Well, my path was Stereo Plus>Stereo Extreme>Mono Extreme.

Had I to do it over again, it would have been Stereo Plus>Khartago Mono>Mono Extreme, latter a "maybe" given the efficiency of my Silverline Sonata IIs.

I have the ability to do a direct Stereo<>Mono Extreme comparison and hope to accomplish that during the next week.  We've been very pleased with the Mono Extreme configuration so far (3 months).

Hello,
 I'm new here and after reading many posts here and over at Audio Asylum i went straight to the standard Mono blocks and glad i did. The Extreme mono blocks i have a feeling i will be upgrading to by the end of this year.

I bought the mono's.  Then I told my wife I blew out the left channel and had to send them both back to make sure they matched after the left channel was repaired. I actually had them upgraded to Mono Extremes at that time.  

So mono's to mono extreme.

I told my wife I blew out the left channel and had to send them back

That is what I told my wife too.    
In my case, I went from Stratos stereo to Dual Mono and then finally to Mono Extreme.
