Does anyone care to ask an amplifier designer a technical question? My door is open.

I closed the cable and fuse thread because the trolls were making a mess of things. I hope they dont find me here.

I design Tube and Solid State power amps and preamps for Music Reference. I have a degree in Electrical Engineering, have trained my ears keenly to hear frequency response differences, distortion and pretty good at guessing SPL. Ive spent 40 years doing that as a tech, store owner, and designer.
.
Perhaps someone would like to ask a question about how one designs a successfull amplifier? What determines damping factor and what damping factor does besides damping the woofer. There is an entirely different, I feel better way to look at damping and call it Regulation , which is 1/damping.

I like to tell true stories of my experience with others in this industry.

I have started a school which you can visit at http://berkeleyhifischool.com/ There you can see some of my presentations.

On YouTube go to the Music Reference channel to see how to design and build your own tube linestage. The series has over 200,000 views. You have to hit the video tab to see all.

I am not here to advertise for MR. Soon I will be making and posting more videos on YouTube. I don’t make any money off the videos, I just want to share knowledge and I hope others will share knowledge. Asking a good question is actually a display of your knowledge because you know enough to formulate a decent question.

Starting in January I plan to make these videos and post them on the HiFi school site and hosted on a new YouTube channel belonging to the school.

An extremely generous offer. Thank you.

What is it, from a technical standpoint, that allows good tube amplification to reproduce micro dynamics in a way that is much closer to what I hear in live music? I refer to the ability to reproduce the seamless dynamic gradations in volume (especially very subtle gradations) that give music a sense of aliveness; not simply the ability to play very loudly. I know some will disagree, but to me tube amps generally do a better job of this than solid state. The attributes of tube amplification are often described in terms of tonality, dimensionality, staging, but the thing that draws me to tubes more than anything is the way they reproduce dynamics. I generally hear more dynamic nuance (realism) from tube amplification. Thoughts?
