Aurender N100 Music server and the upgraded Ayre DAC.
I also still have some of the stuff I used to get here. Woo WA6SE, several other amps, DACs, LCD2 headphones, Beyerdynamic T2 headphones... etc.
That's a nice looking headphone system you have there. I enjoy headphones so much, that I sold my 2-channel set up many years ago. Which power cord do you use on your headphone amp?
