Have you ever tried a pair of speakers and said this Is the last thing I will ever need.

I'm probably going to horrify most of the folks on this thread. 

I started out in audio when I was 14 with a Lafayette pair of speakers, integrated amp and a Garard table with a Stanton cartridge. 

When i was 23, I swapped a pair of Warfdale bookshelfs for a pair of Altec Lansing 604Cs. 

I added rhe Mastering Lab Crossovers. 

I've had the 604Cs for 39 years. I'll have 'em for another 39 years. Nothing beats em for the money, or at a price multiple of 20 times the amount that I have ever heard. Nothing comes close, IMO. 

Also: There's something to be said for your ears getting tuned to a pair of speakers. I don't know why that concept never comes up. 

Tuned ears?  That explains my lifelong pursuit to get the sound back that I heard from my brothers Bozak B-313's!  Only recently have I got together a combination that delivers the emotional content with the increased fidelity of modern design.

Sure.  Quad ESL 57s.  After a few weeks I added Townsend supertweeters and a pair of REL subwoofs, but basically ... it was the perfect system.

If I get rich again, I'll buy a newly refurbished stacked set of 4 from Quads Unlimited (or the German co.).  Cost will be well under 10G.

 

I researched speakers for about two years before making my final decision on a pair of B&W  N802's which I bought brand new in 2005 from the good folks at Audio Classics and they are still my main speakers. I have no regrets at all with these speakers and they will never leave my system. Oh, I have other speakers, but these beauties will remain with me until the end and will be left to my son.

Btw, I recently had my Altecs rebuilt: new accordion surround, woofer, spider, high frequency driver. Caps in the Mastering Lab crossovers replaced with Jensen foils. 

Made a difference, even though there was nothing wrong with anything, if judging just from appearance.
