K1000 Output: that's right, baby! Last summer, Jack and I were getting my WA5 300B monos spec'd. My Woo, should I resume completion of this project, will have the HE-6 leashed up to separate L/R K1000 Outputs.
I moved in another direction entirely last summer, but may resume the project at a date TBA.
The WA5 with upgraded tubes is a great headphone experience. I love it with my HD800 (and LCD-X), but what it does with the HE6 is something else again. I had no idea what this headphone could do until I plugged it into that K1000 socket.
Ear-speakers - exactly what the HE6 is.
