Thanks a lot for the very clear explanation.Just to quickly comment here. Transformers all have an inherent imperfection in them such that the lower in frequency you go, the more harmonic distortion they produce. It’s just the physics of it. How much power it takes and the level of harmonics they produce depends on many factors in the construction of the transformer. And these harmonics are real. You can see them on an FFT analyzer. The overall effect one hears would not be the equivalent of, for example, engaging a fuzz pedal. It’s a much more subtle effect, but still very real. It doesn’t change the level of the signal (I.e. it’s not the same as boosting a bass eq)but rather adds texture and presence to the signal by introducing harmonics of the root note that weren’t there naturally. They also exhibit various levels of hysteresis which adds some subtle harmonics in of itself from this aspect of transformer behavior. There’s a reason a lot of studio engineers will run their final digital mixes thru analog gear such as compressors with transformers in them, often times without even engaging the compressors themselves. It’s just to get what they refer to as adding the “glue” to the final mix. So there is no black magic here, no pixie dust, just some added harmonic enrichment to the signal itself to add some harmonic excitement and presence to your tone. That’s it!
We didn’t invent any new technology, but rather utilized existing technology in such a way as to give our HP2X the added texture and harmonic enrichment transformers are known for. What we did was worked with Cinemag to design a transformer that would work in our current design and yield the harmonic spectrum we were striving for. Hope this helps everyone better understand the thought process behind the design and why we did it. It was an exercise in good old fashion engineering, not black magic or snake oil!;-)
An A/B demo of the same bass line with the HP2 and the HP2X would help understanding even better the difference IMHO.
