matching cartridge and speakers

There aren't any other two components in the audio chain which are more independent from each other than the cartridge and the speaker.
They both are interfaces to the purely electrical part of the audio chain.
Their jobs are entirely in reverse to each other and to choose a cartridge because of a certain speaker or vice verse means nothing than masking apparent faults in either.
There are huge interactions between the output stage of an amplifier and the x-over of a speaker.
This is an electrical interaction (resistance, inductance). Very important to match here.
The cartridge/tonearm is a spring-mass system - a mechanic-dynamic interaction between the two components.
Again - very important to match.
But I see no objective reason to match a cartridge to a given speaker - other than to mask sonic faults and so to fit into a personal sonic matrix.

Well, if I didn't knew before, than I know now why high-end audio is called by some bright minds "big boys toy- and dreamland".
Kind of "have no idea where to go from here, but will do so with high pace, past experience and all my strength" -approach.
This is a kind of naive devotion to audio, which helps a whole industry making their money with very little pressure regarding quality products.
In all respect - unless I am missing a brilliant self-sarcasm here - the last two posts by Geoch can't be serious.

Dear Geoch, this is not about elitist behavior nor such a state of mind - it is about logic and using one's brain.
"Matching" speaker and cartridge.
Oh please .... I certainly have a lot of understanding for many "each his own"-attitudes.
I am certainly not questioning Inna's original post - I have no problem with the initial question.
"Bravery" ultimately is the overcome of fear.
So fear has to be present to display bravery.
Don't think that Inna was driven by fear nor bravery here - he put out a unusual question.
Matching is of paramount importance in analog as well as digital audio.
You will find few people out there at all who are more concerned and involved in exactly this aspect of fine-tuning an audio set-up.

But - and this is my vital point here - even the idea of "matching" the first and last step of the audio chain implicit that you do so to mask/compensate accepted faults in the rest of the chain.
If this seems as a suitable way to anything near a balanced sounding system, than - sorry - you are lost from the very beginning.
And - it's élite, not elit.

Well - reality bites ...... which is an inevitable side-effect of reality .... it is real.
Enjoy the trip.
As a serious epigraph: do take care to match cartridge's dynamic-mechanical parameters with the moving effective mass and energy conductivity of your tonearm.
Likewise try to match the output stage of your amplifier according to your speakers x-over/voice coils inductance/resistance and capacitance.
Those are the things to match if you want to "match" speakers and cartridge.
Match their parameters with the direct partners.
For real world's sake and best results.

Dear Inna, I certainly have to the slightest problem with "stressing the art part" of the game. However I noticed the the 160+ top-flight audio set-ups I have visited and listened to in my life, that the "science" should be solved first.
You won't find any great painter in history who was without decent technique.
Finding the right cartridge for a given tonearm and phonostage is a task. And finding the "right" one can tailor the whole sound of your system to your needs. The initial idea of matching cartridge to speaker however means the entire rest of the audio chain - from cartridge leads clips to speaker wire - would behave like a perfect no-loss straight wire.
This is wishful thinking with no correlation to the real world.
Especially so, as speaker x-over and the cartridge itself do have very important parameters to be matched with their direct next partners (tonearm and output stage of power amplifier).
