a ways back, jack offered to build me one. 8 tubes, 4 for each channel, only XLR outputs (no SE), 2 volume controls, but not stepped. he even had a preliminary design, but it fell through. so he has thought about building one. whether he ever will though is another question.
An advantage of the LE is that Jack can have output transformers tuned specifically for dynamic cans, as there are no speaker out to consider. I think Jack can even have output transformers dedicated to high and low impedance cans - and offer a no compromise design ?
Very attractive price considering it is a 300B amp, the build quality and multiple inputs and dual voltage.
