No issue driving them, whatsoever

They are driven at least as well as
any similarly priced
solid state amp can. Tube amps will just sound different - that's just subjective. From a purely objective view - it's hard to beat 150 watts, oodles of current, excellent, long term reliability with 20 year warranty, smaller-than-typical hi-end margins that Klaus makes on his gear, and elimination of dealer network. That's all pretty much a knockout 'punch' and guarantee that you won't find much better solid state amps to drive them.
They drove my modded MMG's until, I too, both Odyssey Khartago Extreme SE version

I am getting back in to the audio hobby, and was interested in knowing if the Odyssey Khartago could drive magnepan mg12. I have just been reading equipment reviews, and like the magenpan sound after listening to the 1.6 QR at a friends. I cannot currently afford them or the simaudio amp he had driving them. That is where the Khartago comes in. I heard about the good trade-up policy and customer service at Odyssey. Are there any other recommendations?
