I have the Digital Vanguard and although I don't understand a lot of the specs this amp is amazing for me. I have had Parasound for years and am sorry I ever put money into it, just lackluster compared with the Krell's performance. Open dynamic and musically stunning in my opinion. My older Vandersteen 2ce's have never sounded so good. I believe it probably comes down to system matching and integration. I'm playing with interconnects and cables now and having a blast!!
Krell XD technology
Interesting article at Stereophile regarding Krell's XD technology:

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?
