Atma-Sphere amps with Eggleston Andra II's


I own a pair of Atma-Sphere MA2 Mk2.3 OTL monoblocks that are probably the one part of my system that will staying put for a long, long time. Currently, speakers are Dynaudio Confidence C2's. Preamp is an Atma-Sphere MP1 MkIII.

I'm looking to change/upgrade my speakers. As good as the C2's are, i.e., extremely coherent, very natural and detailed, nonfatiguing, they certainly don't have much "slam" factor. Now, I mostly listen to classical, jazz, and female vocals at moderate levels, but once in awhile still throw on some Cream, ZZ Top, Seger, ELP or whatever that demands some volume and presence in the low frequencies. I have been reading that the Andra II's can provide most, if not all, of the C2's traits but also add the missing lower octave and slam.

My question to Andra II owners is this: will 220 watts of OTL power drive the Andra II's properly? The MA2's can handle 4 ohm loads without difficulty as long as there are no crazy phase shifts. I am mainly concerned about running my amps dry.

TIA.

i have andra-2's and m.levinson 33h amps which is a great match. plus i've upgraded my wires to transparent ref-mm. after recently hearing halcro-driven wilson alexandrias i STILL couldn't be happier with my system. the andras only need 100W, and your amps have twice that. plus the andra-2 is easier to drive than the andra-1's. i am going to upgrade my speakers soon due to my cavernous room, so if you're interested let me know.
i don't know enough about atma-sphere amps or otl tube gear,
but all speakers have impedence dips, some go to 2 ohms for sure. but an amp with 220W should be able to comfortably drive
a wide range of speakers. i've used rowland m-12's (200W), a krell fpb-300, and a levinson 23.5 (200W) as well as the 33H
on the andras- even when they were series-I's- and NEVER was worried about having enough power.
