Spectron musician III SE MkII mono block vs active

To coming back to this thread, I did quite some upgradings in my system since then and today fully upgraded Spectron monobloks dreive Magneplaners MG20.1r. As may coming a time to go further ie to add more Spectrons in to system I wonder what are benefits agains one set only.

Terry, would you please help to add your findings.

Thanks,
Boris

Whatever combo I have tried to drive my speakers with my pair of upgraded MIII Mk2's, the monoblock configuration yields a far superior sound than stereo mode.

These are world class amps and the only product that immediately limits any desires to try something different in your system!

Guma15, So now you have heard the benefit of operating with mono amps feeding your 20.1s
I am sure you have seen quite an improvement generated by your 20.1s
The next step I can suggest to make things a whole lot more better is active biamping if you are up to it, cost more money and time, but you will endup with 20.1 music you have never heard before.

You will need a first class active crossover and 1 more Spectron.

Your passive Magnepan crossovers are no longer used.
Your stereo preamp out will feed your active crossover, which will now generate a low and high outputs for both channels.
The 2 low outputs from your crossover will feed your 2 monos, each feeding only the bass panels of your 20.1s
The 2 high outputs from your crossover will feed 1 stereo MIII MKII amp which will feed both speakers mid/treble section.

Set up your crossover freqency, slope and Q according to the specs of the 20.1s
Use the level control on the crossover to adjust sound pressure levels between the bass and mid/treble panels.
Your bass panels will now be enjoying limitless power without blowing up the mid/treble sections. Since you can control individual sections at the crossover.
The crossover will also allow you to use all of the sweet spot on your preamp (sweet spot meaning withing 40 to 80% volume setting)

This setup is uncommon to many people and many of us are totally against active biamping.
One of the reasons for non active biamped systems with 4 discrete channels of audio power is that most speaker manufacturers do not allow you to remove their passive crossovers easily like Magnepan and a few others more who does.
