Second, the KAV-250a isn't that new a product, at least for Krell (who seems to specialize in rolling their product line every 2-3 years). I think the reason it's being discontinued is because they've come out with upgraded versions of both the 2-channel and 3-channel 250 w/ch amps that also have the new cosmetics. I believe it's been a very successful product for Krell and, as with many other Krell products, good prices are to be had with the model rollover. I agree that it won't help with the used prices, but if you're buying and take it into account, a Krell will definitely retain a fair amount of value over time.
I agree with Angela that the Krell is an excellent choice if you like rock music - I listen to a lot of rock music and watch a lot of movies, both of which naturally have a lot of in-your-face sound to them. I listen to a lot of jazz and vocals as well, and I think it does a great job with them as well, but I haven't compared a bunch of amps so I may really be missing out. I'm sure that at $2K, there's a LOT to choose from and many models that would be excellent choices. I also don't know how difficult a load the Mirages are - the Dynaudios really like their current which is one of Krell's major strong points. -Kirk
