Speakers to hang on to for LIFE

I agree with Eyeballman's assessment of KEF Reference 105/2 speakers. I have been enjoying mine since 1982, and everytime I upgrade something in the system in front of them, they just sound even better. I may consider buying something newer at some point, but it will have to be a pretty amazing pair of speakers (and probably amazingly expensive too).

I've had these ADC Sound Shaper 3010 bookshelf speakers for going on ten years. They've certainly endured. I got them from my father who had them I think for 5 years beforehand. I'm only thinking of replacing them because the cabinet's cracked on both. I use them as a right and left channels.

Can anyone tell me more about ADC Sound Shaper? I know they used to make equalizers and other equipment. The speakers sound great, are three-way, have an impedance of 6ohms, and handle up to 150 watts. Frequency response is 24-28kHz.

I'm no real audiophile (my hearing doesn't allow for it). I have:

Pioneer VSX-D5095 a/v receiver (5.1)
JBL TXLps10 subwoofer
aforementioned ADC sound shaper 3010 speakers
Sony entry-level center channel and rear surround set
Momitsu 880 DVD/CD player
Scientific-Atlantic 8000 DVR cable box

I've had over 60 speaker systems, all types and sizes, over the past 30 years and I really like the Coincident line of speakers. Presently have a pair of Conquests that I plan to keep forever. May try the Partial Eclipse someday but still plan to keep the Conquests.

The first high end speaker is the last speaker I will own, that is the Proac responce 2. I think that this speaker does many things right. When matched with their respective Target stands & coupled with a good subwoofer they will make magic. I would prefer a pair of Legend's but they were not out yet. I also feel that an upgrade should not involve much additional funds since the Proacs are an excellent speaker in itself.
