RNM4 - in reply. I really like the 7s. I don't really have the space for them though. Way out in the room and in the best listening seat, they just simply disappear. More so than with virtually any other very large speaker.
I also think the Totem Mani's are great speakers (not the model 1's nearly as much and way over the Forrest). But I haven't listened to the Mani's with Krell (in my system), so I could not comment, but it seems like a good idea. They can get down there (for their size) with their 2 woofer configuration. They throw a great image too.
I went the D amp route and listened to a couple and bought a pair, but after living with them for a bit of time, just felt that they missed too much of what I needed to be fully satisfied. While I became too closed minded to the technology, I would mind see what the new versions are offering to see if they have overcome what I found to be the long term deficiencies of the technology.
Krell/Thiel are not bright if you system is up to it, more detailed than some people may like - certainly. Don't kill your Thiels by running Cardas Golden (tried that and ran toward the hills when a dealer recommended it with a CDP).
