Many speakers - Solution to a constant upgrading
I came to a conclusion that since different music sound better on different speakers, we need a few sets. We can get Niles speaker selector and switch from one to another as music demands - we will our listening more of the times, and not get that upgrade itch as easily.
For instance, voice sounds better on speakers with low Q values - the spring in the woofer loaded softely - not too tightly. This gives a richer sound. Especially true for classical singers - when they sing loudly and make a sudden crescendo, it still keeps sound soft so as not to bother you - as with speakers with high Q value - hard spring loaded. This is especially true if you listen at high volume - on low enough volume, you might be able to get by without pronounced distraction.
High Q-value woofers do certain acoustic instruments well - like piano, guitar, and other string instruments, because they sound more realistic. The springy feeling one gets from the live performance is captured. However, not too many have a refined sound. Old JBL 4312 for instance have alnico woofers with high q-value, but still sounds refied - unlike many of the todays speakers with high Q-values. I like them even better than B&W top of the line series. Old Tannoys with tweeters built in at the center also sounds refined (even better than the JBL). I am talking about the Tannoy gold and not their newer plastic woofers.
If you have both, than you can switch from one to another, and get the best of the both worlds, as music dictates. But keep in mined, that no matter how much you spend on your system, it can never be completly like a live performance! Don't try to follow that dream - your bank account will thank you, and your loved ones.
However, if you have many sets of speakers at your listening pleasure, you will be satisfied more of the times, and hopefully this will solve the ever upgrade bug.
Hope you find your sonic nirvanah...
