Speakers to hang on to for LIFE

See, I already proved my point in my previous post! It hasn't even been six months, and I'm on to another speaker already! Eminent Technology LFT-8a.
Did the in home side by side comparison of the Magnepan 1.6QR to the Eminent Technology LFT-8's. The LFT's blew the Maggies away. No contest. The LFT8a's are my newest "speaker for life." Really.

I have had a pair of Teledyne Acoustic Research AR-9 Towers forever and still goin strong after a re-foam 2 yrs ago...these are 20 or so years old.

I have a pair of B&W CDM 9NT's. I've only owned them for about a year and a half. I don't plan on ever getting rid of them. I love them.

Got to go with Living Voice Avatars as David mentions above. They truly match up beautiful with my Audio Research tube gear and are astonishingly transparent. Love 'em.

My current pair of speakers are 15+ years old. They've been upgraded a few times within that period, and I'm going to be upgrading them again soon.

Driver technology has advanced, so new speakers may be better for that reason alone. (Assuming that the new speakers are designed well.)

Some parts of a speaker may degrade over time, so that has to be considered.

Changing speakers every 6 months seems excessive to me, and keeping the exact same speakers for 20 years also seems to be excessive. There's some middle ground that would be best.

If someone gets pleasure out of switching speakers every 6 months, I guess that's their business. But I'd just question whether they actually know what they're looking for, or are just trying new things in a random attempt to reach some nebulous goal.
