Another view of damping factor?

so it would seem odd to make what is typically the longest cable run/loop in the system (the speaker cables) a current mode transfer.

One of the advantages of current drive is (claimed) to be much higher immunity to losses in cables -- including interconnects (ref Krell's current based scheme)

Implementations I'd seen previously required sensors on the speaker-does the book discuss something that will work with any speaker? Or must be designed as a system?

The sensors are a band-aid for using woofers designed for voltage drive. All amp/speakers need to be designed as a system, but we live in a world (since the introduction of transistors and the acoustic suspension speaker) where most systems are voltage source based and it has come to the point where most people forget that there is more.

Interesting reading indeed! And a good point about NFB and feedback. Don't tube amps have less feedback? Maybe that's one reason they have such a nice sound.
