My system is presently compose of the following components:

Amplifiers: Devialet 200
Symphonic Line RG7 MK4

Speakers: Gemme Audio Tanto Karbon V3 with crossovers for each
speaker mounted in a separate or external enclosure which is
then linked to the speakers via Speakon Neutrix connectors.

Cables: 10 foot long Speakon Neutrix cables supplied by Gemme Audio.
7 foot long pair of Wireworld Silver Eclipse III Speaker Cables.
.75 meter pair of Kimber Selet 1036 RCA Cables
1 meter pair of Stage III silver cables.

Sources: Oppo 103D
Well Tempered Amadeus
Shelter 7000
Dynamique Design Magellen SDIF cable.

My main goal is to eliminate the crossover entirely by using the D200’s active crossover function.  I have no idea or inkling on how to proceed doing this.  I now place my audio future in your hands.  Useful links: http://www.canuckaudiomart.com/details/6...karbon_v3/ and this one; http://www.my-hiend.com/leoyeh/2011a/FicheV3-eng.pdf.  Thank you in advance for your responses.

I don't think you can do anything with a single D, except a cross over between an active sub and a pair of speakers.

Since your speakers are two ways speakers you would need two D200, and configure the one powering the woofers as a low pass and the one powering the tweeters as a high pass.

Not quite! I have one D250 and use filtered analog out with class D mono blocs (Kharma MP150 and now diy based on Anaview AMS0100) for the woofer. As my x-over frequency is around 250Hz the sound quality of these amps for the woofers is just fine! I doubt that a second pair of D250 would be significant better (I tried it mono with my D250 ).

Outstanding!  Thank you Jean and Music or Sound.  To make this work, I am planning to do the following:

1.  Fabricate adapter cables that will enable me to connect separate amplifiers for the highs and lows.  Both transducers have Speakon Neutrik speaker connectors.
2.  Reconfigure D200’s RCAs 1 and 2 as line out with high pass filters enabled.  This will be connected to the Symphonic Line and will drive the woofers.
3.  Enable low pass filter on D200’s speaker leads.  The Devialet will drive the tweeters.
4.  I still need to figure out the correct settings for the crossover.  Will need to consult Mr. Robert Gaboury,, Gemme Audio’s former owner and designer.  What filter order should I use?  1, 2 or 3?

After doing away with the crossover, I’m expecting the following improvements:  More direct and involving sonic signature.  Enhanced transparency and purity.  Transient attack, dynamic range and speed should significantly be improved.

Let me know if there is an easier way of doing this.  Feel free to make any corrections or make suggestions.  I thank all of you for your sound advice and guidance.  This chat forum is the best and you guys are awesome!
