Cary for a Cary ....B&W for a B&W???

First I would like to say agian! "Hellloooo Audiogon!" I read these forums all day!!!" And Yes that’s right ..like most audiophiles I now and then suffer form that “upgrade itch”. So I have some questions on my mind! Before reading further I hope you all take a look at “My System” to see where my system stands and how to advise me!

Firstly I would like to address my amplification. I have a AES/Cary super amp DJH….I absolutely love this piece but I know there is more! Musicality transparency all the good stuff. Now while I know this is top of the line for the AES line it is not top of the line Cary. And I have to say “I love that Cary Sound”. Now I hate those “why so many for sale posts” but I am starting to ask myself that question about the Rocket 88 Cary amp? My question is …”Would this be and Upgrade from what I have” I have listened to this piece but not in depth. They are in the similar price range used ..so I ask myself “why not upgrade?” Someone tell me? Any other opinions amps ideas?

Secondly I have B&W CDM 7nts. I LOVE them yet want more! Would I be satisfied with Nautilus 805’s ? and in the future maybe a sub? Is it as easy as they say to integrate a sub with monitors like these? If so how? Basically I am looking for the same attributes as stated above!

Thanks For all your Help…!
