If the capacitance of a cable causes rolloff, is that an artifact?

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.

I used to think that power was power with only minor differences in the sound. However in trying to decide on the best amplifier for my Thiel 2.4s I've auditioned the Bel Canto m600s (their current production monblock), the Bryston 4 cubed stereo amp, and the Pass x150.8. They were PROFOUNDLY different. The Bel Canto rather oddly was very recessed the dark sounding, the Bryston was a little shrill with very little mid range "meat" on the bones but the Pass was JUST RIGHT. Honestly, I'm being a little sarcastic here but these were not subtle differences. I left the experience feeling that the "electrical" handshake between the power amp and the speaker is considerably more complicated than I originally imagined. Thoughts? |
@pwhinson The Thiel is a low impedance speaker, below 4Ω for most of the range with two steep peaks in the bass. https://www.stereophile.com/content/thiel-cs24-loudspeaker-measurements An amp to drive these speakers should be happy with a 2Ω load. And what speaker wire do you use? |
