I would be interested in an explanation why the topology for HF and UHF must be the same. I do not agree with this premise especially in 4 or 5 way systems where primarily the last octave only is demanded.

Rowuk, nobody wrote HF and UHF. If you read again, you will see Romy and I wrote HF and MF, which is very different subject. Anyway, in context of what you wrote – you are right – the UHF driver is not necessarily to have the same topology as the HF driver. Actually it doesn’t matter how it “sounds” if crossed above 20kHz. The only real world requirement is the absence of ultrasonic resonances, which can modulate the hearable range of the audio spectrum.  No UHF driver can improve the sound of a bad sounding HF driver, regardless the amount of the wishful thinking one has in that direction. Similarly, no tweeter can improve the sound of a bad sounding MF/widerange driver, especially in terms of transient deficiency or openness of the sound window. Actually any properly sounding HF driver does not need super tweeter support.

I personally use a second magnetostat behind the speaker angled to reflect off of the back wall and ceiling to add this dimension to my playback.

This is a multifaceted subject that deserves a separate thread, because it is important. If you recognize deficiency of back/upper dimensions of the “recreated” sound field, then the problem needs very different solution than just using speakers creating reflections in your room for more “spaciousness”.  What you are trying to do is to make your brain believe there is more realistic recreation of the recording’s original acoustic environment, but in fact what you do is to lower the contrast (sound difference) between the different recordings. Think why it is so.

Just because some audiophile claims "superior tone" or "absolute rules" does not make their personal preferences fact.

Rowuk, it has nothing to do with the personal preferences (taste of the listener). There is no room for personal preferences in serious audio. Also I have witnessed with my own ears a lot of installations claimed to have “superior tone” that are no more than a bag full of shits (sorry for the term). I personally do not trust anybody claiming to have superior tone without hearing how his system sounds in reality.

It is very interesting to note that the engineers that create our favorite recordings generally do not use systems that many audiophiles would even consider "adequate". I think this is a fact that you should consider before claiming anything "absolute". Somehow those people are getting superior sonic results with no subjectivity...................

I really don’t understand the connection of what I wrote in this thread with the sonic results somebody somewhere gets in a given studio. In most studios they have notoriously crappy and dead sound with very low contrast between the different recordings. Not to mention the fact it is highly unlikely to find a studio where they have successfully recreated the atmosphere of the recording.

It is NEVER the gun that makes the kill, it is he who pulls the trigger.

Yes, you are very correct by saying that, but still the man who pulls the trigger needs to have high quality drivers. His task is to use them in the most creative possible way, but if he doesn’t have good drivers, the game is over and he can’t kill any bird/dog/deer/you name it. One can cry, one can pray, but it is the naked truth. The question is what he can do about it!

In many cases ignorance is bliss and I often envy the listener that can get so caught up in the music that the warts do not matter.

I can successfully get caught up in the music even with my build-into the laptop speakers or any crappy and disgusting sounding so called “audiophile” speakers. But I don’t see what this “ignorance is bliss” has to do with this thread.
