I have an S1000. Traded in a Lex MC12 for it. Right away I noticed a huge difference in audio. The Krell rocks. However, it's not as user friendly as the Lex. The Krell menu could be a lot better. That's not a huge deal. I was told Krell will have upgrades to HDMI 1.3, Dolby True HD and so forth by the end of the year. Well, that's come and gone. If you check their website and download the pdf, Krell is saying early this year they will have all that. I'm pretty excited about the new super beast prepro from Denon, the AVP-A1HDCI.
