How old is too old ?....

I am in the same position as a few others here. Upgraded the front end a year ago and am now not sure I'm getting the best from my 104.2's. The opinion here, ever so slightly, seems to be in the "get rid of 'em" camp.
Am trying to find someting that has a similar character with more openness.
My favourites thus far, in no particular order:

Linn Ninka
Dynaudio Audience 72
Totem Forest

First two in the same price range, the Totems 1K more but I like them the best. The Dyn closest to the KEF sound.

Will also audition Monitor Audio Silver and Gold lines. Can get them for near cost so can afford to go higher up the range.
The same dealer will also give me highly discounted pricing on B&W. Have never been a B&W fan but he recommends the new 704?

Amy comments on Monitor Audio and/or the B&W 704?

hifinut- the Silverlines use all Dynaudio drivers except for a german domed midrange, and like the Dyn, comes "closest to the KEF sound." I listened to Monitor Audio, new KEF, and B&W before I fell in love with the Silverlines (which I'd never heard of- thank God for Paul Bolin of the Absolute Sound ...It prompted me to audition them). Monitor and KEF did not have a seemless integration of the music, as if there were a phase issue with the cabinet or crossover. The B&W was wonderful. I just didn't like that metal hissy tweeter. It's personal taste. It's much smoother than the old metal tweeters, but for my tastes there is too much sibilance (on cymbals for example) in a metal tweeter. Just to let you know, the Silverline was $1000 more than the 805, but was worth it. If you can get it for less than a 705, it's a steal. I don't expect you guys to order it on my sayso, I just ask you to try to audition it. There must be a dealer or a 'gon member who'll let you listen. Come to my house...CA near Berzerkeley.

Hammy,
Was not familiar with the Silverlines either. Have looked at their website and reviews via eCoustic. Certainly seem appealing but, alas, well beyond my price range.
I'm in Vancouver, otherwise I'd come have a listen.

Some Hifi-reviewer (sorry, don't remember his/her name) once wrote: "There is no system that can't be improved by a hefty dose of music". If you're happy with the new sound, but still want to burn some cash, why not buy more music? Lp's, cd's dvd's, whatever. And if you really want to change your speakers: go out there, listen and compare, and find out if you think it's worth the money.

Hifinut- used Sonata II', are now 2500, about the original cost of the 104.2, and a spectacular buy. The original Sonata is probably cheaper, and is a spectacular speaker, with less bass (although it doesn't roll off until mid 30's). Sonatina or Panatella are cheaper still....If you see one on the 'gon and it's near Vancouver, take the time to go for a listen!
