Are active speakers the best upgrade

First, thanks to the people here, I found out about ATC.
Many things were impressive. I don't listen to $15,000 speakers much so everything impresses me (not Wilson's) compared to what I own (Nautilus):
- I could hear 4-5 layers of tonality change a triangle being struck in an orchestra piece. I hear 1-2 on B&W. This happened with lots of instruments.
- My girlfriend didn't complain about the volume level. That's because there was virtually no distortion. I was shocked when she said she was fine with the volume. This has never happened before. The bass was big but highly damped. So the bass reverb did not hurt her chest. Neither one of us complained about the high's being harsh. Even on "hot" recordings. It was clear but not bright. I have become suspicious of Paradigm (for example) who may be using bright tweeters to give the perception of detail but on "hot" recordings, the trick becomes all too obvious.

So my gut reaction to this was the typical stereo enthusiast or audiophile is going crazy after wires, CDP, and DAC's which improve sound a few percent. All the while active designs go begging. But I would estimate they can give, like 10-30% improvements.

Also I believe the preamp can color the sound so one could use a tube pre or a tube DAC even if the amps are S.S. Or records too.

I don't need speakers which play 118 dB continuous. But on some level in this crazy hobby, I could see the $15,500 ATC 100's actually being worth it. The crystal clarity, lack of distortion, and effortless dynamics were awesome. ATC did have problems with soundstaging, naturalness in piano, playing at low volumes, and the open, expansive sound B&W does on vocals and the high freq's.

Bottom line: I want this in my system.

And I don't think it is possible in passive systems. If it is, please tell me how. Would a Triangle Celius on SET or JM Labs Micro Utopia do this? I can't think of anything else that might.

I read the Nautilus review online at Stereophile.com and it was informative on the lengths that B&W goes to. Their $40,000 Nautilus is active. Stereophile's article describes why they went passive and the problems it created on the 801's. People might want to check this review out.

I've been around the high end audio scene since about 1982, in one way or another, and have hands on dealt with so so so many speaker desings and technologies. I would personally like to see the new trend in loudspeaker manufacturing go towards "active" designs. The benefits and potential improvements in speaker performance fundamentally, from what we can all obviously pick up on, are ready to be realized! We've been through just about all the possible improvements we're every likely going to realize from the basic "passive" loudspeaker designs, that have been done over and over and over again, throughout the years, with variations here and there of course. Active speaker pottentially offer much better dynamic realism and transparency, less distortion, better spead, detail, etc. A number of speaker manufacturers have displayed what is possible, and the dramatic improvements that good active designs offer. From here, UP IS ACTIVE,...in my oppinion.
A couple of years ago, I was at Dunlavy Audio for a factory tour. I spent considerable time with John Dunlavy, and one of the questions I asked him was why more loudspeaker manufacturers don't make "active" designs? His reply was, he personally didn't think it was necessary, and that it was rather cost prohibitive and difficult to do well. Putting amps inside speakers, he said, was difficult to deal with, and most people didn't want to have to buy an external amp/crossover/speaker set-up, but rather wanted to pick their own gear anyway!..I've heard similar from many speaker designers. Bottom line, "passive" speakers are easier and cheeper to design.
We've since embraced the "powered/active" built in subwoofer thing in a lot of speaker designs as of the last few years. I think it's just a matter of time before we see more manufactures doing completely active speakers.
At the very least,I would like to see more higher end speaker using active woofers. This still increases dynamics and such on it's own.
The surgence of home theater, benefits of active subwoofers, crossing over to speakers at higher frequencies is of vital importance for passive monitor design in that arena at the very least. But for purrist high end sound reproduction or music, this scenario has it's limitations. No "passive" full range loudspeakers that I'm awar of can do justic to full range Dolby digital or DTS soundtracks, that is CERTAIN! The dynamics are just too great, and do best reproduced by "active" powered woofers down lower. I've heard first hand, that active monitors with active powered subs is even better!!!!
Now what we need is for more and more people to jump on that bandwaggon, and start creating more offerings of "full range" active's that will be adequate for music listening.
Lynn, Meridian, ATC, and active's with some obvious benefits over passive's. Horn speakers offer some decided advantages with increased dynamic effeciency...but horns have some serious dissadvantages, as we all know.
We've largely embraced traditional Piston driver design speakers, and the only way up from here is going to be going active. All the electrnic upgrades isn't going to improve things any more. We need more dirrect interaction fro amps and drivers if we want to see some improvement.
It's amazing that passive speakers sound as descent as they do, considering all the dissadvantages that passive crossovers induce. Going active is the next logical step really. Hey, the pro audio industry has realized this long ago...it's time for mainstream home audio to realize the same.

If we're going to

With regard to Lthkeeper's point, Paradigm had nice active speakers now discontinued. They are very good at marketing and my understanding is that they just could not sell them. People will not accept that package. Anyone else heard anything on why their active line was discontinued.

Unfortunately, do not hold your breath if you expect audio to be marketed in anything but separate little boxes as it is now.

I remain

TacT might lead us into the future.

I suspect that the fetish factor of amps, cables, crossovers made with air core inductors blah blah...etc. is just too great. An active system makes everything just too plain and simple for the obsessive compulsive audiophile.
