Does Parts Connexion respond to emails? I emailed them a while back to ask about mods they did on a piece I had. They refused to answer me. I called them twice and got the runaround, said the "owner" would call me back and never did. They simply refused to have any communication about mods they did.
Krell XD technology
Interesting article at Stereophile regarding Krell's XD technology:
https://www.stereophile.com/content/krell-k-300i-integrated-amplifier-sonus-faber-olympica-iii-louds...
I quoteth it thus:
With 0.035 Ohms of output impedance, this would be a damping factor of around 230. I'm curious for two reasons:
I'm not a Krell fanboy, haven't heard them in decades. Just saying from a tech perspective this was an interesting read for me.

I quoteth it thus:
The key insight, which Goodman told me was discovered in the course of developing the K-300i, is that "lowering the output impedance below traditional norms" results in "substantial sonic improvements."
With 0.035 Ohms of output impedance, this would be a damping factor of around 230. I'm curious for two reasons:
- I have seen evidence that SS amps are more susceptible to impedance variations than we think, and that this accounts for some of the changes we hear in speaker cabling.
- I wonder if it's something besides better feedback, and they're just afraid of calling it that?
