Over 90 tube amp topologies examined, further evidence of how audio output transformers inescapably present limitations and compromises. Menno Van der Veen presented at 118th AES a paper detailing a universal audio output transformer system that “includes all possible variations in topologies. The system contains 90 variations (at least) and some of them have never … Read more

What is “sound quality”? Measurement Mania Not long ago, and presently in many circles, sound quality (“SQ”) was said to be best represented by audio systems amplifying with the lowest Total Harmonic Distortion (“THD”) measurement. Overlapping the THD focus was realization and consideration of Transient Intermodulation Distortion (“TIM”, AKA Slew-Induced Distortion “SID”), also a quantitative measurement said to … Read more
Sound quality (“SQ”) concerns the subjective psycho-acoustic perception of sounds and music. It’s something we all hear and enjoy differently. Join the journey.
