How does one get off the merry-go-round?

Gonglee3, I thought Q was a measure of resonance of driver material -ie. metal rings and will have a high Q. Sounds like what you're talking about is suspension compliance or damping factor of the speaker.

Cdc - I am sure you are right too - my DIY book described Q value as the spring behind a woofer - if you press on it, some feel tight, and some loose (some have more resistance) I mean by high Q, a tight strong spring. This might not be a universally agreed on audio lingo, but you get the idea, no?

On with getting off the meery go around, there was a time when I tried to captured the "live" sound - but no more. I have bought too many components chasing that rain-bow, and when I stoped to think about it, it became obvious how one system cannot do all!

Different speakers have different color to their sound, and look at the different colors many musical instruments make. Pretty soprano of female voice is again different from the mellow deep baritone. The speaker that captures the high sounds of a stradivarius (violin) sounds piercing on soprano. So don't keep pouring more and more money into this hobby - like a $70,000 turntable for instance. I am sure it's a little better than a $2000 set up, but then it still ain't the real thing...

I ended up with a few sets of speakers doing different things well, and I go back and forth depending on the music and my mood, and I seem to have cured the upgrade bug for now - but it's fun to look for new things too - I have to admit.

Something else to consider are 2 things -

1) Room acoustics - treatments
2) Dedicated power line

Without taking care of these 2 things, you may be wasting a lot of effort and money. You are not hearing the best your gears can offer.

Another thing is to experiment with silver cables - more liquid sound. You can buy silver here on the audiogon and other places, and DIY - RCA and speaker cables.

You might want also to experiment with effects unit - I had a system that sounded too dry, and when I added Yamaha Cavit 50, and added effects, the sound became liquid and transparent. I saved the system from being sold. The unit is only midfi-ish, so I wouldn't call it hifi, but it could be what your 2nd system is lacking.

The qualities necessary for me to enjoy a system is:

1) Liquid
2) Transparency
3) Accurate color

If a system has these 3, they are listenable for me.
Of-course it would be nica to have these as well.

1) Luxurius decay
2) Dynamic (300 watts would be nice)
3) Class A or A/B amp
4) Harmonically rich
5) Deep and wide soundstage

If you know specifically what you are looking for in terms of audio-lingo, then you can get there, without constantly searching and upgrading.

I hear of many stories of an audiophile, who spends as much as a luxury car, only to do more listening on a $3000 second system, on a computer for example (low jitter). The experts tell us that if we do the homework, we can assemble a satisfying systme for a lot less, and get off the merry go around.

I got off the merry-go-round.
I'm fifty one and have had a better than average stereo since I was eighteen.
Speakers and amps, while they are not all created equal a person can learn to enjoy what they've got.
I've been lucky enough to have never lived in an area where the quality of the electrical signal effected the sound in any major negative manner. So I have no appreciation for high dollar power cords and have also come to realize that high dollar cabling to my ears is basically a waste of money.
Too many of us have forgotten why we bought a stereo in the first place. To enjoy the music. Which is where I'm back to after a quest that included many detours, pitfalls and poor decisions.
To answer this thread's orginator question: Put together a simple system that let's you go back to just enjoying the music.

Don't spend any money.
