XL, I happen to have a couple Spec 1's in the mancave, both restored to EW's specs. Let me get caught up and I'll run a complete set of tests on it and publish here..
I've run Freq response, distortion, residual noise, phase lag/lead, crosstalk, and signal to noise ratio on both of my Spec 2's after restoring and in both cases all measurements were superior to the factory published specs...
What did you have for test equipment??
Not laughing....
Do you have the operating manual? Would you like some testing info? Or did I send you those already?
XL , that wasn't what I meant, I have two books on pdf that are of audio testing in general. PM your e-mail and I'll send em to ya....very good reads to help understand why things are done the way they are....
Fundamentals of Modern Audio Measurement by Richard Cabot, and Audio Measurement Handbook by Bob Metzler....
Did they go through??
