Hi Sebatron, Welcome! I enjoy discussing thoughts about the design process for equipment, and was wondering if you could share your views on the balance between "scientific" measurement versus "using 'yer ears" in the lab. For example, sometimes a circuit which "measures well" or seems "technically perfect" will often seem fatally flawed for audio use. And a circuit which has a very "poor" technical spec will be loved and adored the world over for a specific "sound". I know from experience that many potential customers and reviewers like to see a good "technical specification" and the stats for distortion, noise floor etc. are quoted and mis-quoted. At the end of the day a design has got to sound good, be robust electrically and mechanically, and be versatile enough for many users to appreciate it. ...any thoughts on this (highly debatable!) subject? All the best for your new forum, :c: Mark -------------------------- "Oscillators don't, amplifiers do....." Anon.
